Tru8 Evidence Research

Tru8 — AI-Powered Evidence Research Platform

Tru8 organises evidence so you can decide what matters. Submit a claim or URL, and Tru8 retrieves evidence from the open web and specialist APIs, classifies it by tier (primary / reporting / commentary) and type (data / official / news / analysis / opinion / academic), decomposes claims into elements, maps evidence to those elements, and presents the full landscape — structured, not summarised.

Mission: "We organise; you decide."

Quick Start

Prerequisites

• Docker & Docker Compose
• Python 3.11+
• Node.js 20+

1. Start Infrastructure

docker-compose up -d    # PostgreSQL 16, Redis 7, Qdrant

2. Backend

cd backend
python -m venv venv
source venv/bin/activate    # Windows: venv\Scripts\activate
pip install -r requirements.txt
cp .env.example .env        # Edit with your API keys
alembic upgrade head
uvicorn app.main:app --reload    # http://localhost:8000

3. Frontend

cd web
npm install
npm run dev    # http://localhost:3000

Pipeline

Two-phase pipeline with user claim selection gate (article mode):

Phase 1:  Ingest → Extract claims → Classify article → Rank claims
          [PAUSE — user selects claims]

Phase 2:  Fact-check lookup → Decompose into elements → Retrieve evidence →
          Score relevance → Classify tier/type → Map evidence to elements →
          Derive orientation → Complete

Post:     Coverage recovery (Stage 5.1), video recommendations, auto-archiving

Evidence flows through web search plus specialist source adapters:

Six Evidence Views

API & Agent Access

Tru8 exposes a developer API and MCP server for AI agents.

Agent Commerce Gateway

# Quick check (~15s, heuristic classification)
curl -X POST https://api.trueight.com/api/v1/agent/quick \
  -H "X-API-Key: $TRU8_API_KEY" \
  -d '{"claim": "UK inflation is 3.2%"}'

# Smart endpoint with tier fallback (lookup → consensus → quick → full)
curl -X POST https://api.trueight.com/api/v1/agent/check \
  -H "X-API-Key: $TRU8_API_KEY" \
  -d '{"claim": "UK inflation is 3.2%", "max_tier": "full"}'

Three payment rails: x402 (USDC/SIWE), Skyfire (JWT), prepaid credits.

MCP Server

{
  "mcpServers": {
    "tru8": {
      "command": "python",
      "args": ["-m", "tru8_mcp"],
      "env": { "TRU8_API_KEY": "tru8_sk_..." }
    }
  }
}

Tools: tru8_check (evidence research with tier fallback), tru8_get_result (with analytics), tru8_get_result_raw.

Manifest Verification

Every completed check receives an HMAC-SHA256 signed manifest. Verify the signed fields haven't changed since signing:

curl https://api.trueight.com/verify/{check_id}

Testing

cd backend
pytest tests/ -v                        # Full suite (990 tests)
pytest tests/unit/pipeline/ -v          # Pipeline unit tests
pytest tests/unit/agent/ -v             # Agent/commerce tests
pytest tests/integration/ -v            # Integration tests

Infrastructure

Auth: Clerk (JWT + JWKS) for dashboard, API keys for developer access. Payments: Stripe (4 subscription tiers) + Agent per-use payments.
