Invoice Pay
Use this for an invoice whose reference, payee, amount and currency are already
known. Choose a held buyer connector: wallet/evm for its supported x402 method,
or link for a Stripe MPP charge with an approved one-time spend request.
There is no universal EVM address requirement, USD conversion or implicit
provider selection. Each method must actually support the invoice currency.
Supply invoice_id, positive whole amount_minor, explicit currency,
payee.payment_url, the selected connector's public request, the original
parent_payment_authority and a stable idempotency_seed. Inspect the connector
to construct the exact request. For x402 the request is its payment_signal;
for Link it is the payment.mpp input with the original challenge and approved
spend request. Put wallet keys, SPTs, card data and bearer tokens in none of these
fields; credential custody belongs to the connector.
The deterministic invoice check binds the requested amount, currency and exact
payment URL to the supplied invoice. pay then checks its parent mandate and
owns payment execution. Native admission remains authoritative for capability,
run budget, human approval, effect custody and provider confirmation. A supplied
invoice or mandate never creates permission to spend. Invoice authenticity and
procurement approval must come from the caller's evidence or procurement lane.

Completion and recovery
The result is pay's original payment evidence. For x402, completion includes
confirmed payment and the paid resource's 2xx response. For Link, it confirms
the exact original paid amount and transaction; it does not publish a merchant
HTTP body or prove delivery. The outer receipt binds this evidence to the
caller-supplied invoice reference, not a claim that the processor authenticated
the invoice or fulfilled a separate contract.
Stop on mismatched invoice terms, unsupported method/currency, missing wallet authority, denied approval or uncertain readback. Reuse the original invoice, provider identifiers and request key. Resume the original effect or schedule its readback; never pay again under a new identity. This skill does not mark an accounting record paid, send a message or approve a purchase on the caller's behalf. Those remain separate governed actions.
