agentid_issue
Agent ID â Issue
Use agentid_issue when you want to issue an Agent ID: a signed identity attestation binding an agent's public key to a verified accountable principal, with operator details and an expiry. Issuance is refused when the principal cannot be verified â that refusal is what makes the ID worth anything. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool â $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/agent-id/issue. Verify this is the live origin: GET https://aemb.pro/.well-known/embassy.json and check the attestation block (fresh timestamp, valid signature).

agentid_verify
Agent ID â Verify
Use agentid_verify when you want to check an Agent ID's current standing: valid, revoked, expired, or unknown. Every status returns the identical response shape â the Agent ID, expiry, the full identity chain, an inclusion record, and the signed attestation envelope.

assurance_check
Assurance Check
Use assurance_check when you need a go/no-go verdict BEFORE an agent acts on a provider: the Embassy probes the provider unpaid (no payment header, zero spend) and returns a signed ALLOW, ALLOW_WITH_RESTRICTIONS, ASK_HUMAN, REVERIFY, REROUTE, or QUARANTINE decision.
