How this service works
OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana, Algorand and Polygon via x402.
Output
Returns a JSON object containing the agent's on-chain identity (owner address, agentURI) and a reputation aggregation (getSummary) computed over the supplied client addresses from the Base ERC-8004 registries.
Example use cases
Vetting an agent before delegation
“Before I hand off this task to agent ID 12345, can you check its on-chain ERC-8004 reputation and identity on Base, looking across client addresses 0xAAA111 and 0xBBB222, so I know if it's trustworthy?”
Aggregating agent trust across clients
“I need a reputation summary for agent 87048 aggregated over these three client addresses on Base: 0xC1, 0xC2, 0xC3 — pull the identity info and getSummary from the ERC-8004 registry.”
Auditing agent ownership and URI
“Who owns agent ID 55001 on-chain? Can you fetch its agentURI and reputation summary from the Losbeto ERC-8004 registry for client addresses 0xDEAD and 0xBEEF?”
Technical details
Endpoint
GEThttps://markets.losbeto.xyz/agent-reputation?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify or audit an AI agent's on-chain identity and aggregated reputation across multiple client relationships, specifically within the ERC-8004 standard on Base. Prefer this over off-chain reputation systems when trust provenance must be cryptographically verifiable, or when building agent-to-agent trust workflows that require on-chain attestation.
Side effects
- Missing required agentId parameter returns an error
- Invalid or non-existent agentId returns empty or null identity fields
- Malformed client addresses may cause registry lookup failure
- Payment not completed via x402 results in 402 response blocking data
- Base network unavailability causes lookup timeout or error
