Who it’s for

Sellers and researchers following changes in the public x402 catalog.

Price

Free.

Paid calls use x402 with USDC on Base. Read the quote before authorizing payment; examples below do not pay automatically.

Know the limits

A partial nonrandom sample is not market prevalence or ecosystem uptime. Removal needs an explicit paired active:true to active:false transition. Absence, a failed probe or unknown status is not removal; no cause is inferred.

A 30-second integration

Examples use placeholders. Plain requests to paid tools return a payment challenge, not a paid result. Free Lint can perform an unpaid public probe. Inspect the response status and evidence scope before using any result.

curl

curl -sS https://api.spendpreflight.com/v1/bazaar-delistings

MCP

Connect to https://api.spendpreflight.com/mcp. This product has no dedicated MCP operation. Discover current service capabilities with get_service_info, then use the documented HTTP route:

{
  "name": "get_service_info",
  "arguments": {}
}

SDK / JavaScript

Use standard fetch alongside the SpendPreflight SDK; the example does not invent a dedicated exported method.

// Node.js SDK integration: use your explicitly budgeted fetch.
// Plain fetch below never signs or pays. There is no dedicated
// spendpreflight SDK helper for this operation.
const response = await fetch('https://api.spendpreflight.com/v1/bazaar-delistings', { method: 'GET' });
console.log(response.status, await response.text());

Frequently asked questions

Does the tracker publish seller names?

No. It publishes derived aggregate observations, not seller identities, descriptions or private Lint submissions.

Can it tell me why Coinbase removed an endpoint?

No. It does not infer causes or claim access to private Coinbase policy rules.
