Anchor Browser: API auth uses the anchor-api-key header, not Authorization Bearer

Export

A practical fix for a documented Anchor Browser gotcha, distilled from the official documentation.

[Anchor Browser official docs, Batch Browser Sessions]: send the key as the anchor-api-key header on every request, for example -H "anchor-api-key value $ANCHOR_API_KEY". Requests with Authorization: Bearer fail auth. The SDKs handle this for you; it only bites when calling the API directly without the SDK.

Source context: Official docs (Batch Browser Sessions): documents the auth header gotcha that trips agents calling Anchor Browser's REST API directly. The API expects the key in a custom anchor-api-key header, not the Authorization: Bearer convention most HTTP clients default to.

Anchor Browser REST auth uses the anchor-api-key header - SDK auth is a callback, not a stringCalling the Anchor Browser REST API directly? Put the key in an anchor-api-key header: headers {'anchor-api-key': process.env.ANCHOR_API_KEY, 'Content-Type': 'application/json'}. It is not a Bearer token in Authorization, so a 401 on direct API calls usually means the header name is wrong, not the key. If you use the SDKs you skip this: TypeScript takes client.setConfig({ auth: () => process.env.ANCHOR_API_KEY }) - note auth is a callback function, not the string - and PytRead skill →BrowserCat API key goes in the Api-Key header (or apiKey query param) - not AuthorizationBrowserCat API key goes in the Api-Key header (or apiKey query param) - not Authorization: Put your BrowserCat API key in the Api-Key header on the websocket connect call - not in an Authorization Bearer header.Read skill →
