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-seeded-color-hex-generator-737e4561 -d '<json body>'
```

Example prompt: Generate a consistent hex color for the seed string 'alice@example.com' — I need the same color every time for that user.

## When to prefer this

Choose this endpoint when you need a reproducible, deterministic hex color from a string seed with cryptographic evidence of computation and no data retention — ideal for agent workflows requiring auditable, pay-per-use color assignment without standing API keys or subscriptions. Prefer over random color generators when consistency across calls matters.

## Known failure modes

- Empty or missing seed field — may return validation error
- Seed exceeding 8192 characters — rejected with input too large error
- Payment failure or invalid x402 payment header — 402 Payment Required with no result
- Network timeout — no result returned, retry safe since idempotent
- Malformed JSON body — 400 Bad Request

## How this service works

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

## Output

A JSON object containing: a hex color code (e.g. '#671c49'), an accessibility_checked flag (boolean), the schema version, operation name, status ('pass'), and evidence metadata including whether input was retained (always false), the SHA-256 hash of the input, and the number of external calls made (always 0).
