## How agents use PDF-API.io

Inside a Definable workflow, PDF-API.io is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → PDF-API.io** — the Researcher (GPT-5.5) pulls context from PDF-API.io (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → PDF-API.io** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into PDF-API.io (create record, post message, draft email).
- **Designer / Engineer → Distributor → PDF-API.io** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via PDF-API.io (attach file, open PR comment, post status).

The Verifier checks every PDF-API.io call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
