Web & Data

Page speed API - Google PageSpeed Insights (Lighthouse) performance audit for a URL on mobile or desktop. Returns the performance score plus lab Core Web Vitals (LCP, FCP, CLS, TBT, Speed Index, TTI) and, where available, real-user (CrUX) field data. Data source: Google PageSpeed Insights.

Fetch a URL and extract every hyperlink on the page, each resolved to an absolute URL and classified as internal vs external (by registrable host), with its anchor text, rel attributes (nofollow, sponsored, ugc) and whether it opens in a new tab. Returns internal/external/nofollow counts. For SEO link audits, internal-linking analysis and outbound-link/nofollow compliance checks.

Scholarly search API - academic papers and research articles for a query, powered by OpenAlex. Returns ranked works with title, authors, year, venue, DOI, citation count and open-access status. A google-scholar-style research / scholarly articles search for agents. Data source: OpenAlex (CC0).

Extract plain text and metadata (title, author, producer, page count) from a PDF supplied by URL or base64 — heavy pdf.js parsing an agent can't self-run.

Read a single XBRL financial concept for a company (by CIK or ticker) from its as-filed statements. Give the concept's XBRL tag (e.g. Revenues, NetIncomeLoss, Assets, EarningsPerShareDiluted) and optionally the taxonomy (default us-gaap, also dei). Returns the label and, per unit (USD, shares), recent datapoints with period end, value, fiscal year/period, form, filing date and accession. Bounded, as-reported output.

Discover a site's XML sitemaps (via robots.txt Sitemap: directives, an explicit sitemap URL, or the conventional /sitemap.xml) and parse them into a bounded list of URLs with their lastmod, changefreq and priority. Follows sitemap-index files to their child sitemaps. Fetches and URL counts are capped (with a `truncated` flag) to stay fast and memory-bounded. The reliable way for an agent to enumerate a site's pages.

Fetch a public page and grade its on-page SEO: title and meta-description length, H1 and heading outline, canonical, meta-robots indexability, viewport/lang/charset, hreflang, Open Graph and Twitter Card completeness, image alt coverage and word count — plus optional focus-keyword placement and density. Returns a pass/warn/fail verdict per check and an overall 0–100 score.

On-page SEO audit API - crawl a single URL and return its on-page SEO health: overall score, title & meta description, H1, word count, internal/external link and image counts, load timing (LCP, TTI) and a list of detected issues (missing meta, broken status, not-https, images missing alt, slow load, …).

Google Shopping product search API - search Google Shopping by keyword (US) and get ranked product offers across sellers. Live Google Shopping data: title, product URL, image, seller, price, currency, star rating, review count, Google product id and delivery info. Compare product prices across merchants. No matches returns empty results.

Fetch a site's robots.txt and evaluate crawl permissions: given a URL (plus optional extra paths) and a user-agent, return whether each path is allowed or disallowed, the rule that matched, the user-agent group, the crawl-delay and any declared sitemaps. Implements the Robots Exclusion Protocol (RFC 9309) with longest-match-wins, Allow-over-Disallow tie-breaking and * / $ wildcards.

Search the persisted Wirecutter recommendation database by product type, pick name, review title, category, and model tokens. Search is lexical today; pass concise, spelling-corrected product/category nouns instead of vague natural-language intent.

SYNTHORA fed-watch: US reference-rate funding pulse — SOFR/EFFR/TGCR/BGCR/OBFR with volumes, percentile dispersion and the SOFR-EFFR spread (the funding-stress signal before it hits the news). Cross-check of 5 independent official NY Fed series. The input for Fed/CPI prediction markets. Free official source, no key. $0.01 USDC x402 Base.

Research brief with citations: a quick, sourced answer to any question or topic. Use before writing, deciding, or searching deeper. Pass q (question). Returns a summary, 3-6 cited bullets and sources (official docs, Wikipedia, Stack Overflow, GitHub, papers) with URLs and dates; off-topic sources dropped. 0.01 USDC (Base/Polygon/Arbitrum/Solana/Avalanche/Sei). Errors are never charged: 400 bad input, 422 nothing found or target unreachable, 503 busy.

Search the periodic table by name or symbol substring. Exact matches rank first, then prefix matches, then substring matches. Returns up to `limit` elements (default 20) plus the total match count.

Find personally identifiable information in a text blob: emails, phone numbers, credit cards (Luhn-validated), IBANs (mod-97 validated), IPv4/IPv6 addresses, US SSNs and JWTs. Returns every match with its type and character offsets, plus per-type counts. Validated — not just pattern-matched — to keep false positives low. Fully offline.

Run HTTP + SSL + DNS + domain-expiry in one call and return a combined health snapshot. The single pre-flight check to run before crawling, deploying to, or depending on a site — cheaper and one round-trip instead of four.

Encode a word with the classic Soundex algorithm (letter + 3 digits) for phonetic matching of names.

Generate a random Luhn-valid TEST card number for the given network (default Visa). For testing only — these are not issued cards and cannot be charged. The response is always flagged `test:true`.

Generate cryptographically-secure random bytes, returned as hex, base64 or base64url.

Roll dice notation with a cryptographically secure RNG, optionally repeated. Returns per-die rolls, the kept dice and the total for each roll.

Look up a country by its ISO 3166-1 alpha-2 code, alpha-3 code, numeric code or English name. Provide exactly one field. Returns all codes plus the UN region.

Parse a semantic version into major/minor/patch, prerelease and build metadata.

Generate one or more UUIDs. Supports v4 (random), v1/v7 (time), and v3/v5 (namespaced).

Validate a UUID and report its version and variant.
