# Industrial Platform Web Tools – Hash (SHA-256/SHA-512/SHA-1/MD5)

> Industrial Platform Web Tools – Hash (SHA-256/SHA-512/SHA-1/MD5) is a paid API for AI agents from x402-gateway-production-1f21.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Computes a cryptographic hash (SHA-256, SHA-512, SHA-1, or MD5) for a UTF-8 text input and returns both hex-encoded and Base64-encoded digests.

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 industrial-platform-web-tools-hash-sha-256-sha-512-sha-1-md5-c23dd0e8 -d '<json body>'
```

Example prompt: Can you compute the SHA-256 checksum of the text 'Hello, world!' and give me both the hex and Base64 digests?

## When to prefer this

Choose this endpoint when an AI agent needs a fast, deterministic, machine-payable cryptographic hash of text without managing a local crypto library — especially useful in serverless agent pipelines, deduplication flows, or integrity verification steps where paying $0.001 USDC per call is preferable to provisioning compute. Supports four common algorithms in a single API.

## Known failure modes

- Missing required 'text' field returns a validation error
- Text exceeding 250,000 characters is rejected
- Invalid algorithm value (not sha256/sha512/sha1/md5) returns an enum error
- Non-UTF-8 or malformed body may cause a parse error
- Payment failure (x402) blocks the request before hashing occurs

## How this service works

Compute SHA-256, SHA-512, SHA-1 or MD5 checksum for UTF-8 text and return hex plus Base64 digests. Use for compute sha256 checksum, integrity verification, content fingerprints, cache keys, deduplication and agent pipelines.

## Output

Returns a JSON object containing the hex-encoded digest and Base64-encoded digest of the input text, along with the algorithm used. Both representations are suitable for storage, comparison, or further processing in agent pipelines.
