# Mizan x402 Bazaar Inspector — Per-Operator Report Card

> Mizan x402 Bazaar Inspector — Per-Operator Report Card is a paid API for AI agents from mizan-bazar.higgsfield.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a detailed health and conformance report card for a specific x402 API operator, including liveness, latency, pricing accuracy, and paid-purchase outcomes with on-chain transaction references.

## Facts

- Endpoint: GET https://mizan-bazar.higgsfield.app/api/pagella/api.loyalspark.online
- Price: $0.01/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 mizan-x402-bazaar-inspector-per-operator-report-card-51edb4fc
```

Example prompt: Pull the Mizan report card for api.loyalspark.online and tell me if it's live, x402-conformant, and whether it actually delivers content after payment — include any on-chain transaction details.

## When to prefer this

Use this endpoint when you need to evaluate a specific x402 API operator before paying for its services, verify post-payment delivery behavior, or audit on-chain transactions for a known hostname. Prefer this over the full bazaar listing endpoint when you only need data on one specific operator and want lower latency and cost. Best suited for due-diligence workflows before an agent commits to repeated paid API calls.

## Known failure modes

- Unknown or unlisted hostname returns empty or 404-style response — only the 1,031 operators indexed by GET /api/pagella are supported
- Operator may have no survey data yet if recently added
- Stale data if operator has not been probed recently
- Payment of $0.01 USDC required per call — insufficient balance causes request to fail
- Network timeout if the Mizan service itself is temporarily unavailable

## How this service works

Mizan report card for api.loyalspark.online: liveness across surveys, latency, x402 conformance, door price vs catalog, paid-purchase outcome (delivered / refused / charged-not-delivered) with on-chain tx

## Output

A structured report card for the specified x402 operator hostname including: liveness status across surveys, measured latency, x402 protocol conformance grade, comparison of advertised catalog price vs actual door price, paid-purchase outcome breakdown (delivered / refused / charged-not-delivered), and on-chain transaction hashes for verification.
