The current reply states the next action. The user approves card-backed purchases in the Envoy app. When Envoy offers a gift-card payment link, the user pays it themselves.

Contract files
| Download | Contents |
|---|---|
| OpenAPI | POST /tools/{tool} for every tool: authentication, inputs, the reply envelope and errors. |
| MCP catalog | The default MCP tools with schemas, annotations and descriptions. Connections Envoy identifies as ChatGPT omit report_checkout_result and report_checkout_step. |
| Synthetic examples | Inputs and replies validated against the contract. |
Envoy also serves its live schemas at GET /tools and GET /openapi.json on https://api.envoy.money. The examples use invented merchants, ids and card values. They make no network calls. Envoy has no test mode, so you cannot try a payment without real money.
Markdown
llms.txt lists every page with its Markdown URL. llms-full.txt holds the whole site. Both also live under /docs/. Each page has a View as Markdown link. Reading the docs does not refresh the tools or skills of a host.
