How this service works
Which live agents can do X — and which of them are safe? Searches the skills, domains and names ERC-8004 agents declare, across the registrations this service sweeps continuously, and returns only the ones answering. Each row carries the endpoint to call, the wallet a payment reaches, and that wallet's risk band and sanctions verdict, so choosing between candidates is one call rather than a screening per row. Free alternative: GET /v1/search. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial.
Output
A paginated list of live ERC-8004 agents matching the query. Each row includes agentId, identifier, name, description, service endpoint URL, declared skills, declared domains, x402 support flag, payout wallet address, and a checkedAt liveness timestamp. Also returns total match count and a nextCursor for pagination.
Example use cases
Finding a live translation agent
“I need to hire an agent that can translate documents — search the ERC-8004 registry on Base for live agents with a translation skill and tell me their endpoints and wallet addresses so I can pay them.”
Discovering compliance domain agents
“Which agents on Base have declared themselves as working in the compliance domain and are actually responding right now? I want their names, service URLs, and payout wallets.”
Building an agent-of-agents pipeline
“I'm building an orchestration layer — can you find all live ERC-8004 agents on Base that accept x402 payments and have a data-extraction skill? Page through results if there are more than one page.”
Technical details
Endpoint
GEThttps://trust-agent.io/v1/search/agentsWhen to prefer
Use this endpoint when you need to discover live, reachable ERC-8004 agents on the Base chain that have declared specific skills or domains, rather than crawling tens of thousands of on-chain registration files yourself. It is the right choice when you need both a filtered capability match and liveness confirmation in one call, especially when building agent-of-agents workflows or automated procurement pipelines that need to pay agents via x402.
Side effects
- Missing all three required search fields (skill, domain, q) — returns 400 Bad Request
- Unsupported chain value (only 'base' is served) — returns 400 or empty result
- No live agents match the query — returns empty agents array with matches: 0
- Invalid or expired cursor — pagination fails or restarts from beginning
- Service unavailable or rolling sweep in progress — may return stale or partial results
