Documentation
Nouron Pass documentation
The Nouron Pass API v1 and MCP server share one open contract, openapi.json, and this documentation is derived from it: what you read here is what the API defines today.
What is here
Five pages, all derived from the same contract. Start with the quickstart.
- Quickstart: Check your key, request a payment and read the result in three steps.
- Errors: Every error code, its HTTP status and what to do.
- Events: Every event type and how it is delivered by webhook.
- Versioning: Which changes are compatible and which ones break.
- Limits: Rate limits, sizes and quotas.
The contract
The source of everything is an OpenAPI 3.1 document. If anything on these pages and the contract disagree, the contract wins.
Access
This documentation describes the API v1 contract in the practice environment, which uses practice money. Access opens in batches from the waitlist.
