How popular is that npm package? Get download counts and trends for any npm package straight from npm's public download API. Pull the total downloads over a period (last day, week, month, year or any custom YYYY-MM-DD:YYYY-MM-DD range), the full per-day download time series, the monthly totals over the last year to spot growth or decline, and compare several packages side by side ranked by downloads (up to 128 at once, scoped @org/name packages supported). Every call is live (no cache). 5 endpoints. Built for popularity dashboards, package-comparison pages, trend charts, dependency-health scoring and "which library won" analyses. Distinct from an npm registry-metadata lookup — this is the download time series. No upstream key, no cache.

How big is that npm package? Get the minified and gzipped bundle size of any npm package — plus its dependency count, the size contributed by each dependency, peer dependencies, whether it ships an ES module and whether it is side-effect-free — in a single call. Pin a version ([email protected]) or get the latest, and pull the bundle size across a package's recent versions to spot regressions over time. Powered by the public Bundlephobia service; results are live (no cache). 3 endpoints. Built for frontend performance budgets, bundle-size CI checks, "cost of adding this dependency" tooling, and dependency dashboards.

Ask a single feature×browser question, list or filter features by category, search features by keyword, and get the browser/agent list with version histories and the category/status legend. Backed by the public caniuse-db dataset (refreshed every 12 hours); query results are computed live. 7 endpoints. Built for build tooling, polyfill decisions, compatibility dashboards, linters and documentation. No upstream key.

Disposable / temporary email as an API — no key, no signup. Spin up a throwaway mailbox in one call (you get back the address plus a token), then receive real inbound email and read it: list the inbox, open any message with its full HTML and plain-text body and attachments, mark messages seen, delete a single message, or delete the whole mailbox when done. List the available mailbox domains and look up account details (quota, usage). Perfect for sign-up flows, OTP / verification-code capture, QA and end-to-end test automation, and throwaway registrations. Inbox endpoints use a per-mailbox token returned by /v1/account/new (pass it as ?token= or an Authorization: Bearer header).

Read Discord in real time — no bot token, no OAuth, no login. Resolve any invite (a discord.gg/<code> link or bare code) to its full server: name, description, icon/banner/splash image URLs, verification and NSFW levels, premium (boost) tier and count, vanity URL, the channel it points to, the user who created it, and live approximate member and online counts.

Fetch and evaluate any publisher's ads.txt / app-ads.txt — the IAB authorized-digital-sellers standard. Pass a domain and the check endpoint fetches its ads.txt server-side, then returns every seller record parsed into its fields — advertising system, the publisher's seller/account id, the DIRECT or RESELLER relationship and the optional certification-authority id (TAG-ID) — alongside counts (direct, reseller, distinct ad systems) and the declared variables OWNERDOMAIN, MANAGERDOMAIN, CONTACT and SUBDOMAINS. The verify endpoint answers the one question programmatic-advertising integrations actually ask: is this advertising system, with this publisher id, authorized to sell this domain's inventory? — returning an authorized boolean and the matching records. A missing file is reported as found:false (not an error), and soft-404 HTML pages are detected and rejected so you never parse a "page not found" as records. The request is made server-side and private or internal targets are refused (SSRF-guarded). Built for ad-tech supply-chain verification, SSP/DSP onboarding checks, anti-fraud and inventory audits. An ads.txt seller-authorization checker — distinct from the security-contact file reader (securitytxt), the robots.txt crawlability evaluator (robots) and the sitemap parser (sitemap).
