Bridge Status Tracker
x402
Bridge Status Tracker is a paid API for AI agents from 402.com.tr, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).
Tracks the completion status of a cross-chain bridge transfer using its source transaction hash via the LiFi status API.

How this service works
The other half of bridge-route. A bridge takes minutes with funds in flight, and from the source chain alone an agent cannot tell if it completed. Tracks a transfer by its source tx hash via the LiFi status API: completed (with the receiving tx), pending (poll again), failed (with the reason), or not-found (not a bridge tx, or too early to index). Pass from/to/bridge for a faster lookup. not-found reads as 'not indexed yet', never 'failed'. Not financial advice.
Output
Returns one of four statuses: 'completed' (with the destination chain receiving tx hash), 'pending' (transfer still in flight, poll again later), 'failed' (with a reason string explaining what went wrong), or 'not-found' (transfer not yet indexed — not a failure, just too early).
Example use cases
Confirming funds arrived after bridging
“I bridged some ETH from Arbitrum to Base about 5 minutes ago — tx hash is 0xd4e7f2...abc. Can you check if the transfer completed and if so give me the receiving transaction hash?”
Diagnosing a stuck or failed bridge
“My bridge transfer has been pending for over 20 minutes and I'm worried it failed. The source tx hash is 0x8f3a12...99e, it was from Polygon to Optimism. Can you tell me if it failed and why?”
Automated bridge completion polling in a workflow
“I just submitted a bridge transaction with hash 0x5c91ab...44f going from Base to Ethereum — keep checking its status until it either completes or fails and let me know the outcome.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/bridge-status?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent has already initiated a cross-chain bridge transfer and needs to confirm its outcome. It is the natural complement to a bridge-route/initiate endpoint. Prefer this over general blockchain explorers when you need a normalized status (completed/pending/failed) rather than raw transaction data, and when you need the destination-chain receiving tx hash. Pass optional from/to/bridge parameters for faster lookups.
Side effects
- txHash not yet indexed returns 'not-found' — should be retried after a short delay, not treated as failure
- Invalid or non-bridge txHash returns 'not-found' permanently
- Missing required txHash parameter causes a bad request error
- Network or LiFi API downtime may cause upstream errors
