## 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-text-reverse-b91c197f -d '<json body>'
```

Example prompt: Can you reverse the text 'delx' for me so I can see what it looks like backwards?

## When to prefer this

Choose this endpoint when you need a simple, verifiable, pay-per-use text reversal with no signup or API key required. Ideal for agent workflows that need a trustless, auditable utility call settled in USDC on Base or Solana via the x402 protocol. For high-volume or free usage, a local string reversal implementation is more practical.

## Known failure modes

- Missing or empty 'text' field returns an error
- Non-string input types may cause validation failure
- Payment failure via x402 protocol blocks execution
- Network timeout if Base/Solana payment rails are congested

## How this service works
