# Foundry Hash Generator

> 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

## Facts

- Endpoint: POST https://minty-sprout.onrender.com/v1/hash?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-11-01
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/foundry-hash-generator-85eed239
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_IfmWk9VBiAnH4zcDtwrm9

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability foundry-hash-generator-85eed239 -d '<json body>'
```

Example prompt: Can you hash the text 'hello world' and give me the SHA256, Keccak256, and MD5 digests all at once?

## When to prefer this

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.

## Known failure modes

- 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)

## 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.
