Foundry Hash Generator
x402
Foundry Hash Generator is a paid API for AI agents from minty-sprout.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-01).
Computes multiple cryptographic hashes (MD5, SHA1, SHA256, SHA512, SHA3-256, BLAKE2b, Keccak256) of any input text in a single call

How this service works
Hash generator: md5, sha1, sha256, sha512, sha3-256, blake2b and keccak256 of a text. Input: any text.
Output
A JSON object containing the 'hashes' field with seven hash values (md5, sha1, sha256, sha512, sha3_256, blake2b, keccak256) all computed from the input text, plus 'input_bytes' indicating the byte length of the input string.
Example use cases
Ethereum smart contract input hashing
“I need the keccak256 hash of the string 'Transfer(address,address,uint256)' — can you compute it for me?”
Data integrity fingerprinting
“Generate the SHA256 and MD5 checksums of this text so I can verify it hasn't been tampered with: 'The quick brown fox jumps over the lazy dog'”
Security audit hash comparison
“What's the SHA512 hash of the password 'P@ssw0rd123!' — I want to compare it against a stored digest in our database”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need multiple cryptographic hash formats simultaneously from a single API call — especially when you need Keccak256 for Ethereum/EVM compatibility alongside standard hash algorithms like SHA256 or MD5. It saves multiple round-trips compared to calling separate hashing utilities and is ideal for lightweight text hashing tasks without needing a local cryptography library.
Side effects
- Input text exceeds 8000 character limit — request rejected
- Missing or empty 'input' field — likely returns validation error
- Network timeout if the Render.com server is cold-starting
- Payment failure if x402 USDC balance is insufficient (cost: $0.001 per call)
