WordPress Directory API

healthy 3,638 Subscribers

The official WordPress.org plugin and theme directory as an API — the registry behind the ~40% of the web that runs on WordPress. Look up any plugin or theme by its slug for its name, version, author, user rating and rating count, active-install count and total downloads, the WordPress and PHP versions it requires, last-updated date, homepage, support URL and direct download link; and search the directory by keyword (plugins or themes), with results ranked by active installs. Covers the 60,000+ free plugins and 13,000+ themes on WordPress.org, from WooCommerce, Yoast SEO and Elementor to Contact Form 7 and Jetpack. Live from the official api.wordpress.org. Ideal for WordPress dashboards and site managers, plugin/theme catalogs, compatibility and update tooling, and the WordPress developer ecosystem. Open data from WordPress.org.

US Hospitals API

Search and filter more than 5,400 Medicare-certified hospitals across the United States and territories: filter by state, city, free-text name, hospital type (acute care, critical access, psychiatric, childrens, veterans and more), ownership category, whether the hospital offers emergency services, and the CMS overall star rating. Look up any hospital by its CMS facility id, and read metadata listing every state with its hospital count plus the available types and ownership categories for building filter UIs. Each record returns the facility id, name, full address, county, phone number, type, ownership, emergency-services flag and overall rating. Built on the official CMS Hospital General Information dataset. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for healthcare directories, patient-facing apps, insurance and care-navigation tools, and research.

GST API

Validate and decode Indian GSTINs (the 15-character Goods & Services Tax Identification Number) instantly and entirely offline. The validate endpoint checks the structure and recomputes the official GSTIN check digit — the base-36 weighted algorithm the GSTN itself uses — and confirms the embedded state code is real, returning a clear valid/invalid verdict with the specific reasons a number fails. The decode endpoint breaks a GSTIN into its parts: the GST state/UT code and its name, the embedded 10-character PAN, the PAN holder type (company, individual/proprietor, firm/LLP, HUF, trust, government and more, read from the PAN's 4th letter), the entity registration number, the default 'Z' slot and the check digit. A states endpoint returns the full GST state-code reference for building dropdowns and lookups. Everything is pure computation — no network call, no key, no cache — so it is fast and private, ideal for checkout and onboarding forms, invoicing and e-invoice/e-way-bill pipelines, vendor master data cleansing and bulk validation. A structural GSTIN validator and decoder — distinct from EU VAT-number validation (vat), IBAN bank-account validation (iban) and card-number checks (creditcard). Note: this verifies the number's structure and check digit, not whether it is actively registered in the GSTN portal. No upstream key, no cache.

ads.txt API

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). No upstream key, no cache.

api.oanor.com/adstxt-api

Sitemap API

Fetch and parse an XML sitemap (the sitemaps.org protocol). Pass a sitemap URL and the parse endpoint fetches it — following redirects and transparently gunzipping .gz sitemaps — and returns its type: a urlset with every URL and its lastmod, changefreq and priority, or a sitemapindex listing the child sitemaps, with offset/limit paging for large files. The urls endpoint goes further: when the sitemap is an index it fetches the child sitemaps too and flattens every page URL into a single list, with a configurable cap on URLs and child sitemaps and a truncated flag so you stay in control. The request is made server-side and private or internal targets are refused (SSRF-guarded). Built for SEO audits, building crawl queues and content inventories, change monitoring and migration checks. A sitemap fetcher and parser — distinct from generic XML-to-JSON conversion (xml), the robots.txt evaluator (robots) and the on-page SEO audit (seo). No upstream key, no cache.
