  "accessNotes": "Reads only the public, unauthenticated JSON REST API of the Grand Comics Database: https://www.comics.org/api/series/?format=json&page=N (50 series per page, 232,658 series → ~4,650 pages), /api/series/<id>/, /api/issue/<id>/ and /api/publisher/<id>/ (publisher names are cached per run). No login, no cookies; the API root advertises only `series` and `publisher` list endpoints and ignores filter parameters, so discovery is a resumable page walk (cursor = {page, index}). robots.txt (Cloudflare managed): `User-agent: *` Allow: / with Content-Signal search=yes, ai-train=no — we index catalog facts and link back; the HTML pages and the /download/ SQL dumps sit behind a Cloudflare managed challenge and a GCD account and are NOT fetched. GCD data is CC-BY-SA: every record carries the licence in metadata and links to its comics.org issue page. Rate limit (verified live 2026-09-08, twice): the API throttles per client at roughly 60 requests per hour (HTTP 429 with Retry-After up to ~1,741 s; a second burst of 7 requests 30 min later was refused again), so each hourly run is capped at maxRequestsPerRun (30) requests spaced 2.5 s apart, stops cleanly at its last checkpoint on the first 429 (anomaly 'rate_limited'; the comics.org domain policy sets maxRetries 0 so the engine never sleeps on Retry-After) and resumes from the cursor next run. Cover prices are stored as originalMsrp only when GCD prints an ISO currency (e.g. '0.12 USD'); dates with unknown day/month (GCD '00') are kept as year only, never completed.",
