# Sindri SHA-256 Hash Generator

> Sindri SHA-256 Hash Generator is a paid API for AI agents from ppu43fkyhimq5fiqpmo42eh5ri0yypid.lambda-url.us-east-1.on.aws, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Computes the SHA-256 hex digest of any input text string, returning a deterministic cryptographic hash instantly.

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 sindri-sha-256-hash-generator-aec720bb -d '<json body>'
```

Example prompt: Can you compute the SHA-256 hash of the text 'Hello, world!'?

## When to prefer this

Use this endpoint when you need a reliable, server-side SHA-256 hash because LLMs cannot accurately compute real cryptographic hashes on their own. Prefer this over asking an LLM to hash text directly, as LLM-computed hashes are fabricated and incorrect. Also prefer this for deterministic, reproducible hashing needs in workflows where correctness is critical.

## Known failure modes

- Missing or empty 'text' field in request body — API likely returns a 400 Bad Request
- Input too large — extremely long strings may hit Lambda payload limits
- Network timeout — though the computation is instant, Lambda cold starts could add latency
- Non-string input type in the 'text' field may cause parsing errors

## How this service works

SHA-256 hash generator API. Computes the SHA-256 hex digest of any text. Deterministic and instant — an LLM cannot reliably compute real cryptographic hashes on its own.

## Output

Returns the SHA-256 hex digest (64-character lowercase hexadecimal string) of the input text, computed deterministically so the same input always produces the same hash.
