Readr OGPreview

Batch web extraction: turns up to 5 public URLs into LLM-ready markdown in one paid call (comma-separated urls param; 0.02 USDC regardless of count — under half the per-URL price). Failed URLs come back with ok:false, no retry charge logic needed since settlement is one-shot.

Deep page intelligence report for any URL: SEO checks with scored issues, heading outline, image alt coverage, internal/external link analysis, JSON-LD structured data, technology fingerprints, word count and reading time. Query param: url (required).

Domain intel for any hostname: DNS A/AAAA/MX/NS/TXT records via DoH plus RDAP registration data (registrar, created, expires, statuses). Query param: domain (required).

Full-domain intelligence report in one call: complete DNS sweep (A/AAAA/MX/NS/TXT/SOA/CNAME), RDAP registration data (registrar, dates, statuses), DNSSEC presence, mail posture summary (SPF/DMARC/DKIM selectors), TLS certificate snapshot (issuer, expiry, protocol), Certificate Transparency subdomain census, and HTTP probe (status, redirects, https enforcement, server header) — each section scored, overall weighted score and verdict. Query param: domain (required).

Executable header forensics for a file URL (defensive reverse-engineering): parses ELF (32/64, LE/BE), PE (32/64) and Mach-O headers — architecture, PIE/ASLR, NX stack, section entropy, imports, compiler/linker timestamps, interpreter, overlay and security verdicts (packed/signed/mitigations). Static parsing only, the sample is never executed. Query param: url (required). Max 8 MiB.

Fetches any public web page and returns LLM-ready output: title, byline, publish date, canonical URL, word count and clean markdown body text. Query param: url (required).

RSS/Atom feed reader: fetches any feed URL and returns the channel title plus the latest items (title, link, published date, summary) as clean JSON. Query params: url (required), limit (optional, default 10, max 50).

Static file triage for any file URL (defensive reverse-engineering): magic/format identification, MD5/SHA-1/SHA-256 hashes, Shannon entropy with packed-region detection, embedded-file signature scan and classified string extraction (URLs, IPs, paths, crypto markers). The sample is fetched and analysed in memory only — never executed. Query param: url (required).

HTTP endpoint health checker: follows the redirect chain of any URL, reports per-hop status codes, total timing, final URL and response headers. Query params: url (required), maxHops (optional, default 10).

Email deliverability audit for a domain: MX records, parsed SPF with qualifier grading, DMARC policy grade, DKIM selector probing (12 common selectors), and DNSBL reputation checks (dronebl, SpamCop, Barracuda, Spamhaus) on resolved mail IPs. Query param: domain (required).

Link preview extractor: fetches any URL and returns its title, description, Open Graph and Twitter Card images, favicon, canonical URL and dominant meta tags — the data needed to render a rich preview card. Query params: url (required).

Multi-page site audit: crawls up to 6 pages of a domain (homepage plus the most-linked pages), checks titles, meta descriptions, h1s, image alts, canonicals, viewport, response times and sitemap/robots presence, then returns a 0-100 score with an actionable issues list. Query params: domain (required), pages (optional, default 5, max 10).

Subdomain enumeration via Certificate Transparency logs (crt.sh, with Cert Spotter fallback): unique subdomains with issue/expire date ranges, grouping by function (www, mail, api, dev, admin, cloud, cdn...), issuing CAs and cert counts. Recon-grade attack-surface mapping for a domain. Query params: domain (required), limit (optional, default 100, max 250).

TLS/SSL audit for any host: live handshake — certificate chain details (subject, issuer, SANs, expiry, fingerprint), negotiated protocol and cipher, a TLSv1.0/1.1/1.2/1.3 support matrix, and a graded findings list. Query param: domain (required; host or URL).

Worldwide weather lookup: current conditions plus 7-day daily forecast for any place name or lat/lon pair, powered by Open-Meteo. Query params: place (name lookup) OR lat+lon; unit (optional: metric|imperial, default metric).
