How this service works
Pay-per-request data tools for AI agents.
Output
Returns a JSON object with ok status, a list of strategy candidates (possibly empty), counts of total observations split into train/validation/test sets, the number of evaluated candidates, and a disclaimer noting output is deterministic research only and not financial advice or an order signal.
Example use cases
Systematic strategy discovery for quant fund
“I'm building a quant fund and need to discover viable systematic trading strategy candidates — can you run a strategy search and show me which candidates came out of the evaluation along with the train/test observation counts?”
Algorithmic strategy research for a portfolio
“I want to screen for algorithmic trading strategies that could complement my existing portfolio — search for strategy candidates and tell me how many were evaluated and which ones look promising.”
Backtesting candidate identification
“Before I commit to backtesting everything manually, can you search for quantitative strategy candidates to narrow down the list? Show me how many observations were used in training versus testing and which candidates survived evaluation.”
Technical details
Endpoint
POSThttps://x402.feld-feder.at/v1/quant/strategy-searchWhen to prefer
Choose this endpoint when you need a pay-per-request, agent-native quantitative strategy search that returns structured research output with clear train/validation/test splits. Prefer it over building your own backtesting pipeline when you want fast, deterministic strategy candidate screening without committing to a full research infrastructure. It is particularly useful for AI agents that operate in a micropayment context via x402 and need lightweight, on-demand strategy discovery.
Side effects
- Empty candidates list if no strategies match the criteria
- Payment failure or x402 protocol rejection if USDC payment is not properly attached
- Invalid or malformed request body returning an error
- Timeout if the strategy evaluation computation exceeds limits
- Server-side errors from the feld-feder.at host returning non-200 responses
