Users fund an application with whatever they hold, on whatever rail, and the application receives exactly what it needs, credited exactly once. This document is the single source of truth for every wire type. Server handlers, the SDK, the checkout, and the dashboard all consume types generated from it. A handler change without a regenerated type fails CI. servers: - url: https://api.useroutr.com/v1 description: Production - url: https://api.sandbox.useroutr.com/v1 description: Sandbox security: - secretKey: [] tags: - name: Funding intents - name: Funding addresses - name: Customers - name: Registry - name: Webhooks paths: /funding_intents/{id}/accept: post: tags: - Funding intents summary: Accept a quote, pinning its route operationId: acceptQuote parameters: - name: id in: path required: true schema: type: string - $ref: '#/components/parameters/IdempotencyKey' requestBody: required: true content: application/json: schema: type: object required: - quote_id properties: quote_id: type: string responses: '200': description: The intent, now awaiting payment, with pay instructions. content: application/json: schema: $ref: '#/components/schemas/FundingIntent' default: $ref: '#/components/responses/Error' components: parameters: IdempotencyKey: name: Idempotency-Key in: header required: true description: Required on every mutating request.
