Every agent-payable API.

Package intelligence across npm, PyPI and crates.io in one call: latest version, license, repository, dependencies and download counts

Reports on a dependency at the point of installation. Give a package and, optionally, a version with its ecosystem (npm, PyPI, crates.io); the answer says whether that exact version exists, whether it is yanked or deprecated, and every advisory OSV lists against it. A version that was never published returns not_found with the real versions nearest to it. Verdicts: verified, advisory, yanked, not_found, unknown.

Check dependencies before your coding agent installs them: up to 20 packages per call (npm, PyPI, crates.io, Go, Maven, NuGet, RubyGems), one decision each: ALLOW, CAUTION or BLOCK with reasons. Catches hallucinated package names that do not exist (slopsquatting), known malware (OSV malicious-package feed, including versions already removed from the registry), typosquats one typo away from a popular package, critical and high vulnerabilities in the exact version with a safe upgrade, deprecated…

Calculates volume, girth and chargeable weight from package dimensions. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.

Retrieves current package metadata from npm, PyPI, crates.io or Maven Central. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.

Call before adding or upgrading a dependency: package-registry metadata for one package (PyPI or npm): latest version, summary, license, dependency count; PyPI also returns 30-day downloads.

Call before adding or upgrading a dependency: package-registry metadata for one package (PyPI or npm): latest version, summary, license, dependency count; PyPI also returns 30-day downloads.

Check npm package metadata and security before installation.

Returns the full version history of a package from a single normalised schema that covers seven ecosystems. Versions are ordered by semantic version, not alphabetically and not in registry order, so 1.10.0 sorts after 1.9.0 — the mistake that quietly breaks naive comparisons. For each version you get the publication timestamp, whether it is the registry default, whether it is deprecated and the deprecation reason as the registry states it.

Package Vulnerability Check (OSV). Package vulnerability check before you install or ship a dependency: known vulnerabilities for a specific version from OSV.dev (GitHub advisories, PyPA, RustSec, Go, npm...) with CVE aliases, severity, fixed-in versions and the recommended upgrade. npm, PyPI, crates, Go, Maven, NuGet, RubyGems, Packagist, Pub, Hex.

Quick technical SEO audit of one public page: status code, title, meta description, headings, links, images, load time and on-page checks (DataForSEO On-Page Instant Pages, no JavaScript rendering).

Call when an agent needs a structured SEO/tech audit of a public URL: HTTPS, status, title, meta, robots, canonical, JSON-LD, H1 count, load hints, score 0–100, issues[]. SSRF-safe. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/page-audit first.

Page-change monitoring for 30 days: we poll a URL on schedule, you poll us for changes

Machine-readable description audit fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.

Machine-readable description repair plan fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.

Fetches a URL and returns clean article text/markdown plus metadata. Deterministic, static HTML only, no JS rendering.

Given a set of specific page URLs, find the Google keywords those pages jointly rank for, with each page's position, URL and estimated traffic (ETV) per keyword, plus search volume, CPC, competition, difficulty and intent. Page-level, not domain-level. Optional exclude_pages narrows to keywords the pages rank for that others do not.

Every link on a web page with its anchor text, split into internal and external, with nofollow flags and the most-linked external domains. Use for SEO audits, crawling, backlink research or broken-link checks.

Fetch a reviewed public page and return its links with resolved absolute URLs and anchor text, the canonical URL, the declared meta robots directive, and how many links leave the host. Relative hrefs are resolved against the page, so a caller never has to guess a base.

Extracts OG tags, canonical URL, title, and meta description from any web page. Useful for link previews, SEO audits, and content enrichment.

Fetch a reviewed public page and return its title, every meta and Open Graph tag, and the canonical URL. No JavaScript is executed and no script content is read. Returns the licence and creator for the content alongside it, so reuse terms travel with the result.

Page metadata: Open Graph, Twitter card, canonical, feeds, JSON-LD types, language — Genesis402 / UnyKorn Operator Network

Page metadata as JSON - title, description, canonical URL, Open Graph, Twitter card, headings and JSON-LD

Read an allowed public HTTPS page and return a concise English or Japanese report with source quotes, URL and retrieval time. No login-only pages or JavaScript rendering.

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 reviewed public page and return its HTML tables as arrays of rows and cells. Bounded to ten tables, fifty rows each and twenty cells per row, and every bound that is reached is named in the warnings so a truncated table is never mistaken for a short one.

Machine-readable title audit fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.

Website change monitoring for agents that check in a loop: send a URL and get only what changed since your last call (added and removed lines of the page text), plus optional keyword alerts. First call saves a baseline and returns a cursor; pass the cursor on the next call. The cursor only advances when a change is reported, so nothing slips through between polls. Good for price pages, docs and changelogs, job boards, status pages, competitor sites, government notices.

Tell whether a public web page changed since you last looked, with nothing stored on this side. One fetch (15 s, 2 MB) takes the text a reader sees (hidden elements, scripts and styles dropped; a CSS selector narrows it to one region), collapses whitespace, strips any ignore entries (a literal substring, or /pattern/ for a regex, for timestamps and counters), and answers a sha256 fingerprint of that text with the origin's ETag and Last-Modified.

Load one public URL once in headless Chromium and report what that load measured: navigation timings (TTFB, DOMContentLoaded, load), Web Vitals read from the page's own performance entries (LCP, FCP, CLS, total blocking time from long tasks), total transfer bytes, request count, the 5 heaviest resources, render-blocking scripts and styles, and console errors. Mobile or desktop viewport.

Paid ($0.02 USDC via x402). Raw scraped content items from the last 4 hours across all Pulse sources. Proxied from the Pulse service. Compute-first / settle-after — you are never charged when Pulse is unavailable or returns an error.

Paid ($0.02 USDC via x402). Markets resolving within ?withinHours (1-72): odds, contested-vs-converged, liquidity, and order-book microstructure for the nearest expiries.
