# x402 Chain Intel – Bridge Routes > x402 Chain Intel – Bridge Routes is a paid API for AI agents from x402-chain-intel.vercel.app, paid per call via x402, $0.07/call, status unknown (last checked 2026-10-12). Returns available cross-chain bridge routes for a given token transfer, enabling trading bots to find optimal bridging paths between blockchains. ## Facts - Endpoint: POST https://x402-chain-intel.vercel.app/api/bridge/routes?utm_source=zero.xyz - Price: $0.07/call - Payment: x402 - Status: unknown - Last checked: 2026-10-12 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/x402-chain-intel-bridge-routes-092c26db - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_IfNHe4XKolkJZTtRohx4Q 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-chain-intel-bridge-routes-092c26db -d '' ``` Example prompt: Look up available bridge routes to move 5000 USDC from Ethereum mainnet to Arbitrum — I need to compare fees and estimated settlement times before my bot executes the transfer. ## When to prefer this Use this endpoint when a trading bot or DeFi agent needs to programmatically discover and compare cross-chain bridge routes before executing a transfer. Prefer this over generic swap APIs when the primary need is bridging assets between Layer 1 and Layer 2 networks or between distinct chains, rather than swapping tokens on a single chain. ## Known failure modes - Unsupported chain pair returns empty routes array or 404 - Token not supported on one or both chains returns error - Amount below bridge minimum threshold returns validation error - Network congestion may cause stale or missing route estimates - Malformed chain ID or token address returns 400 bad request ## How this service works 27 paid endpoints for trading bots ## Output A list of available bridge routes for the requested cross-chain token transfer, including the bridge protocol name, estimated output amount after fees, protocol fee, estimated settlement time, and any relevant route metadata. The agent can use this to programmatically select the optimal bridge for execution. ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/x402-chain-intel-bridge-routes-092c26db/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from x402-chain-intel.vercel.app](https://www.zero.xyz/host/x402-chain-intel.vercel.app/llms.txt)
