## 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 open-horizon-machine-revenue-json-quality-decision-engine-3d14ebf9 -d '<json body>'
```

Example prompt: I have a batch of 50 vendor records in JSON format — can you run them through the Open Horizon quality decision engine and tell me which ones pass the buy-or-skip threshold with reason codes?

## When to prefer this

Choose this endpoint when you need automated, machine-verifiable procurement, vendor risk, or API QA decisions on batches of up to 500 JSON records, especially in agentic pipelines that require structured reason codes and evidence alongside verdicts. Prefer it over generic LLM-based analysis when you need deterministic, auditable output with x402-gated access control.

## Known failure modes

- Payment not provided or insufficient — x402 payment required before fulfillment
- Records array exceeds 500 item limit — request rejected
- Malformed or non-object items in records array — validation error
- Empty records array — no decisions returned
- Worker timeout for very large or complex record sets

## How this service works

Agent decision products for procurement, vendor risk, API QA and public-web buy-or-skip workflows. Strict x402 payment is required before fulfillment.

## Output

Returns a structured JSON object containing a decision verdict (buy or skip), machine-verifiable boolean, evidence supporting the decision, and reason codes for each submitted record in the batch.
