OpenAPI Specification

  title: Glyph Signup API
  description: 'A language for agents: encode content into the cheapest substrate the reading model can parse, with honest per-reader token math. Fillin is the retrieval product — a time-series index of the dev internet that closes the gap between an LLM''s training cutoff and now.'

      summary: Signup Api
      description: 'Mint a one-time trial bearer key worth TRIAL_QUERIES base queries.


        The API lane of /signup — smithery.yaml has promised agents a 20-query

        trial key, but the only implementation was the Stripe checkout HTML page,

        a dead end for an autonomous agent. This endpoint closes that gap: no

        wallet, no card, no human. One key per IP per UTC day (reuses the probes

        quota table under a ''trial:'' prefix), burst-capped by slowapi.


        The raw key is returned ONCE and only its hash persists — same contract

        as the Stripe lane.'
