Send a list of texts — website addresses, phone numbers, plain words, WiFi details, anything — and get back a ready-to-use QR code image for each one. Every QR code comes as a base64-encoded PNG you can drop straight into a webpage or save to disk. Great for marketing campaigns, event tickets, product labels, menus, or any situation where you need many QR codes in one go. Empty entries are quietly

Read the text out of a QR code or barcode in a PNG or JPEG image. Auto-detects QR, DataMatrix, PDF417, Aztec and 1D symbologies (Code128/39/93, EAN-13/8, UPC-A/E, ITF, Codabar). A valid image with no code returns { found: false }; a payload that is not a parseable image is a 400.

A styled QR code (module shapes, corner markers, a logo or a halftone photo) for any text, no account needed

Encode text into international (ITU) Morse code. Letters are separated by spaces and words by "/". Supports A-Z, 0-9 and common punctuation; unsupported characters are clean 400s.

Generate scannable QR codes from any text, URL, or structured payload (WiFi, vCard, SMS, email, geo, crypto). Returns PNG by default with JPG, WebP, and SVG output, plus optional error-correction, sizing, color, version, and encoding controls. Simple cURL POST: send qr_data, receive an image.

Verify output another AI agent hands back, by code alone, for $0.005: no model call, answers in about a second. Recomputes the deliverable's written sums, totals, percentages, dates, weekdays, time spans, unit conversions, and list counts; checks lengths the task asks for; flags placeholders and prompt injection; measures words, items, and JSON shape. Signed receipt, tier lite. For every requireme

Identicon generator — turn an exact UTF-8 seed into a deterministic mirrored avatar returned as base64-encoded SVG or PNG in JSON.

Resolve a Unicode block name (loose matching) to its range, size, count of assigned characters and a small sample. An unknown block is a successful `found:false`. This is a Unicode Character Database block — not a blockchain block.

Give this API a list of up to 10 web addresses and it will visit each one to tell you whether it is working, broken, or redirecting visitors somewhere else. You get back the exact status number (like 200 for OK, 404 for not found, 500 for server error), whether the address redirects, and where it redirects to. Great for finding broken links, verifying website migrations, and running quick SEO audi

Check Python for syntax errors, lint and type mistakes, unsafe constructs and hardcoded credentials, and against the examples the caller supplies, without running it.

Generate an RFC 6238 time-based one-time password from a base32 secret. Uses the current time by default, or an explicit unix timestamp (seconds); configurable period (default 30s), digits (default 6) and algorithm (default SHA1). Also returns the counter and seconds remaining in the window.

Screen a person, entity, vessel or aircraft name against the EU, UK, UN, OFAC (SDN and Consolidated), Swiss, Australian and Canadian sanctions lists, refreshed daily. Returns the matching sanctioned parties with match scores, programs, birth dates and list references, best match first; matches are name similarity and should be reviewed. No account, API key or subscription required; x402 clients ha

Offline structural validator for an Indian CIN (Corporate Identity Number, 21 characters). Parses and checks: listing status letter (L/U), 5-digit NIC industry code, 2-letter state code (against the known MCA state-code list), 4-digit incorporation year (plausible range), 3-letter company-type/ownership code (against a known enum like PLC, PTC, OPC, GOI, NPL, FTC, SGC, ULL, ULT), and 6-digit regis

Look up an active ISO 4217 currency by its alphabetic code or numeric code. Provide exactly one field. Returns the code, numeric code, name and number of minor units (decimal places).

Fuzzy-search airports by name, city or code, optionally filtered by ISO country code or airport type. Matches are ranked exact-code/name then prefix then substring, larger airports first. Empty result is a successful 200.

Check whether a postal / ZIP code is well-formed for a country (ISO 3166-1 alpha-2). A malformed code is a successful result with `valid:false`, not an error — only an unsupported country or empty code is a 400.

Pay $0.01 USDC to store up to 100 KB of text or code. Returns a token for free retrieval anytime via GET /paste/{token}. Network: Base Mainnet. Each request stores one text or code blob and returns a retrieval token, making it useful for notes, code snippets, logs, and debug-output sharing.

Country facts, $0.001 USDC per call: Reference facts for any of 250 countries/territories by ISO code or English name: common + official name, ISO alpha-2/alpha-3/numeric, capital, region/subregion, languages, currencies (code, name, symbol), calling codes, internet TLD, lat/lng, area km², bordering countries, landlocked, UN member, flag emoji, plus World Bank region and income level. No params =

AliExpress product search from the public search page: product ID, title, sale price and original price with currency code, discount %, promo label (welcome-gift cards have no price), star rating and units-sold text when shown, listing date, image and product URL; 60 products per page plus the total result count. Language and currency can follow the caller's region (the currency code is always ret

Active National Weather Service watches, warnings and advisories for a US coordinate or a two-letter state or marine area code - event, severity, certainty, urgency, headline, affected areas and zone codes, and effective/onset/expiry times in UTC. Read at request time, so an empty list means nothing is active. The 5 newest come back by default; detail=full adds the NWS narrative. Use when: Decide

EU public procurement tender notices from the official TED (Tenders Electronic Daily) v3 API, filtered by CPV product/service code, country of performance and free-text keywords over a recent publication window; returns structured JSON per notice with title, buyer, deadline, publication date, CPV codes, notice URL and German PDF link.

Signed attestation (ECDSA plus a post-quantum ML-DSA-65 companion) of on-chain wallet conditions across 37 chains: token balance, NFT ownership, EAS, Farcaster, view calls, ratio rules, account code (plain key, EIP-7702 delegation, or contract), and agent standing (ERC-8004 registration, ERC-7710 delegation validity). A verifiable boolean, never raw balances or code. Up to 10 conditions per pay-pe

Perfume batch/lot code decoder — estimates production date and freshness verdict from a bottle batch code, using an in-house deterministic decoder covering Coty, Estee Lauder-group, Chanel, LVMH/Dior-group, and L'Oreal Luxe house formats, with an explicit confidence tier (never false precision).
