Bearer or header
Authorization: Bearer, or x-prism-key when a preflight would be in the way.
Read API v1.0.0
Take Prism somewhere else.
Three endpoints, one credential, and a version number in the path so a field that changes later cannot break an integration written today.
Daily quota
Counted per key, reset at midnight UTC, and returned in X-Prism-Quota-Remaining.
Provenance in the envelope
Every response names its source, when it was read, and whether it was live.
Errors say what to do
A 429 carries Retry-After. A 401 carries a link to this page.

A key belongs to an account rather than a browser, so it can be revoked from another device. Sign in to mint one.

Responses carry a disclaimer field for the same reason an exported memo carries one on its last page. Prism returns research data. Nothing it returns is a recommendation to buy, sell, or hold anything.
