## 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 x402-tools-cohort-pass-diagnostic-endpoint-1396a15a
```

Example prompt: Can you test the x402 cohortpass paid diagnostic endpoint for me — I want to confirm the EIP-3009 USDC payment flow is working correctly with the OpenX402 facilitator and get back the cohort pass confirmation payload?

## When to prefer this

Choose this endpoint when you need to verify that an x402 micropayment integration — specifically EIP-3009 USDC authorization through the OpenX402 facilitator — is functioning end-to-end. It is purpose-built as a diagnostic tool for the cohortpass SKU, not a production data source. Prefer it over generic HTTP testing tools when you specifically need to exercise and validate x402 protocol payment gating behavior.

## Known failure modes

- HTTP 402 returned with EIP-3009 extras when no valid USDC payment authorization is provided
- Payment facilitated by a non-OpenX402 facilitator is rejected
- Malformed EIP-3009 signature causes authorization failure
- Insufficient USDC balance leads to payment failure and 402 response
- Network or endpoint unavailability returns 5xx errors

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

A JSON object containing the SKU name ('cohortpass'), a diagnostic note clarifying it is a paid example shape, the price ('$0.20'), and the title ('Cohort Pass'). Unpaid or improperly authorized requests receive HTTP 402 with EIP-3009 extras instead.
