Research that pays its own way.

Give your agent one endpoint for a cited, multi-step public-source report. No account, API key, or subscription, just an MPP payment when the work is needed.

Public contract

Small surface. Useful answer.

The gateway stays deliberately narrow: one discoverable paid operation and a consistent JSON result that an agent can reason over.

Public VIN research

This machine-payment tier does not sell phone, email, private-address, relatives, dating, reverse-image, or precise-location lookups.

Response contract

Predictable JSON, sources included

Every completed request returns the report, cited source URLs, related questions, and a protocol-specific payment record.

JSON response

{
  "object": "mpp_research_result",
  "status": "completed",
  "report": "# Research report\n…",
  "sources": [{ "title": "…", "url": "https://…" }],
  "related_questions": ["…"],
  "payment": {
    "protocol": "mpp",
    "amount_usd": "0.90"
  }
}

For people and agents

Machines use the endpoint. Humans can still use the app.
