How this service works
Programmable authority checks and tamper-evident receipts for autonomous agents, sold through sustainable x402 commerce.
Output
Returns a JSON object with a 'decision' field (e.g. 'manual_review'), a 'risk_score' integer (0–100), a 'findings' array of detected issues (e.g. [{"code":"multiple_testing_risk"}]), and a 'simulation_only' boolean indicating whether the report is based solely on simulated data.
Example use cases
Pre-deployment strategy audit
“I have a backtest report for my mean-reversion equity strategy — run it through the integrity checker and tell me the risk score and whether there are any multiple-testing or simulation-only flags I should worry about before I deploy it.”
Overfitting detection for quant researcher
“I've been running dozens of parameter combinations on this backtest and I'm worried about overfitting — can you submit this report and check what the integrity findings say, especially around multiple-testing risk?”
Compliance review for autonomous trading agent
“Our trading agent generated this backtest report last night — can you validate it for integrity issues, get the decision outcome, and flag anything that would require a manual review before it's approved for live trading?”
Technical details
Endpoint
POSThttps://capi2-agent-commerce.vandurmedries.workers.dev/v1/backtest-integrityWhen to prefer
Choose this endpoint when you need a programmatic, tamper-evident integrity check on a quantitative backtest report — especially when you want to detect multiple-testing bias, simulation-only artifacts, or other methodology risks before deploying an autonomous trading agent. It is suited for autonomous agent pipelines where a lightweight, pay-per-call (x402) validation gate is needed without setting up a full risk infrastructure.
Side effects
- Missing or malformed 'report' object returns a 4xx validation error
- Ambiguous or empty report body may yield inconclusive findings with no actionable decision
- Payment failure via x402 protocol results in 402 response and no analysis
- Upstream worker unavailability may return 503 or timeout
- Report with insufficient data fields may produce a low-confidence or default risk score
