# Blockchain Money Map x402 Payment Method Disclosure Normalizer

> Blockchain Money Map x402 Payment Method Disclosure Normalizer is a paid API for AI agents from api.blockchainmoneymap.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).

Normalizes and maps x402 payment method disclosure facts (payment handlers, supported tokens, networks) into a structured canonical form, optionally diffing against a reference set.

## Facts

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 blockchain-money-map-x402-payment-method-disclosure-normalizer-5c513d5d -d '<json body>'
```

Example prompt: Normalize my x402 payment method disclosure: payment handlers are ['stripe-crypto','coinbase-commerce'], supported networks are ['base','ethereum'], supported tokens are ['USDC','ETH'], and buyer disclosures say 'funds are non-refundable' — map these into a canonical disclosure structure.

## When to prefer this

Use this endpoint when you need to canonicalize, normalize, or diff x402 payment method disclosure facts — particularly when building or validating API payment disclosures for blockchain-based agent-to-agent or human-facing payment flows using the x402 protocol. Prefer this over manual structuring when you have raw disclosure arrays that need standardization or when comparing new payment configurations against a known-good reference.

## Known failure modes

- Missing required fields (payment_handlers, supported_networks, supported_tokens) returns validation error
- Array items exceeding maxItems:50 limit rejected
- Invalid mode value (must be 'normalize') causes error
- Malformed JSON input returns parse error
- Payment failure (insufficient USDC balance) returns 402
- Policy object with conflicting rules may yield unexpected normalization output

## How this service works

Maps payment rails, handlers, tokens, networks, wallet requirements, and buyer disclosures.

## Output

A JSON object containing the normalized and canonicalized payment method disclosure map, with structured arrays for payment handlers, supported tokens, networks, settlement networks, wallet requirements, buyer disclosures, and a resolved default method label. If reference_facts are provided, the response may include a diff or comparison highlighting changes.
