## 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 capi2-tiktok-campaign-notary-109c7033 -d '<json body>'
```

Example prompt: Before my agent launches this TikTok campaign with a $5,000 budget, run an authority check against the authority policy I have configured and give me a notarized receipt — the action is 'launch_campaign' and the evidence includes the campaign brief and budget approval docs.

## When to prefer this

Choose this endpoint when an AI agent needs to enforce governance policies before executing TikTok campaign actions, particularly when you need both a real-time approve/block decision AND a tamper-evident audit receipt. It is especially useful in agentic pipelines where autonomous spend or campaign changes must be validated against predefined authority limits and logged for compliance purposes.

## Known failure modes

- Missing or malformed 'action' object returns validation error
- Evidence array exceeding 20 items rejected
- Authority object misconfigured causes policy evaluation failure
- Payment not completed (x402) results in 402 response before processing
- Unknown action type may produce inconclusive decision
- Network timeout on the Cloudflare Worker edge

## How this service works

Programmable authority checks and tamper-evident receipts for autonomous agents, sold through sustainable x402 commerce.

## Output

Returns a JSON object with a 'decision' field (approve or block), a 'findings' array listing any policy violations or risk factors (each with a code like 'budget_above_authority'), a unique 'receipt_id' (prefixed 'tn_') serving as a tamper-evident audit record, and a numeric 'risk_score' (0-100) quantifying the risk level of the proposed action.
