## 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 novapath-seasonal-case-retrieval-8c5dd2a6 -d '<json body>'
```

Example prompt: Pull up seasonal case NPWD26-M03-12 from NovaPath — I need the full case including source records, all six tasks, teacher answer keys, and the worked model.

## When to prefer this

Use this endpoint when you need the complete materials for a single known seasonal case — including tasks, teacher answers, and worked model — and you already have the specific case ID. If you need to browse or discover cases without a known ID, use the collection retrieval or search endpoints instead. If you only need the worked model and learning objectives without full task sets, a sibling endpoint is more efficient.

## Known failure modes

- Invalid caseId format returns validation error — must match pattern NPWD26-(M01-M12|D01-D04|R01-R02|J01-J02)-(01-25)
- Case ID not found if the specified case does not exist in the 500-case pool
- Payment failure if USDC payment is not properly attached to the x402 request
- Network or server error from the Vercel deployment

## How this service works
