# RetryBot Failed Transaction Retry Service

> RetryBot Failed Transaction Retry Service is a paid API for AI agents from agenthealthmonitor.xyz, paid per call via x402, $10/call, status unknown (last checked 2026-09-15).

Analyzes failed blockchain transactions for a given wallet address, classifies failure reasons, and returns optimized ready-to-sign replacement transactions with corrected gas parameters

## Facts

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 retrybot-failed-transaction-retry-service-e9bd239a
```

Example prompt: My wallet 0xd8da6bf26964af9d7eed9e03e53415d37aa96045 has a bunch of failed transactions — can you analyze them and give me optimized replacement transactions ready to sign so I can recover the value?

## When to prefer this

Use this endpoint when an AI agent or user needs to recover value from failed blockchain transactions without manually diagnosing each failure. Ideal when you have a wallet address with multiple failed transactions and want ready-to-sign corrected transactions rather than raw diagnostics. Prefer over manual gas estimation when the failure reason is unclear or when multiple transaction types are involved.

## Known failure modes

- Invalid or malformed wallet address returns 400 error
- Address with no failed transactions returns empty retry_transactions array
- Network congestion may cause stale gas estimates
- Transactions older than lookback window may not be analyzed
- Payment failure via x402 protocol returns 402 response
- Some failed transactions may be non-retryable and excluded from results

## How this service works

RetryBot: Non-custodial failed transaction retry service. Analyzes failed transactions, classifies failure reasons, and returns optimized ready-to-sign replacement transactions with corrected gas parameters. Agent signs and submits.

## Output

Returns a JSON report containing: analyzed wallet address and timestamp, count of retryable transactions, array of retry transactions each with failure reason classification (e.g. out_of_gas), original tx hash, fully constructed optimized replacement transaction (to, data, value, gas_limit, max_fee_per_gas, max_priority_fee_per_gas), confidence level, and estimated gas cost in USD. Also includes total failed transactions analyzed, potential USD value recoverable, and total estimated retry cost.
