# ChainAnalyzer x402 Connectivity Ping

> ChainAnalyzer x402 Connectivity Ping is a paid API for AI agents from chain-analyzer.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Validates the full x402 payment settlement path (signature → CDP facilitator → on-chain transferWithAuthorization) for $0.01 USDC to confirm wallet, network, and facilitator wiring before making higher-value AML API calls.

## 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 chainanalyzer-x402-connectivity-ping-f2b2b40b
```

Example prompt: Run a cheap x402 connectivity check against ChainAnalyzer for $0.01 USDC to confirm my wallet, CDP facilitator, and on-chain transferWithAuthorization are all wired up correctly before I start making real AML screening calls.

## When to prefer this

Use this endpoint as a pre-flight check before invoking any higher-value ChainAnalyzer AML endpoints (sanctions screening, risk scoring, mixer detection). At $0.01 it is the cheapest way to confirm that the full x402 payment infrastructure — wallet, CDP facilitator, and on-chain settlement — is correctly configured and operational, avoiding wasted spend on failed expensive calls.

## Known failure modes

- Invalid or malformed x402 payment signature — returns 402 with rejection details
- CDP facilitator unreachable or misconfigured — network error or timeout
- on-chain transferWithAuthorization fails due to insufficient USDC balance
- wrong network/chain specified — settlement path mismatch
- wallet not authorized for transferWithAuthorization — on-chain rejection

## How this service works

Cheap connectivity-check endpoint. Verifies the full x402 settlement path (signature -> CDP facilitator -> on-chain transferWithAuthorization) for $0.01 so AI agents can validate wallet + network + facilitator wiring before committing to higher-value AML calls.

## Output

Returns a confirmation that the full x402 settlement path completed successfully — including signature verification, CDP facilitator routing, and on-chain transferWithAuthorization — giving the agent confidence that wallet and network configuration is correct for higher-value AML calls.
