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 the on-chain reputation data for the specified ERC-8004 agent token, including a reputation score and a list of recent feedback entries (up to the requested limit) sourced from the specified blockchain network.
Example use cases
Vetting an agent before hiring
“Before I delegate funds to agent token 77, can you pull its reputation and last 10 feedback entries on bsc-testnet so I can see if it's been trustworthy?”
Monitoring own agent's reputation
“Check the on-chain reputation for my agent with token ID 15 on bsc-testnet and show me the 10 most recent pieces of feedback it has received.”
Comparing agent credibility in a marketplace
“I'm evaluating two agents — token ID 8 and token ID 23 — on bsc-testnet. Can you fetch the reputation and last 5 feedback entries for agent ID 8 so I can compare them?”
Technical details
Endpoint
POSThttps://chat.sperax.io/api/x402/tools/erc8004/getReputation?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to assess the trustworthiness or track record of a specific ERC-8004 agent token on-chain, especially in the SperaxOS / BSC ecosystem. Prefer this over generic off-chain reputation systems when you need verifiable, blockchain-sourced feedback tied directly to an agent's NFT identity.
Side effects
- Invalid or non-existent agentId returns an error or empty reputation data
- Unsupported chain value results in a lookup failure
- Network or RPC issues on the target blockchain cause a timeout
- Payment failure via x402 protocol results in 402 Payment Required response
- Limit value out of acceptable range may cause a validation error
