## 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 apexscout-agent-commerce-reliability-ledger-1c1718ef
```

Example prompt: Pull up the ApexScout Agent Commerce Reliability Ledger so I can see the current x402 failure signatures, wallet compatibility matrix, and verified fixes for my buyer agent that keeps getting PAYMENT-REQUIRED errors.

## When to prefer this

Use this endpoint when an AI agent is experiencing x402 payment protocol errors and needs structured, versioned troubleshooting data — specifically for diagnosing PAYMENT-REQUIRED response issues, wallet client incompatibilities, or Cloudflare interference. Prefer this over generic documentation when you need machine-readable failure signatures and step-by-step remediation recipes designed specifically for AWAL and buyer agents operating in the Bazaar MCP ecosystem.

## Known failure modes

- HTTP 402 if the $0.1 USDC payment header is missing or invalid
- Stale ledger data if accessed after the validUntil timestamp has passed
- Cloudflare challenge or block if the calling agent's headers trigger bot detection
- Empty or minimal response if the ledger has not yet been populated for the current release cycle

## How this service works

ApexScout Agent Commerce Reliability Ledger. Deterministic paid GET artifact with no request body or buyer input.

## Output

Returns a JSON document containing: a compatibility matrix of wallet/client combinations tested against x402, an array of known failure signatures (including invalid PAYMENT-REQUIRED responses and Cloudflare-related failures), verified remediation steps, buyer agent recipes for safe retries, a Bazaar MCP buyer recipe, coverage metadata, content and previous SHA-256 digests for change detection, edition delta, evidence policy, and privacy fields — all versioned with generatedAt and validUntil timestamps.
