API Reference

Browse every endpoint, see request + response schemas, and try live calls against the CryptaChain API — all in one place. The reference is powered by Stoplight Elements and loaded dynamically from our OpenAPI spec, so it stays in sync with what the API actually exposes.

Try it with your API key

1. Grab a key from the developer portal (the free tier is enough to start).
2. Click any endpoint below and expand Try it.
3. Paste your key into the X-Api-Key header and hit Send.

Responses come back from the live API — there is no mock layer.

• Swagger UI: https://api.cryptachain.com/swagger-ui
• Postman: import the raw JSON URL above as a collection; set the X-Api-Key variable in your environment.
• SDK generators: feed the spec to openapi-generator or the Stoplight CLI to produce clients in any supported language.

Official SDKs we maintain: Java, Python, TypeScript.
