  "description": "OpenAI-compatible inference on open-weight models, served on hardware Linkrra owns and operates. Send it a prompt and it answers with a model completion; ask it to list models or to estimate the cost of a job and it answers from the live price list. Zero data retention: prompts and completions are not stored, and a finished task cannot be read back.",

Billed per prompt and completion token to the Synap key on the request; with no key it returns a task in TASK_STATE_AUTH_REQUIRED and spends nothing. Name a model by putting its id in metadata.model, or leave it out and Synap routes to the cheapest model that can do the job. Stateless: send the whole conversation in the message, because nothing is remembered between calls.",
