Tools
| Tool | Description | Behaviour |
|---|---|---|
| agentid_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 — 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 — $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). | Changes data |
| agentid_renew | Use agentid_renew to renew an Agent ID: a fresh Agent ID, same identity chain, new expiry; old one retired. revocation_signature over agent-id-revoke:<OLD_agent_id> (64-char lowercase ID) — same contract as retiring: EIP-191 personal_sign (envelope required; raw ECDSA fails), 0x 65-byte hex; or ed25519 nacl.sign.detached, 64-byte hex. Signer: principal or Embassy-for-cause. 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 — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/agent-id/renew. Verify this is the live origin: GET https://aemb.pro/.well-known/embassy.json and check the attestation block (fresh timestamp, valid signature). | Changes data |
| agentid_revoke | Use agentid_revoke to retire an Agent ID instantly. revocation_signature: hex signature over the message agent-id-revoke:<agent_id> (64-char lowercase ID). EIP-191: personal_sign the message string (envelope required; raw ECDSA fails), 0x 65-byte hex, matched to the principal's revocation key. ed25519: nacl.sign.detached, 64-byte hex. Signer: principal or Embassy-for-cause. 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 — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/agent-id/revoke. Verify this is the live origin: GET https://aemb.pro/.well-known/embassy.json and check the attestation block (fresh timestamp, valid signature). | Changes data |
| agentid_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 — the Agent ID, expiry, the full identity chain, an inclusion record, and the signed attestation envelope. Unknown IDs report unknown; never an error. 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 — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/agent-id/verify. Verify this is the live origin: GET https://aemb.pro/.well-known/embassy.json and check the attestation block (fresh timestamp, valid signature). | Changes data |
| 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. UNVERIFIED is the honest default for unknowns — never a smear, never a badge. 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 — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/assurance/check. Verify this is the live origin: GET https://aemb.pro/.well-known/embassy.json and check the attestation block (fresh timestamp, valid signature). | Changes data |
| cert | Lightning Cert — proof your document existed, settled in seconds. $0.25. Paid tool — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/cert. Verify this is the live origin: GET https://aemb.pro/.well-known/embassy.json and check the attestation block (fresh timestamp, valid signature). | Changes data |
| compute_alerts | Use compute_alerts when you want to know when GPU spot prices made a significant move: returns the current price-move alert list, sealed into your signed receipt. 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 — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/markets/compute/alerts. Verify this is the live origin: GET https://aemb.pro/.well-known/embassy.json and check the attestation block (fresh timestamp, valid signature). | Changes data |
| compute_history | Use compute_history when you need GPU compute market history: a bounded time series of per-GPU cheapest/median/offer counts — or whole-market history when no GPU is named — sealed into your signed receipt. Prices are ephemeral asks, never delivered-cost guarantees. 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 — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/markets/compute/history. Verify this is the live origin: GET https://aemb.pro/.well-known/embassy.json and check the attestation block (fresh timestamp, valid signature). | Changes data |
| compute_spot_prices | Use compute_spot_prices when you need the live GPU spot market snapshot: current per-GPU-hour prices with filters for GPU model, offer type, verified hosts, minimum host reliability, GPU count, and result size. GET the paid_url with an x402 v2 PAYMENT-SIGNATURE header carrying the USDC authorization. Paid tool — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/markets/compute/spot. Verify this is the live origin: GET https://aemb.pro/.well-known/embassy.json and check the attestation block (fresh timestamp, valid signature). | Changes data |
| correct_copy | Use correct_copy when you want a $25 correction pass over draft copy: normalizes formatting, verifies every link is alive, confirms your required terms appear, and scans for black-box leaks — then returns the corrected copy with a verification report and a signed receipt. You pay for the pass, never the method. 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 — $25.00, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/copy/correct.

| preflight_check | Use preflight_check before your agent spends on a paid tool or endpoint: the Embassy answers WHO is paid, WHAT is delivered, what CHANGED, the full COST, and WHO TAKES A CUT — then returns a signed PROCEED, PROCEED_WITH_CAUTION, BLOCKED, or UNKNOWN verdict with the full proof envelope. 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 — $0.25, USDC on Base or Arbitrum One.

| ticker_shelf | Shop an economic idea for $0.25: one delayed scan (CBOE options, Nasdaq equities) for a ticker, a head-to-head ("COMPARE two tickers"), or a theme ("BEST a theme").
