## 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 csv-import-gate-offline-typed-contract-checker-e7ab5c07 -d '<json body>'
```

Example prompt: I need to buy that offline CSV contract checker Python toolkit from Speedbot — use my email dev@example.com, generate a checkout key and request ID, and confirm I consent to digital delivery.

## When to prefer this

Choose this endpoint when you need a self-contained, offline Python toolkit to validate CSV inventory or catalog files against a JSON contract before import, with no runtime dependencies. Prefer it over live API validators when the validation must run offline or in air-gapped environments, and over generic CSV parsers when you need explicit contract enforcement rather than simple format checking.

## Known failure modes

- Invalid or missing email format returns a validation error
- checkout_key not exactly 64 hex characters causes rejection
- request_id shorter than 16 characters or missing causes failure
- digital_delivery_consent not explicitly set to true blocks purchase
- Duplicate request_id on a new purchase attempt may conflict — retain original on retries
- Insufficient USDC balance causes payment failure
- Network or facilitator timeout during x402 payment flow
