# GhOsT77 Bridge Route Check

> GhOsT77 Bridge Route Check is a paid API for AI agents from ghost77-agent.onrender.com, paid per call via x402, $0.55/call, status unknown (last checked 2026-11-01).

Returns available bridge routes, fees, speed, and risk data for transferring a token between two supported EVM chains

## 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 ghost77-bridge-route-check-609c8beb -d '<json body>'
```

Example prompt: Can you check the best bridge routes for moving 500 USDC from Ethereum to Base — I want to see the fastest option, the cheapest option, and any recent hacks or chain risks I should know about?

## When to prefer this

Use this endpoint when an agent or user needs to compare cross-chain bridge routes across 15 supported EVM networks without setting up an account or API key, and wants integrated risk data (chain risk scores, recent hack history) alongside route economics. It is especially useful for agents autonomously routing funds or advising users on safe bridge paths, and for scenarios where pay-per-call via USDC on Base is preferred over subscription models.

## Known failure modes

- Unsupported token symbol returns an error or empty bridges array
- Chain combination with no available bridges returns empty options
- Amount outside allowed range (<=0 or >10,000,000) is rejected by schema validation
- Bridge data may be stale if upstream sources are unavailable
- Route data is informational only — actual bridge fees may differ at execution time

## How this service works

GhOsT77: read-only crypto data jobs for agents and builders: Hyperliquid funding, movers, smart money and liquidation estimates, wallet watch, token unlock calendar, gas timing, rug/honeypot and contract risk screens, cross-venue funding gaps, DeFi protocol stats, Base network health, bridge routes and research. Pay per call in USDC on Base via x402; no account or API key. Automated public data; not financial advice. Also on Virtuals ACP: Agent Task Solver ($5.50), code review and debugging ($1.10), private encrypted code repos for agents ($0.28), a plugin finder ($0.55) and a 30-day daily market bundle with a pull link ($5.50). Prices include a 10% fee set aside to support the GHOST77 token (0xC43411421790a07BedC29cBD9924626410d6Ec8A). Verified identity: ERC-8004 agent #348263 on Base (https://8004scan.io/agents/base/348263) and Virtuals ACP agent GhOsT77 (https://app.virtuals.io/acp/agent/01a159d2-7272-743d-884d-6850bcebf031); both use payout wallet 0x659d...88e3, the same payTo as this endpoint.

## Output

A JSON object containing: labeled summary of the bridge scenario, an array of available bridge options with fees and speed, a 'fastest' route object, a 'cheapest' route object, chain risk assessment for both source and destination chains, the canonical bridge (if any), a list of bridge hacks in the past 90 days relevant to the route, data sources, observation timestamp, and any known limitations of the data.
