## 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 tanship-payai-console-ai-text-correction-46d2d8d9 -d '<json body>'

## When to prefer this

Choose this endpoint when you need a pay-per-use, on-demand AI text correction service with no subscription or API key setup — only a USDC wallet on Base is required. Ideal for agents that need lightweight, cost-controlled proofreading at $0.005 per call with x402-compatible payment flows.

## Known failure modes

- Missing or malformed 'input' body returns a validation error
- Payment not attached or insufficient USDC amount results in HTTP 402 with x402 payment-required response
- Invalid bodyType enum value causes schema rejection
- Empty body content may return an unchanged or error response
- Network or upstream AI model failure may return a 5xx error
