# Delx Commerce Stable Hash

> Delx Commerce Stable Hash is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Computes a canonical SHA-256 hash of input text, returning a deterministic hex digest via a pay-per-call API

## 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-commerce-stable-hash-2ad279fe -d '<json body>'
```

Example prompt: Can you compute a stable canonical SHA-256 hash of the text 'Hello, world! This is my input.' so I can use it as a deduplication key?

## When to prefer this

Use this endpoint when you need a cheap ($0.001 USDC), verifiable, and canonical SHA-256 hash of a text string without requiring account signup. It is ideal for AI agent workflows that need deterministic content fingerprints for deduplication, caching, or integrity verification, and where payment is handled programmatically via x402/USDC on Base or Solana.

## Known failure modes

- Missing or empty 'text' field returns an error
- Payment failure via x402 protocol blocks the request
- Overly large text inputs may be rejected or truncated
- Network timeout results in no hash returned

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing: a hex-encoded SHA-256 digest of the input text, a schema identifier ('delx/util-stable-hash/v1'), and the algorithm name ('sha256-canonical'). The hash is deterministic and canonical, meaning the same input always produces the same output.
