Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 one-engine-number-analysis-pack-tier-6-017a3d9a -d '<json body>'
```

Example prompt: Run a tier 6 number analysis on the value 42 and tell me what result comes back.

## When to prefer this

Choose this endpoint when you need low-cost ($0.0035 USDC), pay-per-call numeric analysis specifically at tier 6 processing level, integrated with x402 micropayment protocol on Base. Prefer it for autonomous agent pipelines that need deterministic per-call billing without subscriptions.

## Known failure modes

- Missing or invalid 'value' field returns an error response
- Non-numeric input rejected by schema validation
- Payment failure via x402 prevents call execution
- Cloudflare Worker timeout or unavailability returns 5xx
- Ambiguous or null numeric value may return unexpected tier output

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object containing 'tier' (integer, value 6) and 'result' (a tier-dependent analytical output whose form depends on the tier logic — could be a classification, score, or derived value).
