## 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-soundex-encoder-ff0ee43a -d '<json body>'
```

Example prompt: What's the Soundex code for the name 'HELLOAGENTWORLD'?

## When to prefer this

Choose this endpoint when you need a deterministic, pay-per-call Soundex phonetic encoding with no signup overhead, verifiable delivery, and micropayment settlement in USDC. Ideal for agents that need on-demand phonetic normalization without committing to a subscription or managing API keys.

## Known failure modes

- Empty or missing 'text' field returns an error
- Text exceeding 100,000 characters is rejected
- Non-alphabetic-only inputs may produce unexpected or minimal Soundex codes
- Payment failure via x402 protocol blocks the request
- Network timeouts or service unavailability return HTTP 5xx errors

## 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 the computed Soundex code (e.g. 'H425'), the uppercased input text, and a schema identifier ('delx/soundex/v1') confirming the encoding algorithm used.
