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

• GET/v1/evm/receipt—No price listedReceipt of a transaction: whether it succeeded or reverted, gas used, fee actually paid, and how many logs it emitted. The call that answers did my transaction work. Via eth_getTransactionReceipt.
• GET/v1/evm/token-safety—No price listedPre-trade risk check for any ERC20 on Base, Ethereum, Polygon, Arbitrum or Optimism, straight from the deployed bytecode and live state. Detects mint, pause, blacklist, upgradeable proxy and mutable buy/sell tax powers, and reports whether ownership is renounced. Unlike LLM-written verdicts this returns the EVIDENCE - the exact selector found and its byte offset - so an agent can apply its own policy. Deterministic: same contract, same answer.
• GET/v1/evm/estimate-gas—No price listedEstimates the gas a transaction would need and prices it at the current gas price, before you sign anything. Also the cheapest way to find out that a call would revert. Via eth_estimateGas.
• GET/v1/content/joke—No price listedOne random joke, in English or Spanish, filtered by category: programming, crypto or general. Unlike the usual one-liner endpoints this one takes parameters, returns an id so you can exclude what you have already seen, and accepts a seed for a reproducible answer.
• GET/v1/util/keccak256—No price listedKeccak-256 of any string or hex payload - the hash Ethereum actually uses, which is NOT the same as SHA3-256. Needed for selectors, event topics, salts and CREATE2 addresses.
• GET/v1/red/ip—No price listedLooks up one IPv4 or IPv6 address against the two authoritative, keyless public sources: RDAP registry data (who holds the block, in which country, since when, abuse contact) via the ARIN-to-RIR referral chain, and the origin ASN from Team Cymru's DNS service. No city-level geolocation and no VPN/proxy detection — those need a licensed commercial database this endpoint deliberately does not use. Built for going through a list of IPs one at a time.
• GET/v1/util/uuid—No price listedCryptographically random UUID v4s, up to 100 per call, straight from the platform CSPRNG. For idempotency keys, request ids and correlation ids - the ones that must not collide.
• GET/v1/evm/block—No price listedLatest block height and timestamp of any supported chain, plus how old the chain head is in seconds. Tells an agent whether a node is in sync. Via eth_getBlockByNumber.
• GET/v1/evm/erc20-balance—No price listedERC20 token balance for any wallet - USDC, USDT, DAI or any token - via balanceOf. Returns the raw amount and the decimals so you can format it. Via eth_call (balanceOf).
• GET/v1/util/hex—No price listedConverts between hex, decimal and UTF-8 text in one call, with big integers handled exactly. For reading raw RPC output, which comes back as hex and overflows a JavaScript number.
• POST/mcp—No price listedMCP server exposing 69 tools - LLM completion, read-only EVM tooling and pure crypto utilities. initialize and tools/list are free so any client or directory can enumerate the tools; only tools/call is charged, a flat $0.001 per call.
• GET/v1/ai/image—No price listedGenerates a 1024x1024 JPEG from a text prompt with FLUX.1 [schnell] in about 2 seconds. Returns a hosted image URL valid for 24 hours that you can hand straight to the next tool; add inline=true to also get the base64. Choose 1-8 diffusion steps (default 4). You are only charged if the image is delivered. No API key, no account.
• GET/v1/evm/is-contract—No price listedTells whether an address is a smart contract or a plain wallet, and how big its bytecode is. A cheap safety check before sending funds. Via eth_getCode.
• POST/v1/ai/image-describe—No price listedDescribes what is in an image in about one second: pass an https URL or base64 and ask anything about it, from a one-line caption to reading a sign. Pairs with the rest of the chain: describe an image, translate the description, then have it read aloud. You are only charged if the description is delivered. No API key, no account.
• GET/v1/util/selector—No price listedTurns 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.
• GET/v1/content/advice—No price listedOne piece of practical advice about work, life or money, in English or Spanish. Short, concrete and usable - not a fortune cookie. Filterable by topic, with an id to avoid repeats and a seed for reproducibility.
• POST/v1/ai/transcribe—No price listedTranscribes 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.
• GET/v1/fx/convert—No price listedConverts 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.
• GET/v1/random/shuffle—No price listedShuffle a list into a uniformly random order with Fisher-Yates over the platform CSPRNG. Every permutation is equally likely, which sorting by a random key does not give you.
• GET/v1/red/email-check—No price listedScores one email address 0-100 with a verdict (ok, risky, disposable, undeliverable, invalid) and the evidence under it: every point lost is itemised with the field that proves it. 12,141 disposable domains from two maintained open lists pinned to a commit, 4,897 free providers, 1,018 role names, typo fix (gmial.com > gmail.com), live MX/SPF/DMARC. No SMTP probe, no API key.
• GET/v1/weather/now—No price listedCurrent 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.
• GET/v1/ai/speech—No price listedTurns text into natural speech in English, Spanish, French, Chinese, Japanese or Korean in one or two seconds: Deepgram Aura-2 for English and Spanish, MeloTTS for the rest. Returns a hosted audio URL valid for 24 hours (MP3 for English and Spanish, WAV otherwise) plus its size; add inline=true to also get the base64. Up to 2000 characters per call. You are only charged if the audio is delivered. No API key, no account.
