SDK API

Complete reference for the SDK class.

For detailed ID format documentation, see Models Reference.

Initialization

sdk = SDK(
    chainId=11155111,  # ChainId
    rpcUrl="https://sepolia.infura.io/v3/YOUR_PROJECT_ID",
    signer=None,  # Optional[Any] (omit for read-only)
    registryOverrides=None,  # Optional[Dict[ChainId, Dict[str, Address]]]
    indexingStore=None,
    embeddings=None,
    ipfs=None,  # Optional[str]: "node" | "filecoinPin" | "pinata"
    ipfsNodeUrl=None,
    filecoinPrivateKey=None,
    pinataJwt=None,
    subgraphOverrides=None,  # Optional[Dict[ChainId, str]]
)

import { SDK } from 'agent0-sdk';

const sdk = new SDK({
  chainId: 11155111,
  rpcUrl: 'https://sepolia.infura.io/v3/YOUR_PROJECT_ID',
  // Optional for read-only operations
  privateKey: process.env.PRIVATE_KEY,

  // Browser alternative (EIP-1193):
  // walletProvider,
  // registryOverrides?: Record<ChainId, Record<string, Address>>
  // subgraphUrl?: string
  // subgraphOverrides?: Record<ChainId, string>
});

Note: The chainId parameter sets the SDK’s default chain. When you provide an agentId without a chainId prefix, the SDK uses this default chain.

TypeScript note: signer is still accepted as a backwards-compatible alias for privateKey.

Advanced: direct contract calls (TypeScript)

The TypeScript SDK no longer exposes legacy registry helpers. If you need direct on-chain access:

• Use sdk.registries() to get the registry addresses.
• Use viem directly (recommended) with a minimal ABI for the function(s) you need.
• Alternatively, you can use the SDK’s exported ViemChainClient if you want a thin wrapper around common read/write operations.

Agent Methods

createAgent

Create a new agent.

agent = sdk.createAgent(
    name: str,
    description: str,
    image: Optional[str] = None
) -> Agent

import { SDK, Agent } from 'agent0-sdk';

const agent: Agent = sdk.createAgent(
  name: string,
  description: string,
  image?: string
);

loadAgent

Load an existing agent by ID.

agent = sdk.loadAgent(agentId: str) -> Agent

import { SDK, Agent } from 'agent0-sdk';
import type { AgentId } from 'agent0-sdk';

const agent: Agent = await sdk.loadAgent(agentId: AgentId);

Discovery Methods

searchAgents

Search for agents with filters.

results = sdk.searchAgents(
    filters: Union[SearchFilters, Dict, None] = None,
    options: Union[SearchOptions, Dict, None] = None,
    **kwargs
) -> List[AgentSummary]

import { SDK } from 'agent0-sdk';
import type { SearchFilters, SearchOptions, AgentSummary } from 'agent0-sdk';

const results: AgentSummary[] = await sdk.searchAgents(
  filters?: SearchFilters,
  options?: SearchOptions
);

Parameters (exhaustive)

searchAgents(filters, options) is the unified entrypoint that blends agent discovery + reputation filtering.

Multi-chain note: filters.chains enables multi-chain execution. Results are returned as a flat AgentSummary[] containing agents from all queried chains.

Default chains: if you omit filters.chains, searchAgents() queries chain 1 plus the SDK’s default chainId, de-duplicated (so chain 1 is never queried twice). This applies both with and without filters.keyword.

getAgent

Get a single agent summary.

agent = sdk.getAgent(agentId: str) -> AgentSummary

import { SDK } from 'agent0-sdk';
import type { AgentId, AgentSummary } from 'agent0-sdk';

const agent: AgentSummary | null = await sdk.getAgent(agentId: AgentId);

Parameters:

• agentId (str / AgentId): Agent ID in format "agentId" (uses SDK’s default chain) or "chainId:agentId" (explicit chain, e.g., "11155111:1234") Examples:

# Using default chain
agent = sdk.getAgent("1234")  # Uses SDK's default chain

# Explicitly specify chain
agent = sdk.getAgent("11155111:1234")  # ETH Sepolia

// Using default chain
const agent = await sdk.getAgent('1234');  // Uses SDK's default chain

// Explicitly specify chain
const agent = await sdk.getAgent('11155111:1234');  // ETH Sepolia

Feedback Methods

prepareFeedbackFile

Prepare an off-chain feedback file payload (optional).

feedback_file = sdk.prepareFeedbackFile({
    "text": "Optional rich feedback text",
    "capability": "tools",
    "name": "financial_analyzer",
    "skill": "financial_analysis",
    "task": "analyze_balance_sheet",
    "context": {"userId": "user123"},
    "proofOfPayment": {"txHash": "0x...", "amount": "0.01"},
})

import { SDK } from 'agent0-sdk';
import type { FeedbackFileInput } from 'agent0-sdk';

const feedbackFile: FeedbackFileInput = sdk.prepareFeedbackFile({
  text: undefined,
  capability: 'tools',
  name: 'financial_analyzer',
  skill: 'financial_analysis',
  task: 'analyze_balance_sheet',
  context: { userId: 'user123' },
  proofOfPayment: { txHash: '0x...', amount: '0.01' },
});

giveFeedback

Give feedback on-chain (optionally with an off-chain feedback file).

tx = sdk.giveFeedback(
    agentId="11155111:123",
    value=85,
    tag1="data_analyst",
    tag2="finance",
    endpoint="https://api.example.com/feedback",
    feedbackFile=feedback_file,  # optional
) -> TransactionHandle[Feedback]
feedback = tx.wait_confirmed(timeout=180).result

import { SDK } from 'agent0-sdk';
import type { AgentId, Feedback, FeedbackFileInput, TransactionHandle } from 'agent0-sdk';

const tx: TransactionHandle<Feedback> = await sdk.giveFeedback(
  agentId,
  85,
  'data_analyst',
  'finance',
  'https://api.example.com/feedback',
  feedbackFile // optional: FeedbackFileInput
);
const { result: feedback } = await tx.waitConfirmed();

getFeedback

Get single feedback.

feedback = sdk.getFeedback(
    agentId="11155111:123",
    clientAddress="0xabc...",
    feedbackIndex=0
) -> Feedback

import { SDK } from 'agent0-sdk';
import type { AgentId, Address, Feedback } from 'agent0-sdk';

const feedback: Feedback = await sdk.getFeedback(
  agentId: AgentId,
  clientAddress: Address,
  feedbackIndex: number
);

Note: feedbackIndex in the feedback ID is 0-based (first feedback = 0, second = 1, etc.)

Note: Both SDKs take separate parameters instead of a single feedbackId string.

searchFeedback

Search feedback with filters.

results = sdk.searchFeedback(
    agentId="11155111:123",  # optional
    agents=None,             # optional: search across multiple agents
    reviewers=None,
    tags=["data_analyst"],
    capabilities=["tools"],
    skills=["financial_analysis"],
    tasks=None,
    names=None,
    minValue=0,
    maxValue=100,
    include_revoked=False,
    first=100,
    skip=0,
) -> List[Feedback]

import { SDK } from 'agent0-sdk';
import type { AgentId, Address, Feedback } from 'agent0-sdk';

const results: Feedback[] = await sdk.searchFeedback(
  filters: {
    agentId?: AgentId;
    agents?: AgentId[];
    tags?: string[];
    reviewers?: Address[];
    capabilities?: string[];
    skills?: string[];
    tasks?: string[];
    names?: string[];
    includeRevoked?: boolean;
  },
  options?: { minValue?: number; maxValue?: number }
);

Parameters:

• agentId (str / AgentId, optional): Agent ID in format "agentId" (uses SDK’s default chain) or "chainId:agentId" (explicit chain)
• agents (List[AgentId] / AgentId[], optional): Search across multiple agents (use "chainId:agentId" for cross-chain)
• reviewers (List[Address] / Address[], optional): Reviewer wallet addresses (enables “all feedback given by a wallet” when used without agentId)

Notes:

• You must provide at least one filter (agentId/agents/reviewers/tags/etc.). Empty searches are rejected to avoid accidental global queries.
• Reviewer-only searches require a configured subgraph (no on-chain fallback).

searchAgents (feedback / reputation filters)

searchAgentsByReputation was removed. Use searchAgents() with filters.feedback instead.

results = sdk.searchAgents(
    filters={
        "chains": "all",
        "feedback": {
            "minValue": 80,
            "tag": "enterprise",
            "includeRevoked": False,
        },
    },
)

const results = await sdk.searchAgents(
  {
    chains: 'all',
    feedback: { minValue: 80, tag: 'enterprise', includeRevoked: false },
  }
);

revokeFeedback

Revoke feedback.

result = sdk.revokeFeedback(
    agentId: str,
    feedbackIndex: int
) -> Feedback

import { SDK } from 'agent0-sdk';
import type { AgentId, TransactionHandle, Feedback } from 'agent0-sdk';

const tx: TransactionHandle<Feedback> = await sdk.revokeFeedback(
  agentId: AgentId,
  feedbackIndex: number
);
await tx.waitConfirmed();

TypeScript Note: Returns a TransactionHandle<Feedback>.

appendResponse

Append response to feedback.

feedback = sdk.appendResponse(
    agentId: str,
    clientAddress: str,
    feedbackIndex: int,
    response: Dict
) -> Feedback

import { SDK } from 'agent0-sdk';
import type { AgentId, Address, URI, TransactionHandle, Feedback } from 'agent0-sdk';

const tx: TransactionHandle<Feedback> = await sdk.appendResponse(
  agentId: AgentId,
  clientAddress: Address,
  feedbackIndex: number,
  response: { uri: URI; hash: string }
);
await tx.waitConfirmed();

TypeScript Note: Returns a TransactionHandle<Feedback>. Response parameter is an object with uri and hash properties.

getReputationSummary

Get reputation summary for an agent.

summary = sdk.getReputationSummary(
    agentId: str
) -> Dict

import { SDK } from 'agent0-sdk';
import type { AgentId } from 'agent0-sdk';

const summary: { count: number; averageValue: number } = await sdk.getReputationSummary(
  agentId: AgentId,
  tag1?: string,
  tag2?: string
);

Parameters:

• agentId (str / AgentId): Agent ID in format "agentId" (uses SDK’s default chain) or "chainId:agentId" (explicit chain)

Transfer Methods

transferAgent

Transfer agent ownership to a new address.

tx = sdk.transferAgent(
    agentId: str,
    newOwnerAddress: str
) -> TransactionHandle[Dict[str, Any]]
result = tx.wait_confirmed(timeout=180).result

import { SDK } from 'agent0-sdk';
import type { AgentId, Address, TransactionHandle } from 'agent0-sdk';

const tx: TransactionHandle<{
  txHash: string;
  from: Address;
  to: Address;
  agentId: AgentId;
}> = await sdk.transferAgent(
  agentId: AgentId,
  newOwner: Address
);
const { result } = await tx.waitConfirmed();

Parameters:

• agentId (str / AgentId): The agent ID to transfer

• newOwnerAddress / newOwner (str / Address): Ethereum address of the new owner Returns:

• Python: Dict[str, Any] containing:

• txHash (str): Transaction hash

• from (str): Previous owner address

• to (str): New owner address

• agentId (str): Agent ID that was transferred

• TypeScript: Object with typed fields { txHash: string; from: Address; to: Address; agentId: AgentId } Raises/Throws:

• Python: ValueError: If agent not found or transfer not allowed

• TypeScript: Error: If agent not found or transfer not allowed Example:

# Transfer agent using SDK method
tx = sdk.transferAgent(
    agentId="11155111:123",
    newOwnerAddress="0x742d35Cc6634C0532925a3b8D4C9db96C4b4d8b6"
)
result = tx.wait_confirmed(timeout=180).result

print(f"Transfer successful: {result['txHash']}")
print(f"New owner: {result['to']}")

// Transfer agent using SDK method
const tx = await sdk.transferAgent(
  "11155111:123",
  "0x742d35Cc6634C0532925a3b8D4C9db96C4b4d8b6"
);
const { result } = await tx.waitConfirmed();

console.log(`Transfer successful: ${result.txHash}`);
console.log(`New owner: ${result.to}`);

Comparison with Agent.transfer():

• sdk.transferAgent() is a convenience method that loads the agent first

• agent.transfer() works directly on an existing agent instance

• Both methods perform the same validation and transfer logic

• Use sdk.transferAgent() when you only have the agent ID

• Use agent.transfer() when you already have an agent instance Important Notes:

• Only the current owner can transfer the agent

• Agent URI, metadata, and all other data remain unchanged

• Transfer is irreversible - ensure the new owner is correct

• Invalid addresses and self-transfers are automatically rejected

• Address validation includes checksum format verification

Owner Utility Methods

getAgentOwner

Get the current owner of an agent.

owner = sdk.getAgentOwner(agentId: str) -> str

import { SDK } from 'agent0-sdk';
import type { AgentId, Address } from 'agent0-sdk';

const owner: Address = await sdk.getAgentOwner(agentId: AgentId);

Parameters:

• agentId (str / AgentId): The agent ID to check Returns:

• Python: str - The current owner’s Ethereum address

• TypeScript: Address - The current owner’s Ethereum address Raises/Throws:

• Python: ValueError: If agent ID is invalid or agent doesn’t exist

• TypeScript: Error: If agent ID is invalid or agent doesn’t exist Example:

owner = sdk.getAgentOwner("11155111:123")
print(f"Current owner: {owner}")

const owner = await sdk.getAgentOwner("11155111:123");
console.log(`Current owner: ${owner}`);

isAgentOwner

Check if an address is the owner of an agent.

is_owner = sdk.isAgentOwner(
    agentId: str,
    address: Optional[str] = None
) -> bool

import { SDK } from 'agent0-sdk';
import type { AgentId, Address } from 'agent0-sdk';

const isOwner: boolean = await sdk.isAgentOwner(
  agentId: AgentId,
  address: Address
);

Parameters:

• agentId (str / AgentId): The agent ID to check

• address (str / Address, optional in Python, required in TypeScript): Address to check (Python defaults to SDK’s signer address) Returns:

• bool: True if the address is the owner, False otherwise Raises/Throws:

• Python: ValueError: If agent ID is invalid or agent doesn’t exist

• TypeScript: Error: If agent ID is invalid or agent doesn’t exist Example:

# Check if current signer is owner
is_owner = sdk.isAgentOwner("11155111:123")

# Check if specific address is owner
is_owner = sdk.isAgentOwner("11155111:123", "0x742d35Cc6634C0532925a3b8D4C9db96C4b4d8b6")

// Check if specific address is owner (address is required in TypeScript)
const isOwner = await sdk.isAgentOwner(
  "11155111:123",
  "0x742d35Cc6634C0532925a3b8D4C9db96C4b4d8b6"
);

canTransferAgent

Check if an address can transfer an agent (i.e., is the owner).

can_transfer = sdk.canTransferAgent(
    agentId: str,
    address: Optional[str] = None
) -> bool

// Note: This method is not available in TypeScript SDK
// Use isAgentOwner instead, which serves the same purpose
const canTransfer = await sdk.isAgentOwner(agentId, address);

TypeScript Note: This method is not available in the TypeScript SDK. Use isAgentOwner() instead, which serves the same purpose.

Parameters:

• agentId (str): The agent ID to check

• address (str, optional): Address to check (defaults to SDK’s signer address) Returns:

• bool: True if the address can transfer the agent, False otherwise Example:

# Check if current signer can transfer
can_transfer = sdk.canTransferAgent("11155111:123")

# Check if specific address can transfer
can_transfer = sdk.canTransferAgent("11155111:123", "0x742d35Cc6634C0532925a3b8D4C9db96C4b4d8b6")

// Use isAgentOwner as equivalent
const canTransfer = await sdk.isAgentOwner(
  "11155111:123",
  "0x742d35Cc6634C0532925a3b8D4C9db96C4b4d8b6"
);

Utility Methods

chain_id / chainId

Get current chain ID.

chain_id = sdk.chain_id() -> int

import { SDK } from 'agent0-sdk';
import type { ChainId } from 'agent0-sdk';

const chainId: ChainId = await sdk.chainId();

TypeScript Note: Method is async and uses camelCase naming.

registries

Get registry addresses.

registries = sdk.registries() -> Dict[str, str]

import { SDK } from 'agent0-sdk';
import type { Address } from 'agent0-sdk';

const registries: Record = sdk.registries();

set_chain

Switch to a different chain.

sdk.set_chain(chain_id: int) -> None

// Note: This method is not available in TypeScript SDK
// Create a new SDK instance with the desired chainId instead
const sdk = new SDK({
  chainId: newChainId,
  rpcUrl: newRpcUrl,
  // ... other config
});

TypeScript Note: This method is not available in the TypeScript SDK. Create a new SDK instance with the desired chainId instead.

isReadOnly

Check if SDK is in read-only mode.

is_readonly = sdk.isReadOnly -> bool

import { SDK } from 'agent0-sdk';

const isReadOnly: boolean = sdk.isReadOnly;

TypeScript Note: Property access (not a method), uses camelCase naming.
