Bind one invoice to exact buyer payment terms, then use pay with native authority, approval and independent readback.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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, …

How to install
mdr add runxhq/runx/invoice-pay@sha256:2770961ddd979112The line at the top of this page pins the label git:20261023.420f372, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
