CC0 public domain. Pass languages= as comma-separated codes (default "en") to control which language strings are included; pass maxClaimsPerProperty to cap how many statements come back per property (default 10).

Open Library book metadata search. Lookup by free-text query (matches title + author), or by individual title / author / ISBN (10 or 13 digit). Each record includes Open Library work key, title, author names + Open Library author keys, first publish year, edition count, cover image URL, sample ISBNs, publishers, languages, subject tags, fulltext flag, ebook access tier (public/borrowable/printdisabled/no_ebook), and canonical openlibrary.org URL. CC0 public-domain metadata.

Look up a public GitHub repository by "owner/name" slug. Returns full name, owner, description, homepage, default branch, primary language, topics, license (SPDX key + name), counts (stars / forks / watchers / open issues / subscribers / network), size, timestamps (created/updated/pushed), visibility, has-issues/projects/wiki/discussions flags. Unauthenticated GitHub access is rate-limited to 60 req/hour per server IP — returns 429 UPSTREAM_RATE_LIMIT when the bucket is empty.

Resolve a research organization via the Research Organization Registry (ROR). Pass id (a ROR id like 056y0v115 or its full URL) to fetch one org, or name to search by free text. Returns the canonical ROR id and name, organization type, status, founding year, location (city, country, GeoNames coordinates), website, Wikipedia link, external identifiers (GRID, ISNI, Wikidata, Crossref Funder), parent/child relationships, and aliases/acronyms. Data: ROR, free and CC0. The canonical institution key in scholarly metadata — pair with /api/papers/search and /api/paper/doi-lookup (author affiliations) and /api/research/author (ORCID). Use to disambiguate an institution name to a stable id before joining datasets.

Fetch a page from a tollbooth-registered domain. Costs the publisher's fee_credits from your credit balance (top up at /credits/buy) plus this route's price; 80% of the fee accrues to the publisher. Returns extracted page content. 404 if the domain isn't registered; 409 (not 402) if your credit balance is short.

Look up any US public K-12 school (~102k, NCES Common Core of Data). Search by name (partial), district (LEA name, partial), state (2-letter), city, zip, or exact ncessch (12-digit NCES id). Each school: NCES id, name, district + LEA id, address, phone, lat/lon, school level (1=primary 2=middle 3=high 4=other) and type (1=regular 2=special-ed 3=vocational 4=alternative), charter/magnet/virtual flags, enrollment, teacher FTE, grade span, CCD year. Results ordered by enrollment. Higher-ed sibling: /api/edu/college-scorecard. Public-domain federal data.

Search crates.io for Rust packages (keyless). Each result: name, latest stable version, description, total + recent downloads, and repository/homepage/documentation links. For agents discovering or vetting Rust dependencies.

Solar irradiance + PV-yield forecast for any coordinate (free/keyless, global). Returns a daily 1-16 day forecast: GHI (kWh/m²), peak sun hours, sunshine hours, and estimated yield per kWp of panels (at a 0.75 performance ratio). For rooftop-solar planning, agrivoltaics, and EV-charge scheduling. Complements energy.solar-resource (NREL long-run averages, US).

Search the npm registry for JavaScript/TypeScript packages (keyless). Each result: name, latest version, description, keywords, publisher, last-publish date, and npm/homepage/repository links. For agents discovering or vetting dependencies.

Unified scientific literature search across arXiv (preprints), PubMed (biomedical), and Semantic Scholar (cross-field, with citation counts). Returns a flat array of papers with stable schema: source, sourceId, doi, title, authors, abstract, year, publishedAt, citationCount, url, pdfUrl. Partial failures surface in the errors array rather than failing the whole call. Optional filters: since (YYYY-MM-DD), sources (subset), limit (max 20 per source).

Enumerate every model a manufacturer sold in a given model year via NHTSA's vPIC taxonomy database. Returns canonical NHTSA Model IDs + names plus the Make ID + name for reference. Useful as a discovery step before VIN decode (when the agent only knows make + year) or as input validation for vehicle.recalls / vehicle.complaints. Backed by NHTSA.gov; data is public-domain US government records.

Live news search. Returns recent headlines with title, URL, snippet, publisher source, relative age, and a breaking-news flag — real-time coverage past any model training cutoff. Supports count (1-20), offset, country (2-letter), and freshness (pd=past day, pw=past week, pm=past month, py=past year). Use for current events, market-moving developments, monitoring, and "what happened with X" questions. For general web results see /api/search/web; for Hacker News specifically see /api/news/hn-top.

Live web search. Returns ranked results with title, URL, snippet description, site name, and page age — fresh information past any model training cutoff. Supports count (1-20), offset for paging, country (2-letter, e.g. US), freshness (pd=past day, pw=past week, pm=past month, py=past year, or a YYYY-MM-DDtoYYYY-MM-DD range), and safesearch (off/moderate/strict).
