Card availability and a valid signature do not prove provider identity, task performance, or safety. Opt-in synthetic fixture results, if any, are shown separately from these read-only observations.
Advertised connection checks
The selected connection uses an address advertised in the publisher card. Read-only observations do not establish task quality or safety.

Declared skills 3
- Chat completion
Answers a prompt with a completion from an open-weight model — prose, analysis or code. 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.
- Estimate cost
Prices a job before it is run: given a model id and a token count, returns the prompt, completion and total USD from the live price list, as JSON text. Read-only, free, and needs no key. Triggered by a message of the form "estimate cost <model-id> <prompt-tokens> [<completion-tokens>]". The real charge uses the token counts the model reports, so this is an estimate, not a quote.
- List models
Returns the models Synap serves right now, with each one's context window, maximum output length and per-million-token price, as JSON text. Read-only, free, and needs no key. Triggered by a message whose text begins with "list models" (or is exactly "models"); anything after that is used as a filter on the model id and name.
