## 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 public-spending-anomaly-review-09e8c7ae -d '<json body>'
```

Example prompt: Can you review these 60 public spending records in USD and flag any duplicate IDs, budget overruns, or payee concentration above 2500 basis points? Let me know which rows to look at more closely.

## When to prefer this

Use this endpoint when you need a lightweight, structured anomaly-screening pass over a batch of up to 80 public or synthetic spending records and want specific, enumerated flag types: duplicate IDs, budget overruns, budget inconsistencies, and payee concentration. It is well-suited for pre-audit triage, research dataset validation, and oversight reporting workflows where you want machine-readable review leads rather than a full forensic audit. It is not a legal or fraud determination tool.

## Known failure modes

- More than 80 records submitted — request rejected with validation error
- Records array is empty — minimum 1 record required
- Invalid currency value (only USD supported)
- Invalid dataClass value (must be 'public' or 'synthetic')
- concentrationThresholdBps outside 1–10000 range — rejected
- Malformed or oversized sourceSetDigest string
- Missing required fields in individual spending records — partial flags or parse errors
- Payment not confirmed — x402 payment required before processing

## How this service works

Review up to 80 public or synthetic spending records for duplicate IDs, inconsistent budgets, budget overruns and declared payee concentration. Duplicate-ID rows are excluded from totals. Flags are review leads, not fraud or legality findings. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

## Output

Returns a structured review of the submitted spending records including: rows flagged for duplicate IDs (excluded from totals), records with inconsistent or contradictory budget figures, transactions exceeding declared budgets, payee concentration analysis against the supplied threshold in basis points, and an overall anomaly summary. Results are retained for 24 hours and receipt metadata for 90 days.
