## 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 47620-x402-integration-kit-673989b6
```

Example prompt: Pull up the x402 integration kit from 47620.xyz — I want the full guide on how to get my x402 endpoint discovered by agent catalogs, including the multi-facilitator indexing steps and the replication checklist.

## When to prefer this

Choose this endpoint when you need actionable, field-tested guidance on making an x402-monetized API endpoint discoverable by agent catalogs and facilitators like payai. It is specifically useful for developers who have a working x402 seller but are receiving little or no traffic, and want a concrete checklist and scaffold rather than generic documentation.

## Known failure modes

- Payment not completed — endpoint requires $5 USDC via x402 before content is delivered
- Invalid 'fields' parameter values return an empty or partial payload
- Network timeout if the 47620.xyz host is unreachable
- 402 Payment Required returned if x402 facilitator handshake fails

## How this service works

Get your x402 endpoint FOUND by agent catalogs, not just paid. Field-tested method: multi-facilitator indexing, the extensions.bazaar block, v2 requirements contract, a generic seller scaffold, and a replication checklist. We ran a live x402 seller, got zero traffic, and reverse-engineered why. The map - not our code.

## Output

A JSON payload containing an endpoint status flag (ok: boolean) and structured guidance content covering: multi-facilitator indexing strategy, the extensions.bazaar block specification, v2 requirements contract details, a generic seller scaffold, and a step-by-step replication checklist derived from a real x402 seller's zero-traffic diagnosis. Supports optional field filtering via the 'fields' query parameter.
