```

Example prompt: Can you run a backtest on a momentum trading strategy for crypto using ScriptMasterLabs and show me how it would have performed historically?

## When to prefer this

Use this endpoint when you need pay-per-call access to strategy backtesting without a subscription, and your agent can handle x402 micropayment flows on Base. Best suited for crypto and RWA strategy validation at very low cost ($0.001 USDC per call). Prefer alternatives with richer schemas if you need detailed parameter control or guaranteed response structure.

## Known failure modes

- Missing or malformed strategy properties parameter returns an empty or error response
- Payment not settled in USDC on Base causes 402 Payment Required rejection
- Unsupported strategy type returns empty example response
- Render.com cold-start latency may cause initial timeout
- Poorly documented input schema may cause silent failures with unexpected parameters

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output
