# Delx Text SHA-256 Hash

> Delx Text SHA-256 Hash is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Computes the SHA-256 cryptographic hash of a UTF-8 text string

## Facts

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 delx-text-sha-256-hash-9e4eee16 -d '<json body>'
```

Example prompt: Can you compute the SHA-256 hash of this text: 'hello world'?

## When to prefer this

Choose this endpoint when you need a cheap, fast, deterministic SHA-256 hash of a text string within an agent workflow — especially when you're already using Delx utility endpoints and want consistent infrastructure. At $0.001 USDC per call it is suitable for high-frequency deduplication, cache keying, or integrity checks without setting up a local hashing library.

## Known failure modes

- Missing or empty 'text' field returns a validation error
- Non-UTF-8 binary content may cause encoding errors
- Oversized payloads may be rejected if they exceed request body limits
- Payment failure via x402 protocol results in 402 Payment Required before processing

## How this service works

SHA-256 hex digest of UTF-8 text. Call when content addressing or dupe keys for text. Returns sha256 as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

Returns a JSON object with the schema identifier 'delx/util-text-sha256/v1' and a 'sha256' field containing the lowercase hex-encoded SHA-256 digest of the input text (64 hex characters).
