Every agent-payable API.

Answers a question from the given text only (max 30,000 characters), with supporting quotes and their character offsets. Each quote is checked against the text and dropped if it does not occur in it. answerable is false when the text does not contain the answer. Model output: verify before relying on it.

Place 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.

Repairs broken JSON: markdown fences, comments, trailing commas, single quotes, unquoted keys, Python literals (True, False, None) and truncated endings. Pure code first; the model is asked once only when code cannot repair it. Optional JSON Schema check covers type, required, properties, items, enum, minimum, maximum, minLength, maxLength and pattern. Input max 1 MB.

Hashes of a text or base64 input (up to 1 MB): MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC-32, and HMAC-SHA-256 or HMAC-SHA-512 when a key is given. Hex and base64 output. MD5 and CRC-32 are implemented here and checked against RFC 1321 and the standard CRC test vector. Body { input, encoding, algorithms, key }. Pure code and WebCrypto, no outside request.

Book 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.

Hacker News stories or comments from the Algolia search API: keyword search (q) or the current front page (mode=front), optionally since a date. Stories give title, URL, HN link, points, comments, author and time. Comments give their text (400 characters, HTML stripped) and the story title. Up to 50 results. Public data, no key.

Subdomains of a domain seen in certificate transparency logs: each name with the first and last certificate dates, the issuer of the newest certificate, and wildcard entries flagged. Deduplicated, newest first, up to 500. CertSpotter is read first, but its free index is partial, so those answers are marked truncated with the reason; crt.sh is the fallback and is complete. Only public certificates are listed.

Trending, newest, top-traded or top-organic Solana tokens (Jupiter) filtered by liquidity and 24h volume: price, market cap, liquidity, holders, volume, trades, price change, organic score, mint and freeze authority, top-holder share, age and red flags for each. Information only, not financial advice.

Fetches a site's security.txt from /.well-known/security.txt (fallback /security.txt) and parses the RFC 9116 fields: contacts, expiry (and whether it has expired), encryption, policy, acknowledgments, languages, canonical, hiring. Reports whether it is PGP-signed and lists RFC problems found. Public http(s) hosts only.

Readability of a text in pure code: Flesch Reading Ease, Flesch-Kincaid grade, Gunning Fog, SMOG, Coleman-Liau and ARI, with counts of characters, words, sentences, syllables and complex words, and reading and speaking time. English formulas; other languages get counts only. Syllables are counted by a vowel-group heuristic, so scores are estimates. Up to 100 KB.

Safety check of a text or a chat turn with Llama Guard 3: safe or unsafe, and the violated categories (S1 to S14, named in plain words). Send text, or messages (up to 20 turns). Classifies only; it does not change or block anything.

Read one web page as clean Markdown (or plain text) for an LLM: the main content without menus, cookie banners and footers, plus title, description, author, published date, language and canonical URL; links on request. robots.txt is respected (a disallowed page is refused and not charged). No JavaScript is run.

Website audit in one call: WCAG 2.2 accessibility issues (European Accessibility Act) with fixes and a score, SEO basics, security headers and tech stack.

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.

Cabin, maximum stops and market (sets the currency) are optional. Fares for a single traveller from Ignav; a fare search, not a booking.

Converts raw HTML you send (up to 500 KB) to GitHub-flavoured Markdown: headings, paragraphs, links, images, lists, code blocks, quotes, bold and italic. Scripts, styles, navigation, footers, forms and comments are removed; tables are flattened to text. Relative links need a base URL to become absolute.

Screens one message (DM, email or chat text) for common crypto and phishing scam signals in English: urgency, fake support or giveaway, wallet-connect or seed-phrase requests, guaranteed returns, and suspicious links. Returns HIGH/MEDIUM/LOW/NONE with each matched phrase. A fixed rule list: it misses new wording and other languages, and it never sees the sender's account.

Does not pay, does not verify the seller's identity or reputation, and gives one sample, not uptime.

Validates an IBAN (MOD-97 checksum and country length, computed here) and, if it passes, looks up the bank name, city and BIC (SWIFT) through OpenIBAN's public validation. The bank lookup depends on OpenIBAN's directory and may be missing for some banks; a valid checksum does not prove the account exists.

DNSSEC status for a domain using Cloudflare's public resolver (1.1.1.1 DNS-over-HTTPS): whether the resolver validated the answer (AD flag), the DS records in the parent zone, and the DNSKEY records with key-signing keys.
