# Authentication Every endpoint except `GET /health` requires a **Bearer JWT** (HS256, signed with the launcher's stored secret): ``` Authorization: Bearer ``` The permanent token is shown in *Settings → Automation API* (copy it from there). Pressing **Regenerate token** rotates the signing secret live — the new token works immediately and every previously issued token is invalidated at once. There is no separate API key and no token-minting endpoint: the token itself is the credential. Missing/invalid token → `401` with an empty body. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.proxyshard.com/proxyshard/shardx-launcher-api/authentication.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
