Arxiv BulkACompanion to `domain-skills/arxiv/scraping.md`. Use the **arxiv** skill for search-and-fetch workflows. Use **this skill** when you need: - Bulk-harvesting all papers in a subject area or date window (OAI-PMH) - Citation counts, influential-citation scores, and cross-database IDs (Semantic Scholar) - Per-paper version history and submitter info (`arXivRaw` metadata) No API key required for either endpoint. Both return JSON or XML over plain HTTP. ---data-aigoapiVotes: 0GitHub stars: 9

Craigslist serves a full server-rendered HTML fallback (the `<ol class="cl-static-search-results">` block) intended for no-JS browsers.

EbayAField-tested against ebay.com on 2026-04-18 using `uv run python` with `http_get`. Chrome is NOT required — `http_get` returns full HTML on first access.developmentpythongoVotes: 0GitHub stars: 9

FramerAFramer.com web editor (framer.com/projects/...) — DOM selectors, Monaco code-editor workflow, publish quirks, and the things Framer's React canvas will not let automation touch.developmentjavascriptgoVotes: 0GitHub stars: 9
FredA`https://fred.stlouisfed.org` / `https://api.stlouisfed.org` — the canonical source for US macroeconomic time series (800,000+ series). The REST API at `api.stlouisfed.org` requires a free registered key. The web endpoints at `fred.stlouisfed.org` (CSV, JSON, HTML) are all blocked to headless HTTP — they consistently timeout with no response. For zero-key access use the BLS API (unemployment, CPI, payrolls) or World Bank API (GDP, growth rates, annual data).developmentgoapiVotes: 0GitHub stars: 9

IMDb's app shell is React with a shared design system (`ipc-*` classes). The same `li.ipc-metadata-list-summary-item` row primitive is reused across Top 250, MovieMeter, Search, and most other list pages — learn one selector set, scrape many pages. The `tt`-prefixed title ID in the URL (`/title/tt0111161/`) is IMDb's stable prima...developmentgoshellVotes: 0GitHub stars: 9

LinkedinAStarter guide based on LinkedIn Help pages. Treat LinkedIn as a browser-first domain: public URLs exist, but visibility, gating, and admin surfaces vary by account and role.toolsgoVotes: 0GitHub stars: 9

Add `mailto=your@email.com` to every request to use the polite pool (10 req/s vs 100 req/s limit, more reliable).data-aigoapiVotes: 0GitHub stars: 9
OpenstreetmapATwo fully public, no-auth APIs. Everything is a direct HTTP call — never need a browser. - **Nominatim**: geocoding (place name → lat/lon and reverse). Rate limit: 1 req/s. - **Overpass API**: spatial query engine over the full OSM dataset. Rate limit: 2 concurrent slots per IP on the public instance. **Do not use `http_get` without overriding `User-Agent`** — its default `Mozilla/5.0` is blocked by both APIs with HTTP 403. Pass `headers={"User-Agent": "browser-harness/1.0"}` on every call. ---developmentpythongoVotes: 0GitHub stars: 9
Package RegistriesA`https://registry.npmjs.org` · `https://api.npmjs.org` · `https://pypi.org` · `https://pypistats.org` Both registries expose full JSON APIs with no auth required.

PolymarketAPolymarket (`polymarket.com`) is a Next.js SPA. Its DOM is **selector-hostile** — class names are CSS-module hashes that rotate on every deploy (`styles_row__aB3cD`), and there are **no `data-testid` attributes anywhere on the event pages** (confirmed April 2026: `document.querySelectorAll('[data-testid]').length === 0` on a live event page). **Always try the public Gamma API first.** It returns everything the page shows — outcomes, prices, volume, comments, tags — as clean JSON, and it doesn...developmentpythongoVotes: 0GitHub stars: 9

PubmedA`https://pubmed.ncbi.nlm.nih.gov` — 37 M+ biomedical citations. **Never use the browser for PubMed.** All data is reachable via `http_get` using the NCBI E-utilities REST API. No API key required; a free key raises the rate limit from 3 to 10 req/s.data-aigonodeVotes: 0GitHub stars: 9
QuoraA`https://www.quora.com` — Q&A platform. One reliable access path: `http_get` with a Chrome UA against question, answer, topic, and profile pages.
