61 x402 pay-per-call tools that chain: each answer names the next call. No API key, no account.

Registration data for one domain, read from the registry's own RDAP service through the IANA bootstrap — not scraped from port-43 whois text. Returns creation, expiry and last-change dates, age and days to expiry, registrar, EPP status codes, nameservers, DNSSEC and the abuse contact. TLDs with no RDAP server say so instead of reporting the domain as unregistered. No API key, no account.

Turns a Solidity signature like transfer(address,uint256) into its 4-byte function selector and its 32-byte event topic0. What you need to build calldata by hand or to filter logs.

One lighthearted developer roast aimed at a target YOU choose - javascript, python, css, git, regex, kubernetes, agile or legacy code - and at the severity you ask for. Every other roast endpoint returns something generic; this one lets a code-review agent roast the actual stack in front of it. Bilingual, seedable and repeat-free.

Generates an illustration from a text prompt with DreamShaper 8 LCM in about 2 seconds: painterly and character art rather than photoreal. Takes a seed for a repeatable result, a negative prompt, and your own width and height. Returns a hosted image URL valid for 24 hours; add inline=true to also get the base64. You are only charged if the image is delivered. No API key, no account.

Checks one crypto address against the OFAC SDN list published by the US Treasury, across 16 currencies including Ethereum, Bitcoin, Tron and USDT. A hit returns the actual list entry - sanctioned entity, its type and its sanctions programmes - not a risk score. Exact matching only, never fuzzy. Every answer carries the publication date of the list snapshot. No API key, no account.

Converts an amount between any two of the ~30 currencies in the European Central Bank's official reference rates, on today's publication or on a past date within the last 90 days. Returns the rate used, its publication date and whether it was crossed through the euro. This is the auditable rate accounting and customs ask for, not a live market quote: it is published once a day and it is reproducible.

Current conditions for any point on Earth, taken from the Norwegian Meteorological Institute's official forecast model rather than a commercial aggregator. Returns temperature, humidity, pressure, wind speed and bearing, cloud cover and the next hour's precipitation, plus the exact model run it came from and the units the institute itself declares, so the figure can be cited and checked instead of merely trusted.

Spot price of any ERC20 read straight from the deepest Uniswap V3 pool against USDC, on Base, Ethereum, Polygon, Arbitrum or Optimism. Returns the pool address, fee tier, liquidity, sqrtPriceX96, tick and block, so the number can be audited instead of trusted. No aggregator and no API key: the source is the chain itself. Via eth_call.

Day-by-day forecast for any point on Earth, up to nine days out, from the Norwegian Meteorological Institute's official model rather than a commercial aggregator. Each day carries its minimum and maximum temperature, total precipitation, strongest wind and the midday symbol, together with the exact model run and the institute's declared units, so a planning decision can cite where the number came from.

Turns a document into clean Markdown in about a second: pass an https URL or base64 of a PDF, Word, Excel, PowerPoint, HTML, CSV or XML file and get the text back with its headings, tables and page markers, plus the token count. It reads the text layer, so a scanned page with no text layer comes back without text. You are only charged if the Markdown is delivered. No API key, no account.

Edits an image you provide instead of generating one from scratch: pass the image and a black-and-white mask, and Stable Diffusion inpainting repaints only the white area following your prompt. Image and mask go as https URLs or as base64, up to 10 MB each. Returns a hosted image URL valid for 24 hours. You are only charged if the edit is delivered. No API key, no account.

Transcribes an audio file with Whisper large v3 turbo: pass an https URL (mp3, wav, flac, m4a, ogg, up to 10 MB) or base64 audio in a POST. Returns the text, the detected language with its probability, the duration, and timed segments; add words=true for word-level timestamps. Around 100 languages. You are only charged if the transcript is delivered. No API key, no account.

Translates text between about 100 languages with Meta M2M100 1.2B: pass the text and the target language (ISO code like es, fr, de, zh, ja, or its English name); the source language is detected if omitted. Long texts are split by sentence, so paragraphs keep their order and line breaks. Up to 2000 characters per call. Pairs with speech-to-text: translate a transcript, then read it aloud. You are only charged if the translation is delivered. No API key, no account.

Every currently valid TLS certificate publicly issued for one domain, read from the Certificate Transparency logs: issuer, validity window, days to expiry, revocation status and every hostname each certificate covers. It reports what was ISSUED, which is how you find certificates you did not know existed - not what the server is serving today. No API key, no account.

One-call verdict on any ERC20 on Base, Ethereum, Polygon, Arbitrum or Optimism: a machine-readable label for who can act on your balance (no-owner-powers, owner-can-intervene, owner-controls-balances, not-a-token), a headline, a plain-language reading and a paste-ready card - with the deterministic evidence underneath, selector by selector. Label, score and card come from the deployed bytecode and live state, never from a model. Research, not investment advice.

Describe a job in plain words and it gets done in ONE paid call: picks the right tools from 71 capabilities - transcription, translation, documents, images, web, on-chain, domains, IPs, weather, FX - fills their parameters and chains up to 3 steps, feeding each result into the next. Priced per job: the 402 challenge quotes YOUR job before you sign, from $0.02. You pay for not having to know which tool or which order. If nothing fits, nothing is charged.
