## 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-title-case-converter-1468b151 -d '<json body>'
```

Example prompt: Can you convert this to title case: 'the quick brown fox jumps over the lazy dog'?

## When to prefer this

Choose this endpoint when you need a simple, deterministic title case conversion with no authentication setup, no API keys, and pay-only-when-you-use-it pricing via USDC on Base or Solana. Ideal for agents that process occasional text formatting tasks without committing to a subscription service. Best when verifiable delivery and micropayment billing per call are important.

## Known failure modes

- Input text exceeds 100,000 character limit — request rejected
- Malformed JSON body or missing 'text' field — 400 error
- Payment failure via x402 (insufficient USDC balance or unsupported chain) — 402 error
- Empty string input may return empty or trivially formatted result

## How this service works

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

## Output
