What this source is
The eRulemaking program's API exposes rulemaking dockets, documents, and public comments across roughly 180 agencies as structured JSON, searchable by agency and date — the comment-and-docket layer of rulemaking that neither the Federal Register nor govinfo carries.

How we ingest it
- Channel
- API
- Method
- Would query the v4 documents endpoint by posted date (api.data.gov key we already hold, X-Api-Key header).
- Request budget
- the agency class: at most 1,500 requests per day shared across every agency web source, counted from the fetch log (failed requests count too)
- Politeness
- robots.txt is honored as observed — including each host's crawl-delay, exactly — and every request identifies itself as fapd/0.1 (Free Agentic Publication Digester; +https://fapd.info/bot.html; contact: hustleyourcity@gmail.com); a refusal is recorded, never evaded
- Capture and hash
- captured raw content is hashed (SHA-256) into the day's committed provenance manifest, hash-chained day to day (PROVENANCE.md)
