Tools of PHANTOM ID — agent payments (USDC on Base)
	Description		Read-only	Idempotent	Open world
`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.

`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 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_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 private key never leaves this process, only the signature is sent. Idempotent: replaying the same bind returns the existing binding. attestation_address comes from GET /.well-known/phantom-identity.json of the PHANTOM deployment (field attestation_address) — pass it here together with the chain_id so the local signature domain matches the server's. Key rotation is NOT exposed here (it needs the old AND new keys); call POST /v1/identity/rotate directly instead.

`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 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_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.

`submit_payment`Broadcast an authorized payment intent through IDPHANTOM.
