# x402-defi-intel Bridge Quote

> x402-defi-intel Bridge Quote is a paid API for AI agents from cryptodefidataintel-production.up.railway.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-16).

Returns the best cross-chain bridge route with fees, gas cost, and estimated execution time for moving tokens between blockchains.

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 x402-defi-intel-bridge-quote-a7b2709e
```

Example prompt: What's the best route and estimated cost to bridge 1000 USDC from Ethereum to Arbitrum — show me the gas cost, fees, and how long it will take?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically determine the optimal cross-chain bridge route before executing a transfer — especially when cost and speed tradeoffs matter. Prefer this over generic DeFi price feeds when the user specifically wants to move tokens between different blockchains and needs actionable fee and gas estimates. Best for agents building multi-step DeFi workflows that include bridging steps.

## Known failure modes

- No route found between specified chains or token pair — signal may return 'no_route'
- Invalid chain names or token addresses return a 400-level error
- Unsupported token pair on requested chains returns empty or low-confidence result
- fromAmount too small to cover bridge fees may return an error or zero destination amount
- Service unavailable on Railway deployment returns 5xx error

## How this service works

Crypto-agent toolkit: cross-chain DeFi intelligence + execution helpers + retrieval for agents. 16 endpoints: funding, open interest, long/short, token-safety, yield, prices, gas, tx-simulate, approval-check, bridge-quote, governance-search, lending, liquidations, protocol-search, swap-quote, token-resolve. Pay-per-call via x402.

## Output

Returns the recommended bridge protocol (e.g. Across), destination token amount after fees, fee cost in USD, gas cost in USD, estimated execution time in seconds, a human-readable route insight, the data source, and a confidence score between 0 and 1.
