## 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 prompt-injection-triage-fencing-downloadable-toolkit-speedbot-99cffeb5 -d '<json body>'
```

Example prompt: I want to buy that Speedbot prompt-injection triage and fencing toolkit — use my email agent@example.com, generate a fresh checkout key and request ID, and confirm digital delivery consent so I get the ZIP right away.

## When to prefer this

Choose this endpoint when your agent pipeline ingests text it did not write — peer agent messages, inbound emails, buyer-uploaded files, or scraped web content — and you need a deterministic, dependency-free triage layer to detect and fence prompt-injection payloads before they reach your LLM. Prefer this over generic content moderation APIs when you specifically need prompt-injection semantics rather than hate-speech or spam filtering, and when offline/embedded operation (no runtime API dependency) is a priority.

## Known failure modes

- Missing or invalid email format — request rejected with validation error
- checkout_key not a valid 64-character hex string — payment refused
- request_id shorter than 16 characters or missing — request rejected
- digital_delivery_consent not set to true — purchase blocked
- Duplicate request_id on a retry without idempotency support — potential double-charge or rejection
- Payment insufficient or USDC transfer failure — order not fulfilled
- Network timeout before delivery URL returned — retry with same request_id and checkout_key
