# SignalHarness Wallet Duplicate Records Detector

> SignalHarness Wallet Duplicate Records Detector is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-16).

Analyzes caller-supplied wallet data to identify duplicate records and return structured warnings about detected anomalies.

## 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 signalharness-wallet-duplicate-records-detector-2f340e88 -d '<json body>'
```

Example prompt: Check this wallet transaction data for any duplicate records and tell me what anomalies or repeated entries you find: [paste wallet data here].

## When to prefer this

Choose this endpoint when you need to programmatically detect duplicate records within wallet or blockchain transaction data supplied by the caller, especially in agent-native pipelines where micropayment-per-call (x402) billing is acceptable. Prefer this over manual deduplication scripts when you need structured warnings, an audit receipt, and a cryptographic result hash for downstream verification.

## Known failure modes

- Input string too short (below 2 characters) or too long (above 65536 characters) returns a validation error
- Malformed or unparseable wallet data may return empty findings with generic warnings
- Payment failure via x402 protocol results in 402 response before execution
- Network or service downtime returns a non-'succeeded' status in the response
- Ambiguous or insufficiently structured wallet data may yield low-confidence or incomplete duplicate detection

## Output

Returns a JSON object containing a status field ('succeeded' or otherwise), a result object with a 'wallet_duplicate_records' field holding findings, a list of warnings about detected issues, and an evidence_scope indicator. Also includes a full receipt with payment ID, execution ID, request ID, network details, latency, and a SHA-256 hash of the result for auditability.
