🟢search_agents(query, remote_only, limit)
Search all indexed agent registries at once. Args: query: capability keywords, e.g. "pdf extraction", "solana rpc", "payments" remote_only: only return services callable over the network right now limit: max results (1-50)

}🟢quote_call(listing_id, payer_address, args_json)
Step 1 of a paid call (non-custodial). Fetches the service's payment requirements and returns the exact EIP-712 typed data your agent must sign with ITS OWN key. Nothing is charged until you sign and pass the result to call_service. If the service is free, says so. Args: listing_id: id from search_agents payer_address: your agent's wallet address (the key that will sign) args_json: JSON object of query args for the service

}🟢call_service(listing_id, tool, args_json, caller_ref, payment_json)
Call a listed remote service THROUGH Clearhouse and get a signed receipt. Routes the call via the matching protocol adapter (MCP / A2A / HTTP-x402), enforces spend caps, settles x402 paywalls (dry-run by default), and returns the result plus a cryptographically signed receipt binding intent -> execution -> settlement -> outcome. Args: listing_id: id from search_agents results tool: downstream tool name (omit to list the service's tools) args_json: JSON object of tool arguments caller_ref: opaque caller identifier for the receipt payment_json: for paid services — JSON {"authorization": typed_data.message, "signature": "0x..."} produced by signing quote_call's typed_data with your own key. Clearhouse relays it; it never sees your private key.

}⚪service_evidence(listing_id)
Observed facts about a listing: live probe results (handshake, latency, HTTP status) and routed-call history (count, success rate, distinct callers). Includes an arithmetic summary_index with published methodology and a confidence tier. This is EVIDENCE for the caller's own decision — not a safety rating, and Clearhouse never selects or executes on your behalf.
