ScalpStream Research
Machine-payable, impersonal research feeds over x402: ranked options candidates, dividend/tax-free income, crypto scalp candidates, and best interest-paying cryptos. Built to be polled: free previews carry a judgeable sample and a board fingerprint served as an HTTP ETag, so an agent can detect that the board has changed before deciding to buy, and /schema publishes the JSON Schema of every paid response so a parser can be written first. The full feed settles in XRP/RLUSD (XRPL) or USDC (Base/Arbitrum/Polygon). Not investment advice.
