# Blockchain Money Map x402 Paid Route Boundary Mapper

> Blockchain Money Map x402 Paid Route Boundary Mapper is a paid API for AI agents from api.blockchainmoneymap.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Audits and validates x402-paid API route configurations by comparing declared facts against reference facts to detect discrepancies in tool definitions, schemas, and payment settings.

## 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 blockchain-money-map-x402-paid-route-boundary-mapper-1b10c44f -d '<json body>'
```

Example prompt: Audit my x402 paid route configuration for a tool called 'get-wallet-balance' on paid route '/api/x402/get-wallet-balance' — compare it against the reference facts to check whether the payment_required flag, alias, and input schema all match up correctly.

## When to prefer this

Choose this endpoint when you need to programmatically audit and validate the configuration of x402-paid API routes — particularly to detect drift between declared and reference tool definitions, verify payment flags are set correctly, or ensure schema consistency before deployment. Prefer this over manual inspection when automating CI/CD checks for x402-powered agent APIs.

## Known failure modes

- Missing required fields (tool_name, paid_route, input_schema, paid_operation_description) returns validation error
- Mode must be exactly 'audit' otherwise request is rejected
- Input schema exceeding 50 properties will be rejected
- Mismatched reference_facts structure causes comparison failure
- Network or payment processing failure returns 402 or 5xx error

## How this service works

Maps paid MCP tool surfaces against x402 routes and possible unpaid aliases.

## Output

A JSON audit result indicating whether the declared facts for the specified x402 paid route match the reference facts, with details on any discrepancies found in tool name, route paths, input schema, payment flags, alias settings, permission scope, or operation description.
