information-retrieval

Reverse-DNS lookup for an IP: PTR record plus a best-effort list of other domains hosted on the same IP.

Extract all links from a page split into internal and external, each with anchor text and rel attribute, plus per-group counts.

Render an http(s) URL to a PDF (A4/A3/Letter/Legal/Tabloid) with print emulation; returns a JSON envelope with the PDF base64-encoded under pdf_base64, plus final_url, title, format, and size.

Extract page metadata: title, description, keywords, author, published/modified dates, canonical, language, favicon, and OpenGraph/Twitter card tags.

DNSSEC health check: reports whether a domain is DNSSEC-signed (DNSKEY), has a DS record at the parent, and whether the resolver authenticated the answer, with advisory warnings.

RDAP domain registration lookup: structured registrar, creation/updated/expiry dates, status, nameservers and a computed domain age. A parsed, snake_case JSON alternative to raw WHOIS text.

Fetch a PDF by URL and extract its text as JSON. Input: url (public http/https pointing to a PDF). Returns {url, pages, word_count, text}. Bounded to the first 50 pages; 3 MB max.

OpenAI-compatible text embeddings API — standard /v1/embeddings request shape: input as a string or a batch of up to 128 strings (64000 chars total on text-embedding-3-small, the default; 24000 on text-embedding-3-large). Flat $0.005 per call in USDC via x402, no OpenAI account or API key. Returns float vectors for RAG, semantic search, clustering, and dedup.

DNS lookup / nslookup / dig API — resolve the common DNS record types (A, AAAA, MX, TXT, NS, CNAME, SOA, PTR) for a domain. Parses SPF/DMARC from TXT plus DKIM at the default._domainkey selector, and cross-checks A records across Google/Cloudflare/Quad9 resolvers for propagation consistency.

US electricity grid — demand, generation mix (renewable/gas/nuclear), and stress signals across 7 regions

SSL/TLS certificate check: expiry, issuer, SANs, chain validity, hostname match, negotiated protocol/cipher, and weak-algo warnings for a public HTTPS host. Clean JSON.

Fetch the authoritative text of any section of the US Code of Federal Regulations by title and section number — for example title 12, section 1026.43 returns Regulation Z’s ability-to-repay standards. Returns the canonical citation, section heading, full plain text, Federal Register source credit, the as-of date, and a link to the official eCFR page. An optional date parameter (YYYY-MM-DD) retrieves the historical text in force on that date, back to 2017. Data from the Electronic Code of Federal Regulations (US GPO / Office of the Federal Register), public domain, updated daily — verify regulatory citations against the authoritative source instead of relying on model memory.

Fetch a URL and grade its HTTP security headers. Pass url (scheme optional — defaults to https). Returns an overall letter grade + score, the list of present/missing headers, and a per-header analysis with the live value and specific issues for: Strict-Transport-Security (HSTS max-age/includeSubDomains), Content-Security-Policy (flags 'unsafe-inline'/'unsafe-eval'/missing default-src), X-Frame-Options or CSP frame-ancestors (clickjacking), X-Content-Type-Options (nosniff), Referrer-Policy, Permissions-Policy, and Cross-Origin-Opener/Resource-Policy. Also flags Server/X-Powered-By info disclosure. Analyzed from the target's LIVE response headers through an SSRF-guarded fetch (private/loopback targets refused) — an LLM cannot see a site's current headers. For web-app security review, vendor assessment, and CI gates.

Search the global corpus of published fact-checks (ClaimReview) by free-text claim. Returns matching claims with the claimant, claim date, and each fact-check review's verdict (textualRating, e.g. "False", "Misleading", "True"), the publisher (PolitiFact, Snopes, FactCheck.org, Reuters Fact Check, AFP, …), the review URL, and review date. Covers every topic — politics, health, science, viral and misinformation claims. Optional language, recency (maxAgeDays), and publisher-site filters. Aggregated by Google from publishers' schema.org ClaimReview data. Use it to check whether a claim has been independently fact-checked and how it was rated, rather than asserting from training data.

Look up a CVE by id (e.g. CVE-2021-44228) across three authoritative vulnerability feeds in one call. Query: cve (CVE-YYYY-NNNN). Returns the canonical record — description, CVSS base score + severity + vector, CWE weakness ids, published/modified dates, reference links — plus whether it is on the US CISA Known Exploited Vulnerabilities catalog (with remediation due date and known-ransomware flag) and its EPSS exploit-probability score and percentile. The exploited and EPSS sections report independently, so one feed being unavailable does not fail the call. 404 if the CVE id is unknown. For triage, prioritization, and anti-hallucination on vulnerability claims.

Search code across GitHub with the code-search syntax (e.g. 'defineEndpoint repo:AlleyFord/2s' or 'addEventListener language:js'). Returns total match count + file name, path, repository, and URL for each hit. Read-only; no caller key needed.

List a repository's releases: tag, name, draft/prerelease flags, author, published time, and release notes body. Paginate. Track a project's version history. Read-only; no caller key needed.

Resolve a song/recording from MusicBrainz (the open, CC0 music encyclopedia). Pass artist + title, or a free-text query (Lucene supported). Returns ranked recordings with MusicBrainz ID (MBID), title, primary artist, length (ms), first-release date, and disambiguation. Keyless, public-domain core data. Use to canonicalize a track to its MBID or cross-reference identity.

List pull requests for a repository: number, title, state, author, draft flag, merged status + time, head/base branch, and created time. Filter by state (open/closed/all); paginate. Read-only; no caller key needed.

Search GitHub repositories with the full query syntax (e.g. 'x402 language:typescript stars:>100'). Sort by stars/forks/updated. Returns total match count + repos with stars, language, topics, license, timestamps. Read-only; no caller key needed.

Search the US Federal Register — proposed rules, final rules, notices, and presidential documents. Filter by free-text term, document type (RULE/PRORULE/NOTICE/PRESDOCU), agency slug (e.g., epa, fda, sec), and publication date range. Returns document_number, type, title, abstract, FR citation, agencies, publication_date, effective_on, comments_close_on, htmlUrl, pdfUrl, rawTextUrl. Public-domain US government data. Real-time — published daily, past LLM training cutoff.

A single Polymarket market by conditionId, slug, or id. Returns the question, outcomes + live prices (implied probabilities), CLOB token ids, USD volume + liquidity, dates, description, and URL. Pass one of conditionId / slug / id.

Programming-language breakdown of a repository: each language with its byte count and percentage of the codebase, sorted by size. Read-only; no caller key needed.

Commit history for a repository: sha, message, author name + GitHub login, date, and URL. Optionally filter by branch/tag (sha), file path, or author. Paginate. Read-only; no caller key needed.
