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 compliant AI agents registered on the SperaxOS platform, including their metadata, capabilities, on-chain properties, and any relevant DeFi specializations. Each result represents a discoverable agent that can be further queried or invoked.
Example use cases
Discover yield optimization agents
“Find me ERC-8004 AI agents on SperaxOS that are specialized in yield farming or liquidity optimization on Base — I want to see what agents are available and what they can do.”
Build multi-agent DeFi pipeline
“I'm building an automated DeFi workflow and need to find registered SperaxOS agents that handle on-chain swaps or rebalancing — search the ERC-8004 agent registry and list their properties.”
Audit available DeFi agent ecosystem
“Give me a snapshot of all ERC-8004 compliant agents registered on SperaxOS so I can evaluate what autonomous DeFi capabilities are available on the platform right now.”

Endpoint
GEThttps://chat.sperax.io/api/x402/v1/erc8004/agents/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or enumerate AI agents registered under the ERC-8004 standard on the SperaxOS platform, particularly for DeFi-focused agent workflows on Base. Prefer this over generic agent directories when you specifically need on-chain DeFi agents payable via x402 USDC micropayments with no API key friction.
