## 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 first-attempt-delivery-share-named-scenario-comparison-f007e5fc -d '<json body>'
```

Example prompt: Compare two delivery scenarios for me: my baseline is 500 attempted shipments with 435 first-attempt deliveries. Scenario A is 550 attempted shipments with 480 first-attempt deliveries, and Scenario B is 500 attempted shipments with 460 first-attempt deliveries — show me how the first-attempt delivery share compares across all three.

## When to prefer this

Choose this endpoint when you need a quick, cost-effective what-if analysis for first-attempt delivery share KPIs using your own retail figures — especially when comparing named scenarios against a known baseline without needing live order data, platform access, or real-time rates. Ideal for logistics planning, carrier benchmarking, and operational efficiency modeling with up to 20 named scenarios per call.

## Known failure modes

- Validation error if scenarios array is empty or exceeds 20 items
- Error if attempted_shipments is zero or negative (exclusiveMinimum enforced)
- Error if first_attempt_deliveries exceeds attempted_shipments (logical inconsistency)
- Missing required fields (attempted_shipments or first_attempt_deliveries) in baseline returns 400
- Payment failure if 0.01 USDC is not supplied via x402 protocol
- Label exceeding 80 characters rejected
