# Relay Diagnostic Skill
Diagnoses and recovers stuck sponsored transactions by inspecting the sponsor relay's nonce state and optionally triggering automated recovery.
Use this for operator diagnostics only. Caller-facing x402 payment state should come from canonical payment-status polling by `paymentId`, not from relay health heuristics.
- **check-health** — Read-only, no wallet required. Returns relay version, sponsor nonce status, detected gaps, and stuck transactions.
- **recover** — Requires an unlocked wallet (to source the sponsor API key). Attempts RBF, gap-fill, or both.
## Usage
```
bun run relay-diagnostic/relay-diagnostic.ts <subcommand> [options]
```
## Subcommands
### check-health
Check the sponsor relay availability and nonce status. No wallet needed.
```
bun run relay-diagnostic/relay-diagnostic.ts check-health
```
Output:
```json
{
"healthy": true,
"network": "mainnet",
"version": "1.2.0",
"sponsorAddress": "SP1PMPPVCMVW96FSWFV30KJQ4MNBMZ8MRWR3JWQ7",
"nonceStatus": {
"lastExecuted": 4210,
"lastMempool": 4215,
"possibleNext": 4216,
"missingNonces": [],
"mempoolNonces": [4211, 4212, 4213, 4214, 4215],
"hasGaps": false,
"gapCount": 0,
"mempoolDesync": false,
"desyncGap": 5
},
"stuckTransactions": [],
"issues": [],
"formatted": "Relay Health Check (mainnet)\nStatus: HEALTHY\n..."
}
```
### recover
Attempt automated recovery of stuck transactions. Requires an unlocked wallet.
```
bun run relay-diagnostic/relay-diagnostic.ts recover [options]
```
Options:
- `--action <rbf|fill-gaps|both>` — Recovery mode (default: `both`)
- `--txids <txid,...>` — Comma-separated list of specific stuck txids for RBF (omit to bump all)
- `--nonces <n,...>` — Comma-separated list of specific missing nonces for gap-fill (omit to fill all)
Output:
```json
{
"action": "both",
"rbf": {
"supported": true,
"result": { "bumped": 2 }
},
"fillGaps": {
"supported": true,
"result": { "filled": 0 }
},
"summary": "Recovery request sent to relay. Run check-health to verify nonce state improved."
}
```
## Notes
- Always run `check-health` before `recover` — recovery without a prior health check may bump transactions unnecessarily.
- If the relay returns 404 or 501 for recovery endpoints, the tool reports `supported: false` with instructions to contact the AIBTC team.
- The sponsor address for mainnet is `SP1PMPPVCMVW96FSWFV30KJQ4MNBMZ8MRWR3JWQ7`.
- Wallet operations require an unlocked wallet (use `bun run wallet/wallet.ts unlock` first).
