• authorize_paymentAuthorize a 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.

• phantom_authorize_budgetAuthorize a spending budget for an account

  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 locally. Policy templates: 'micro' ($1/tx, $5/day, 30d) and 'subscriptions' ($2/tx, $5/day, 30d) — pilot caps kept deliberately low; explicit max_units/daily_cap_units/expires_in_days override any template. The account's own api_key is sent as authentication (first binding requires it).

• phantom_registerRegister an IDPHANTOM account (self-serve)

  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 shown exactly ONCE in this response — store it as PHANTOM_API_KEY immediately. Without a payer key configured, pass payer_wallet to get manual instructions instead.

• quote_paymentQuote a 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.

• submit_paymentSubmit a paymentcan change or delete data

  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_paymentVerify a payment receiptread-only

  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 receipts.
