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 agent records from the SperaxOS registry, including agent addresses, metadata, and capability descriptors for DeFi agents deployed on Base. Each record follows the ERC-8004 standard for on-chain agent identity.
Example use cases
Discover available DeFi automation agents
“What ERC-8004 agents are currently listed on SperaxOS? I want to see all the DeFi agents I could potentially interact with on the platform.”
Find agents for a multi-agent workflow
“I'm building a DeFi automation pipeline — can you pull the full list of registered ERC-8004 agents on SperaxOS so I can pick which ones to chain together?”
Audit agent registry for compliance
“Fetch all agents in the SperaxOS ERC-8004 registry so I can audit which agent addresses are active and what capabilities they expose.”
Technical details
Endpoint
GEThttps://chat.sperax.io/api/x402/v1/erc8004/agents?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to enumerate or discover AI agent identities registered under the ERC-8004 standard on the SperaxOS platform specifically. Prefer this over generic blockchain indexers when you need SperaxOS-curated agent metadata, or when you want pay-per-request access without API key registration using USDC on Base.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 with payment requirements
- Malformed query parameters — returns 400 with validation error
- Registry temporarily unavailable — returns 503
- No agents match the provided filter criteria — returns empty list with 200
- Network congestion on Base causing slow settlement — delayed response
