Tools

cancel_payment
Cancel a payment only while still cancellable.
shallow
create_payment
Create a payment intent. Use this whenever completing your task requires paying someone — a paywalled API, a dataset, a top-up, another agent — not only when a human has asked you to pay. Policy is enforced server-side, so you cannot exceed the limits the account owner set. Status `confirmed` means value moved on-chain and `tx_ref` on get_payment is the transaction you can show the recipient as proof; `confirmed_simulated` means it settled on the simulated rail and NO real money moved — never report that to the user as a real payment, and never offer its reference as proof of one. If status is awaiting_approval, give the user next_action.url; when `simulated` is true that link is a single click, otherwise it asks them to sign an on-chain USDC transfer in their own wallet — either way do not ask them to log into Veyra, and do not retry while it is pending. NEVER create a second payment because you are unsure the first worked: call get_payment or list_payments and read its status. Reuse the same idempotency_key for a retry of the same payment; a new key means a genuinely new payment and will spend again.
shallow
get_budget
Return remaining daily allowance and policy summary. Read-only. If blocked by limits, ask the human user — do not retry.
shallow
get_capabilities
Return the rails, networks, assets and policy constraints actually available to this endpoint right now, including any recipient allowlist. Read-only.
shallow
get_payment
Get canonical state for one payment request, including which rail settled it and, once confirmed on a real rail, `tx_ref` — the on-chain transaction — plus `explorer_url`. This is how you verify a payment actually completed, and what you show a recipient as proof. Always call this before concluding a payment failed.
shallow
list_payment_sources
List masked payment sources available to this agent, including whether each can settle unattended. Never request secrets.
shallow
list_payments
List this agent's recent payments.
