Base URLhttps://flat-rate-llm.kikoribera03.workers.dev/v1

• GET/content/roast—No price listedOne 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.
• GET/content/word-of-the-day—No price listedThe word of the day with its definition, part of speech and an example sentence, in English or Spanish. Genuinely of the day: it is picked deterministically from the UTC date, so everyone gets the same word and you can reproduce any past day by passing it. The usual endpoints just return a random word and call it the word of the day.
• GET/do—No price listedDescribe 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.
• GET/evm/balance—No price listedNative coin balance (ETH, MATIC...) for any address, on Base, Ethereum, Polygon, Arbitrum or Optimism. Flat price, no rate limits, no API key. Via eth_getBalance.
• GET/red/domain-check—No price listedEverything DNS says about one domain in a single call: whether it is registered, its A and AAAA addresses, nameservers, MX servers, SPF and DMARC, DNSSEC, and whether it looks parked. Built for going through a list of domains one at a time. Live DNS, no API key, no account.
• GET/evm/token-info—No price listedName, symbol, decimals and total supply of any ERC20 contract in one call. Useful to label a token address before showing it to a user. Via eth_call.
• GET/random/dice—No price listedRoll dice with any number of faces and get every roll plus the total. Uses the platform CSPRNG with rejection sampling, so every face is equally likely - a plain modulo is biased. Standard dice notation: 3d6, 1d20.
• GET/ai/image-edit—No price listedEdits 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.
• GET/util/vat—No price listedValidates one EU VAT number offline: country prefix, the format that country uses, and the published check-digit algorithm where one exists. Says explicitly whether the check digits were verified or only the format. Deterministic, no network call. Built for cleaning a list of companies one at a time.
• GET/util/units—No price listedConverts between wei, gwei, ether and any token decimals using exact integer maths - no floating point, no silent rounding. The mistake that costs real money is being off by a thousand on decimals.
• GET/weather/forecast—No price listedDay-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.
• GET/util/base64—No price listedBase64 in both directions, including the URL-safe alphabet, with UTF-8 handled properly. Encoding is what carries payloads through headers and JSON, and x402 itself rides on it.
• GET/evm/fees—No price listedSuggested maxFeePerGas and maxPriorityFeePerGas from the last 20 blocks of real fee history, at slow, normal and fast percentiles. Beats guessing a gas price and getting stuck in the mempool. Via eth_feeHistory.
• GET/web/status—No price listedChecks one URL without downloading the page: HTTP status, the full redirect chain hop by hop with the code of each, the final URL, whether it ends on HTTPS, content type and size, and the security headers the server sends. Built for going through a list of links one at a time. No API key, no account.
• GET/random/number—No price listedUniform random integers in any range you give, with or without repeats. Rejection sampling, so the ends of the range are not slightly less likely - which is what happens with modulo.
• GET/evm/nonce—No price listedNext transaction nonce for any address, and whether the address is a contract. What an agent needs before signing a transaction. Via eth_getTransactionCount.
• GET/ai/document—No price listedTurns 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.
• GET/evm/portfolio—No price listedNative balance plus the balance of every token you list, on one chain, in a single paid call - each with symbol and decimals already applied. One request instead of one per token. Via eth_getBalance + eth_call.
• GET/time/zones—No price listedSearch the full IANA time zone list and get each zone's current UTC offset, abbreviation, local time and DST state. Use it to turn a city or a country into the exact zone name the other endpoints expect, or to find every zone sitting at a given offset right now.
• GET/crypto/sanctions—No price listedChecks 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.
• GET/content/riddle—No price listedOne riddle by difficulty, in English or Spanish, with the answer AND the SHA-256 of the answer in lowercase. The hash is the point: an agent can check whether its guess is right without reading the solution first, which no other riddle endpoint lets you do.
• GET/util/address—No price listedValidates an EVM address and returns it in EIP-55 mixed-case checksum form. Catches typos before you send funds: an address that fails the checksum is almost always mistyped.
• GET/evm/ens—No price listedResolves an ENS name to its address, or an address back to its primary ENS name, reading Ethereum mainnet directly. Names are what humans paste and addresses are what chains need.
• GET/util/iban—No price listedValidates one IBAN offline: country, expected length, ISO 7064 mod-97 check digits, whether it is inside SEPA, and the account number split out. Deterministic, no network call and no third party that can go down. Built for cleaning a list of accounts one at a time.
• GET/evm/erc20-allowance—No price listedHow much of a token a spender is still allowed to move on an owner's behalf, and whether that approval is unlimited. The check to run before an approve, and the one that finds forgotten infinite approvals. Via eth_call (allowance).
