# Issue Fusor token

> Issues a short-lived LightAuth JWT bound to the Photon Fusor service (`codes.photon.spectrum.fusor`) and the requesting project. Use Authorization: Basic base64(projectId:projectSecret). Returns `{ token, expiresIn }` where `expiresIn` is the TTL in seconds. The token's `sub` is the project id; downstream Fusor services should treat it as the project-scoped capability.
