58 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
JWT decoder (no signature verification, nothing stored): header (alg, kid, typ), payload claims, human-readable iat/exp/nbf, whether the token is expired or not yet valid, seconds until expiry, and warnings such as alg=n...
Decode a transaction: send ?chain=base|arc&tx=0x... and get its event logs decoded (every ERC-20 and NFT transfer typed, with from, to and amount), the function called, success or failure, gas in USD and one plain-Englis...
Live block height, gas price and fee estimates (transfer, ERC-20 transfer, contract call) for Base or Arc. On Arc fees are quoted directly in USDC.
Generate a SHA-256 cryptographic hash from UTF-8 text
Base64 encode or decode text in one GET, with URL-safe output and the byte counts. Returns result, action, bytes, result_chars and sha256. Decoding accepts standard and URL-safe alphabets with or without padding and retu...
Base64 encode/decode with auto-detection: valid base64 input is decoded (UTF-8), anything else is encoded; force with 'encode:' or 'decode:'. Also returns URL-safe base64 and hex. $0.01 per call.
Plain-language explanation of an EVM transaction by hash across 12 networks: net token movements per participant (ERC-20, ERC-721, ERC-1155, native, WETH), the operation type (swap, transfer, approve, mint, deploy, wrap,...
ABI-encode a function call (selector + args) or encode/decode arbitrary ABI types — build and parse EVM calldata correctly.
Read a contract's recent event logs on an EVM network over a bounded block window and decode them. Logs are decoded from an event signature you supply, or from the contract's verified ABI, or by resolving the topic to a...
Reverse a 4-byte function selector, an event topic hash, or raw calldata into its human-readable signature using the 4byte database, with collisions resolved so the real signature (the oldest registered) is returned firs...
