What it can do

Tool names and descriptions exactly as the server reported them on Nov 10, 2026. The maker wrote them, not us; we show them as plain text.

• phantom_register

  One-line onboarding: creates an IDPHANTOM account for the configured payer wallet, pays the $2 USDC registration with a locally-signed EIP-712 authorization and returns the api_key. Requires PHANTOM_PAYER_PRIVATE_KEY and PHANTOM_ROUTER_ADDRESS in the environment. The api_key is s

• phantom_authorize_budget

  Funder-signed EIP-712 AgentWalletAuthorization: lets an account spend up to max_units of USDC (6-decimal units, e.g. '1000000' = $1) with an optional daily cap, without giving away the wallet. Requires PHANTOM_FUNDER_PRIVATE_KEY in the environment; the signature is produced local

• phantom_bind_identity

  Registers an agent_id as a portable identity for this account via POST /v1/identity/bind. The proof-of-possession is an EIP-712 IdentityBinding signature produced LOCALLY with PHANTOM_IDENTITY_PRIVATE_KEY (environment variable only, never a command-line flag — AGP-057); the priva

• quote_payment

  Create an IDPHANTOM payment quote with transparent platform fee (0.5%, min $0.01 USDC). Returns a payment intent ready for the payer's EIP-712 signature. Free: quoting never moves funds.

• authorize_payment

  Attach the payer's EIP-712 PaymentAuthorization signature to a quoted payment intent. The signature is produced locally by the payer's wallet; it authorizes up to maximumTotalAuthorized, expiring at expiresAt. No funds move until submit_payment.

• submit_payment

  Broadcast an authorized payment intent through IDPHANTOM. The platform relays the on-chain transaction; exactly one broadcast per intent is enforced server-side (retries return the already-submitted transaction hash). This is the step that settles funds.

• verify_payment

  Verify an IDPHANTOM payment receipt: cryptographic checks (EIP-712 signature, payer recovery), expiry, and the on-chain state of the authorization (free/used/cancelled). Free for receipts of payments the caller participated in; paid via the receipt-verifier for third-party receip
