## 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 brian-booms-x402-catalog-query-840ab9bf
```

Example prompt: Show me the full catalog of Brian Booms agent packs available for micropurchase — I want to see everything from the impulse tier to the premium packs with pricing in JSON format.

## When to prefer this

Use this endpoint when an agent needs to discover what content packs or music licenses are available for micropurchase via x402 on Base before committing to a payment. Prefer it over navigating brianbooms.com directly when you need machine-readable JSON catalog data suitable for programmatic downstream purchasing decisions.

## Known failure modes

- Missing or invalid format parameter may return an error or non-JSON response
- Payment required (HTTP 402) if the catalog endpoint itself requires a $0.02 USDC micropayment before returning results
- Catalog may be empty or unavailable if the service is down
- Response schema is loosely typed (type: json) so structure may vary across versions

Agent micropay is NOT a DistroKid or Gumroad order; humans buy Worthy mug via DistroKid print-on-demand. V3.6: automated fulfillment (instant license certificates, member tokens), $0.99 impulse tier, agent-only micro-store ($0.02-$0.25) at /api/v1/agent-store/.
