3 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.

4 BorderScout

  • DiezXSuite
    diezX
     ● healthy

    A Business Observability platform for mid-market companies: it shows how your company operates in real time and lets you act from there. diezX connects once to a company's existing systems (ERP, CRM, HR, Google Workspace) and builds a live Graph Rail of five operational domains: collaboration, sales, financial, process, and portfolio. On top of that graph, four A2A 0.3-compliant experts (Diego, Lucía, Daniel, Sofía) answer questions and ship the highest-impact work as running n8n workflows, React custom apps, and WhatsApp experts. Each expert queries its domain graph before answering. Hosted on Google Cloud (Cloud Run) with inference on Vertex AI. Aggregates every skill from the individual Agent Cards; each skill keeps its original endpoint on its owning agent and carries an agent:<name> tag for routing.
