Repository, build, lint, test and code-understanding services that an agent can call while working in a codebase.
Computes weighted pass rates and weighted scores from caller-labeled test outcomes, with deterministic category summaries. It does not run tests, validate labels, measure untested capabilities or establish deployment saf...
QR code generator. Returns a crisp SVG for text/URL payloads up to 2,048 UTF-8 bytes that fit the selected error-correction level.
npm package facts: latest version, license, weekly downloads, deps, types, deprecation — Genesis402 / UnyKorn Operator Network
Providers each build their signing string differently — some sign only the body, others prepend a timestamp, an id, or a version marker in a fixed order — and getting that order wrong produces a mismatch that looks exact...
Generate a PNG QR code URL for payment and onboarding payloads (upstream probed live)
Decode a GS1 element string (POST body { data }).
QR code generator: turn any text or URL (up to 2000 characters) into a scannable PNG QR code, generated on our own hardware in milliseconds, returned base64. Answers "make me a QR code for this link." Set size 128-1024px...
Guess the character set of a base64-encoded byte buffer: sniffs a byte-order mark, then falls back to ASCII / UTF-8 validation and a UTF-16 NUL-pattern heuristic. Returns a best-effort charset with a confidence label — a...
Format a numeric amount as currency for a given locale using Intl, honouring the currency's own minor-unit convention (USD→2, JPY→0). display selects the symbol, narrow symbol, ISO code or full name. An unknown currency...
Decode a base64 byte buffer from one character set and re-encode it into another (utf-8, utf-16le, utf-16be, latin1, ascii). Characters that the target set cannot represent, or bytes invalid for the source set, are clean...
Resolve a single code point (given as 'char' or 'codepoint') to its name, general category, block, script and plane. Provide exactly one of the two inputs.
Generate a PNG QR code URL for payment and onboarding payloads (upstream probed live)
Get the verified Solidity/Vyper source code for a deployed contract by address, sourced from Sourcify. Returns every source file (path + content), the contract name, language, compiler version and compiler settings (opti...
QR code generator. Generate a QR code for a URL or any text (UTF-8, up to 1,000 characters) as a scalable SVG plus a ready-to-embed data URL, at error correction L, M (default), Q or H. Use to put a link, Wi-Fi string or...
Morse code translator. Translate text to international Morse code (letters separated by spaces, words by /) or Morse code back to text; the direction is detected automatically or set with mode. Letters, digits and common...
Caesar cipher, ROT13. Encode or decode text with a Caesar cipher: every letter A-Z shifted by 1-25 places (13, the default, is ROT13), case kept, digits and punctuation untouched. decode=true shifts back. Use for puzzles...
Decode EVM transaction input data: looks up the 4-byte function selector and decodes every argument (addresses, amounts, arrays). Use to see what a transaction or signing request will really do.
Read a raw storage slot of any contract (eth_getStorageAt), also decoded as uint and address. Use for proxy slots, packed variables and debugging.
Check whether a Base mainnet address is a contract via eth_getCode - returns bytecode size, zero for an externally-owned account.
Convert text between utf-8, base64, hex, URL-percent-encoding and ascii representations.
Resolve a BIC/SWIFT code (8 or 11 chars) into the underlying bank: name, country, city, LEI, and registered head-office address (where available). Use only when you already have the BIC — for IBAN inputs, prefer /v1/iban...
Transaction details and receipt by hash: status, block, from, to, value, gas used, effective gas price and decoded ERC-20 transfers.
Run local cryptographic utilities: SHA-256 and SHA-512 hashes, Base64 encode/decode, or a random UUID v4. No upstream service is called.
Rust crate upgrade brief between two versions of a crates.io crate (tokio, clap, rand, serde): removed and changed Cargo features, default feature changes, dependency requirement diff, rust-version (MSRV) and edition cha...
