How this service works
OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana, Algorand and Polygon via x402.
Output
Returns a JSON object containing historical backtest performance metrics such as total return, annualized return, maximum drawdown, win rate, Sharpe ratio, and a log of simulated trades executed during the backtest period.
Example use cases
Validate crypto strategy before deploying capital
“Before I go live, can you backtest my momentum strategy on crypto markets and tell me what the annualized return and max drawdown would have been?”
Compare multiple strategy configurations
“Run a backtest with my mean-reversion strategy parameters and show me the trade-by-trade performance so I can see where it wins and loses.”
Evaluate strategy for DeFi agent automation
“I'm building an AI trading agent on Base — can you backtest a RSI-based strategy for me and give me the Sharpe ratio and win rate so I know if it's worth automating?”
Technical details
Endpoint
GEThttps://markets.losbeto.xyz/backtest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically evaluate a trading strategy's historical performance with micropayment-based access via x402 on Solana or Base. Preferred over manual backtesting tools when integrating into an AI agent workflow that requires automated strategy validation at low per-call cost ($0.06 USDC).
Side effects
- Missing or malformed 'properties' parameter returns an error or empty result
- Invalid strategy configuration causes computation failure
- Strategy parameters outside supported range may return 400 or empty JSON
- Payment of $0.06 USDC required; unpaid requests return HTTP 402
- Server-side timeout for computationally expensive backtests
