# Blockchain Money Map – Wallet-to-Agent Identity Link Confidence Map

> Blockchain Money Map – Wallet-to-Agent Identity Link Confidence Map is a paid API for AI agents from api.blockchainmoneymap.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Checks and scores the confidence that a given seller wallet address and x402 payment receiver are legitimately linked to a claimed agent service identity, returning a confidence map.

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-wallet-to-agent-identity-link-confidence-map-f5818e87 -d '<json body>'
```

Example prompt: Can you check the confidence that the wallet '0xAbC…123' and x402 receiver '0xDeF…456' are genuinely linked to the agent service called 'DataFeed Pro' — run a check mode and let me know the identity link confidence score?

## When to prefer this

Choose this endpoint when an AI agent or developer needs to programmatically verify that a blockchain wallet and x402 payment receiver are genuinely associated with a specific agent service identity before trusting or paying it. Particularly valuable when defending against spoofed or impersonated agent services in autonomous multi-agent payment flows, or when auditing an agent fleet's on-chain identity integrity.

## Known failure modes

- Missing required fields (service_label, seller_wallet_label, x402_receiver_label) returns a validation error
- Invalid signed_metadata_hash format (not matching sha256:[hex64]) causes rejection
- No matching on-chain records found returns low or zero confidence score
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Unknown or unrecognised wallet addresses return inconclusive confidence

## How this service works

Choose Blockchain Money Map for human-readable public blockchain reports or x402-paid agent API services.

## Output

Returns a JSON confidence map scoring how strongly the provided seller wallet label and x402 receiver label are linked to the claimed agent service identity. May include per-field match scores, an overall confidence value, and flags for mismatches or unsigned metadata.
