Research Scout Provider

Independent English/Spanish TypeScript provider that turns caller-supplied source metadata and excerpts into deterministic, traceable research fixtures. It exposes an HTTP API and an MCP-shaped stdio tool.

Proveedor TypeScript independiente en inglés/español que convierte metadatos y extractos proporcionados por el cliente en resultados de investigación deterministas y trazables. Expone una API HTTP y una herramienta MCP por stdio.

This service does not fetch source URLs or perform live fact-checking. It never contacts Stellar Bazaar. The public deployment is a standalone demonstration endpoint.

Live deployment: https://research-scout-provider.vercel.app

Public API

After deployment, the following routes are available:

Example request:

curl -X POST "$PROVIDER_URL/v1/research" \
  -H "content-type: application/json" \
  -d '{
    "query": "What is Stellar used for?",
    "locale": "en",
    "maxSources": 5,
    "sources": [{
      "title": "Example source",
      "url": "https://example.com/article",
      "excerpt": "Caller-provided evidence.",
      "publisher": "Example",
      "publishedAt": "2026-01-01T00:00:00Z"
    }]
  }'

The response contains summary, individually cited findings, normalized citations, explicit limitations, and mode: "local_fixture". Select Spanish with "locale": "es".

La respuesta incluye summary, findings con citas individuales, citations normalizadas, limitations explícitas y mode: "local_fixture". Usa "locale": "es" para español.

Input limits

• Query: 2–500 characters.

• Sources: 1–25 entries; only HTTP(S) URLs are accepted.

• Source title: up to 300 characters; excerpt: up to 2,000 characters.

• maxSources: 1–10, default 5.

• Local Node server request body: maximum 64 KiB.

• No credentials, wallet data, payment data, or secrets should be submitted.

Local development

Requires Node.js 20 or newer.

npm ci
npm run check
npm start

The local HTTP server listens on http://127.0.0.1:8787. To run MCP over stdio after building:

npm run build
npm run start:mcp

The MCP tool is named research_with_sources. Its input and output contract matches the HTTP endpoint.

Deploy to Vercel

This repository includes vercel.json and three serverless entry points under api/. Deploy it as a separate Vercel project:

npx vercel
npx vercel --prod

No environment variables are required. Vercel rewrites /, /health, and /v1/research to their corresponding serverless functions.

Safety and data policy

• No outbound network requests or browser automation.

• No persistence, authentication, payments, wallets, or credential handling.

• Stable source IDs are derived from source URLs with SHA-256 when omitted.

• Output synthesizes only caller-supplied text and is not independent verification.

• No integration with or publication to Stellar Bazaar.
