Each: agency, feed, title, date, link, a short summary and, for SEC and CFPB, the respondent named in the title. Filters: agency, words (q), days (1-90). The feeds hold the latest 25-30 items each.
• POST/translate—No price listedTranslation with Llama 3.1 8B: up to 6,000 characters per call, formatting, names, numbers and URLs kept, source language detected when not given. Language codes like en, tr, de, fr, es, ar, zh, or language names.
• GET/package—No price listedFacts about a package on npm, PyPI or crates.io: latest version and date, license, description, repository, maintainers (npm), weekly downloads (npm), a deprecated or yanked flag, and how many known vulnerabilities the latest version has (OSV).
• GET/books—No price listedBook lookup by ISBN (checked before the call) or by title and/or author: title, subtitle, authors, publishers, first publish year, median page count, ISBN-10 and ISBN-13 of the matching edition, languages, subjects, cover image URL, and the Open Library work and Wikidata ids. Data from Open Library (CC0). A title with no match is a 404, not charged. Up to 20 results.
• GET/exif—No price listedCamera make and model, lens, date taken, exposure (ISO, shutter, aperture, focal length), orientation, image size, software, and GPS latitude, longitude and altitude with a map link, from the EXIF of a JPEG, HEIC, TIFF or PNG image at a URL. Only the first 256 KB is read. A file that is not an image is 415; an image without EXIF is 200 with hasExif false.
• GET/ens—No price listedENS on Ethereum mainnet. A name (vitalik.eth) resolves to its address, and an address resolves to its primary name, accepted only when that name resolves back to the same address. Returns the avatar and the url, com.twitter, com.github, description and email text records when set. A name that is not registered returns 200 with address null.
• GET/evm/decode—No price listedFunction signatures for a 4-byte selector, and for calldata the decoded arguments. Signatures come from the openchain.xyz database, with 4byte.directory as fallback. Calldata is decoded against each candidate until one fits the selector and the arguments; bigints are returned as strings. Read-only.
• GET/pagespeed—No price listedGoogle PageSpeed Insights for one public URL: the Lighthouse scores (performance, seo, accessibility, best-practices), the lab Core Web Vitals (FCP, LCP, CLS, TBT, Speed Index), the CrUX field data when Google has it (LCP, INP, CLS), and the top five opportunities with estimated savings. Mobile by default. A run takes 10 to 40 seconds and is cached for an hour. Keyless calls share Google's quota, so a busy moment is a 503.
• GET/vulns—No price listedKnown vulnerabilities of one package version in the OSV database: npm, PyPI, crates.io, Go or Maven. Each advisory has its id, CVE aliases, summary, severity, fixed versions and a link. The count is the full number; up to 20 are listed.
• GET/evm/call—No price listedRead-only contract call (eth_call): decodes the return value of a function you name, e.g. balanceOf(address) returns (uint256). Nothing is signed or sent.

• GET/trackers—No price listedThird-party script and iframe hosts on a page, each classified (analytics, ads, tag manager, chat, session replay, social, consent, CDN), the cookies its first response sets (names and flags only, never values) and whether a known consent manager is present. Static HTML only: scripts added at run time are not seen.

Data lags by about a day; bots and unknown agents are excluded.
• GET/postcode—No price listedPlace names and coordinates for a postcode. GB adds district, ward and constituency (postcodes.io); other countries use Zippopotam.us for ZIP and postal codes. A postcode that does not exist answers 404, not charged.

Factors are exact to the definitions in NIST SP 811 (international inch and pound, US gallon, calorie IT, Btu IT, mechanical horsepower). An unknown unit is a 400 that lists every supported unit. Pure code, no outside source.
• GET/business-days—No price listedWorking days for a country. mode=between counts the working days after `from` up to and including `to` (up to 5 years) and lists the public holidays skipped; mode=add gives the date that is N working days after `date` (up to 3,650).

Fuzzy matching with aliases, transliteration and an optional country and date of birth to sharpen the score. Returns each possible match with its list, entry ID, score, programmes and official link. A screening aid, not a legal determination.

A venue that does not list the coin is left out and named in unavailable. Rates are as the venues publish them; funding is paid between traders, not to the venue. Information only, not financial advice.
• GET/defi/tvl—No price listedTotal value locked in DeFi from DefiLlama. For a protocol (its slug, e.g. aave-v3) the current TVL; for a chain (Base, Ethereum...) its TVL with 1-day and 7-day changes. A protocol's history is too large to read here, so it has no change figures. Attribution: Data: DefiLlama. Information only, not financial advice.
