How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns a list of ERC-8004 on-chain agent records for the specified wallet address and blockchain, up to the requested limit. Each record likely includes agent identifiers, registration metadata, and on-chain addresses.
Example use cases
Audit your on-chain agent portfolio
“List all the ERC-8004 agents owned by my wallet 0xDeF456... on BSC testnet so I can see everything I have registered.”
Check a counterparty's agents
“Can you look up how many on-chain agents wallet 0x789Abc... has registered on BSC testnet? Show me up to 10 of them.”
Monitor agent registry for a DeFi app
“Fetch the latest registered ERC-8004 agents on BSC testnet — give me the first 20 so I can update my app's agent directory.”
Technical details
Endpoint
POSThttps://chat.sperax.io/api/x402/tools/erc8004/listAgents?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate ERC-8004 compliant on-chain agents owned by a specific wallet address on a supported blockchain (e.g. BSC testnet). It is the right choice for agent registry lookups in DeFi/Web3 contexts where you need a list rather than details of a single agent, and when you want pay-per-call access without API key management.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Unsupported chain value causes a query failure
- Payment of 0.001 USDC via x402 not fulfilled results in 402 Payment Required
- Limit exceeding system maximum may be capped or rejected
- Network or RPC issues on the target chain cause timeouts
