MoneyTools Encode/Hash/Decode Utility
x402
MoneyTools Encode/Hash/Decode Utility is a paid API for AI agents from tools.moneytools.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-05).
Performs cryptographic hashing, encoding, decoding, and EVM-related transformations including sha256/sha1/sha512/md5/keccak256, HMAC-SHA256, base64, hex, URL encoding, JWT decode, function selector, and EVM checksum address.

How this service works
Catalog of MoneyTools: 115 cheap, read-only tools for AI agents. Free daily tier, then x402 USDC micropayments or prepaid credits. Token safety, approvals, tx decoding, EIP-712 risk, gas, ENS, x402 validation, DNS, RDAP, JSON Schema, time, FX.
Output
A JSON object containing the tool-specific result (e.g. hash hex string, encoded/decoded value, JWT payload, function selector, checksummed address) along with payment metadata including whether the free tier was used or a micropayment was charged, the network, amount in USD, and transaction ID.
Example use cases
EVM function selector for Solidity ABI
“What's the 4-byte function selector for 'transfer(address,uint256)'? I need it to build a raw EVM transaction.”
Decode JWT claims for debugging
“Can you decode this JWT for me and show me its header and payload claims — I don't need signature verification, just want to read the contents: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIn0.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c”
HMAC-SHA256 signing for webhook verification
“Compute an HMAC-SHA256 of the message 'order_id=42&status=paid' using the key 'mysecretkey123' — I need to verify a webhook signature.”

Endpoint
GEThttps://tools.moneytools.dev/v1/encode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, stateless cryptographic or encoding operations — especially for blockchain/EVM contexts (keccak256, function selectors, EVM checksum addresses) or standard web utilities (base64, JWT decode, HMAC). It covers a broad set of hash and encoding primitives in a single API, making it ideal for agents that need multiple transformation types without managing separate services. The micropayment model (x402 / USDC on Base) means no subscription required for low-volume use.
Side effects
- Missing required 'op' query parameter returns an error
- Unsupported operation name returns an error
- Invalid base64 or hex input when inputEncoding is set causes a decoding error
- Malformed JWT cannot be decoded
- Free tier exhausted (10/day per tool) results in HTTP 402 requiring x402 payment or API key
- Network or payment failure when x402 is required may block execution
