## 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-sentence-case-converter-7e160cae -d '<json body>'
```

Example prompt: Can you convert this text to sentence case: 'THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG. IT WAS A BRIGHT COLD DAY IN APRIL.'

## When to prefer this

Choose this endpoint when you need a lightweight, no-signup, pay-per-use sentence-case conversion without integrating a full NLP library or text processing service. Ideal for agents that need verifiable, priced-per-call text normalization on Base or Solana via USDC, especially in contexts where consistent billing and no account management overhead matter.

## Known failure modes

- Text exceeding 100,000 characters will be rejected
- Missing or empty 'text' field returns a validation error
- Payment failure via x402 prevents processing
- Non-string input type may cause a schema validation error

## 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 the sentence-cased version of the input text, the schema identifier ('delx/sentence-case/v1'), and the source character length. The converted text has only the first letter of each sentence capitalized, with all other letters lowercased.
