5	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.	A	10.00	—	🔓 open
6	BorderScout Machine-payable US border-crossing queries over x402. Ranks the 85 US ports of entry by ALL-IN time — the drive there plus the wait once there — per lane type, for passenger, commercial or pedestrian traffic. The nearest crossing is often not the fastest. Live CBP data.	A	10.00	—	🔓 open
