Open Payments API

New Open Payments API endpoints are updated with each data publication. The most recent endpoints are available at: /api/1/metastore/schemas/dataset/items?show-reference-ids.

All communication with the API is done through HTTPs, and errors are communicated through HTTP response codes. Available response types include JSON, XML, and CSV, which are selectable by the "extension" (.json, etc.) on the API endpoint or through content-negotiation with HTTP Accepts headers.
