  ScalpStream operates a family of machine-payable data APIs built for autonomous agents:
  RecallScout (active US FDA, NHTSA and CPSC recalls with severity normalised across the three
  regulators), AirScout (global air quality with an EPA-based outdoor-exertion verdict and the
  cleanest window ahead), BorderScout (all 85 US ports of entry ranked by drive-plus-wait
  time per lane), FuelScout (cheapest fuel - station-level for Spain, France and Italy,
  official regional averages for the US) and ScalpStream Research (impersonal ranked options,
  dividend, crypto and yield feeds). Every service is a plain HTTPS GET priced at a flat $0.01
  per request and settled per request over x402 (HTTP 402) in USDC on Base, Arbitrum or
  Polygon or XRP/RLUSD on the XRP Ledger - no accounts, no API keys, no subscriptions - with a
  free preview on every host, an A2A agent card and JSON-RPC endpoint per service, and a
  first-party local MCP server (scalpmcp) that buys from all of them with the user's own wallet.

    Machine-payable US recall lookups over x402. Given a product, brand, ingredient or vehicle
    (make/model/year), returns active recalls across FDA food/drug/device enforcement, NHTSA
    vehicle safety campaigns and CPSC consumer recalls in one query, with severity normalised
    onto one scale and the basis for each rating stated, plus hazard, remedy and the lot codes /
    UPCs needed to tell whether a specific unit is affected. $0.01 per request; free preview.

    given length. Modelled data (Copernicus CAMS via Open-Meteo), not a street-level sensor.

    SENTRI/NEXUS, Ready, FAST) for passenger, commercial or pedestrian traffic, because the
    nearest crossing is often not the fastest. $0.01 per request; free preview.

    Machine-payable, impersonal research feeds over x402: ranked 0-30 DTE options candidates
    (/picks), dividend and tax-free municipal income (/dividends), crypto scalp candidates
    (/crypto) and risk-adjusted crypto yields (/yields). Built to be polled - free previews carry
    a board fingerprint served as a weak HTTP ETag so an agent can learn the board has changed
    with a 304 before paying, and /schema publishes JSON Schema 2020-12 for every paid response.
    Paid requests require the header X-Compliance-Attestation. Not investment advice.
