API Reference

Tachyon provides a unified API for quoting, submitting, and tracking gas-sponsored transactions across supported blockchain networks.

Base URL

https://tachyon.rath.fi

Authentication

Transaction submission and quote endpoints require your Tachyon API key in the api-key header:

curl --request GET \
  --url 'https://tachyon.rath.fi/api/supported-chains'

Public status, account lookup, and supported-chain endpoints do not require the API-key header unless access controls are added at the deployment layer.
