Paid data product

Agent Commerce Reliability Ledger

A bodyless GET for agents that need machine-readable x402 payment-to-outcome evidence: buyer-client compatibility, retry controls, delivery and receipt checks, settlement boundaries, known failure signatures, and bounded remediation. Returns a versioned JSON ledger with digest and expiry; it never initiates payment or handles buyer identity.

The preview does not pay, open a wallet, create an account, or expose the full ledger.

Representative evidence

Compatibility

AWAL CLI 2.12.0

Canonical PAYMENT-REQUIRED parsing is verified without payment.

Failure RCL-001

header body version mismatch

The client can inspect the route but rejects the payment-required response as invalid.

What changed in this edition

Refreshed the public evidence window, marked older compatibility observations stale under the existing 30-day rule, and aligned Bazaar metadata with the bodyless payment-to-outcome buyer job. No new paid compatibility claim was added.

Buy through Bazaar MCP

1. Discover

search_resources

Search for agent commerce reliability data and select the ApexScout Ledger.

2. Purchase

proxy_tool_call

The buyer-side x402 MCP client applies its own wallet approval policy and returns the complete Ledger after settlement.

MPP-native buyer path

1

Discover ApexScout through MPPScan or the mpp.dev catalog after an owner-controlled listing is public; until then use the canonical ApexScout preview and docs.

2

Inspect GET /api/agent-commerce-reliability-ledger and confirm the fixed $0.10 charge.

3

Verify tempo/charge, Tempo eip155:4217, 100000 atomic USDC, recipient, issuedAt, and expiresAt from the live challenge.

4

Confirm the current Ledger edition and content digest on the free preview.

5

Ask for explicit buyer approval for one $0.10 call.

6

Pay once with the buyer's own MPP client. ApexScout never operates the buyer wallet.

7

Require Payment-Receipt, HTTP 200, and the complete Ledger delivery.

8

Stop after delivery or any mismatch, expiry, rejection, or incomplete response; never pay or retry automatically.

If the Commerce Intent expires before payment begins, fetch one fresh unpaid challenge without a payment credential, verify identical terms, and ask for fresh approval. The refresh is stateless and a settled intent can never refresh into another charge.
