How this service works
Describe a screen in plain English via `?q=` (e.g. 'oversold large caps up today on high volume'). An LLM parses it into a filter, screens the entire US market, optionally confirms oversold/overbought with RSI, and returns a ranked shortlist with a one-line rationale per name. No need to know the filter schema or run the enrichment loop yourself. From x402stock
Output
A list of securities (stocks, ETFs) that match the specified screening properties, including tickers and relevant attribute values for each matched instrument, returned as structured JSON data paid per call via USDC.
Example use cases
Dividend income stock discovery
“Screen the US stock market for large-cap stocks with a dividend yield above 4% and a payout ratio under 70% — I want a list of tickers that fit those criteria.”
Momentum ETF search
“Find me ETFs that have had strong price momentum recently — screen for ones that are up significantly over the past three months and have solid trading volume.”
Value stock filter for portfolio research
“I'm looking for undervalued US stocks — screen for companies with a low P/E ratio under 15, positive earnings, and a market cap above $1 billion.”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/screener/smart?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to dynamically filter the US equity and ETF universe by one or more financial or market properties in a single call. Prefer this over static data endpoints when the user's goal is discovery or screening rather than looking up a specific known ticker. It is well-suited for investment research workflows where criteria are flexible or user-defined.
Side effects
- Invalid or unrecognized property names in filter criteria return an error
- No matching securities found returns an empty result set
- Malformed query parameters cause a 400 bad request
- Payment not provided or insufficient USDC triggers a 402 Payment Required response
- Rate limiting or network issues may cause timeouts
