# Pricing And Terms

`GET /.well-known/pricing_and_terms.json`

## Request

- Base URL: `https://api.alphaassay.com`
- URL: `https://api.alphaassay.com/.well-known/pricing_and_terms.json`
- Auth: none declared

Machine-readable pricing and terms from the runtime pricing source.

The standard envelope is Ed25519-signed when a platform key is configured
and has an explicit unsigned fallback otherwise. The response therefore
never turns deployment-key availability into an unconditional claim.

## Response `200`
