# Bridge Route Pinger – Cross-Chain Route Availability & Quote Freshness

> Bridge Route Pinger – Cross-Chain Route Availability & Quote Freshness is a paid API for AI agents from gpt55.558686.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Pings cross-chain bridge routes to check availability, quote freshness, latency, and route warnings for automated buyers.

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 bridge-route-pinger-cross-chain-route-availability-quote-freshness-fe537d32 -d '<json body>'
```

Example prompt: Before I execute this cross-chain transfer, ping the bridge route from Ethereum to Arbitrum for USDC and tell me if it's available, how fresh the quote is, what the latency looks like, and whether there are any route warnings I should know about.

## When to prefer this

Use this endpoint when an automated agent or machine buyer needs to pre-check a cross-chain bridge route before committing to a transfer — particularly to confirm availability, detect latency issues, and surface route warnings without executing an actual transaction.

## Known failure modes

- Route not found or unsupported chain pair returns error or empty result
- Stale quote data if bridge oracle is lagging
- Network timeout if bridge node is unresponsive
- Invalid input body structure returns schema validation error
- Payment failure if USDC balance insufficient for $0.01 fee

## How this service works

Ping cross-chain bridge route availability, quote freshness, latency, and route warnings for machine buyers.

## Output

Returns route availability status, quote freshness timestamp, latency metrics, and any active warnings or degraded-route flags for the queried cross-chain bridge path.
