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
2. Backend
cd backend
python -m venv venv
source venv/bin/activate
pip install -r requirements.txt
cp .env.example .env
alembic upgrade head
uvicorn app.main:app --reload
3. Frontend
cd web
npm install
npm run dev

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:
| Category | Sources |
|---|
| Web search | Serper.dev, Brave Search, SerpAPI (fallback chain) |
| Fact-check | Google Fact-Check API |
| Government | GOV.UK, Hansard, GovInfo, Companies House, ONS |
| Legal | UK Legislation (legislation.gov.uk) |
| Economic | FRED, Marketaux, World Bank |
| Academic | Semantic Scholar, OpenAlex, PubMed |
| Climate | NOAA, WeatherAPI, Open-Meteo, GBIF |
| Archives | Wikipedia (+ reference mining), Library of Congress, Internet Archive |
| Health | WHO |
| Sports | Transfermarkt, Football-Data.org |
| Video | YouTube Data API |
Six Evidence Views
| View | Question it answers |
|---|
| Cartographer | What's the shape of this conversation? |
| Librarian | Is this the full set, clearly labelled? |
| Interpreter | Does this evidence answer this sub-question? |
| Projectionist | What's been said on camera? |
| Chronologist | When did the evidence appear? |
| Seeker | What don't we know yet? |
API & Agent Access
Tru8 exposes a developer API and MCP server for AI agents.
Agent Commerce Gateway
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%"}'
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"}'
| Tier | Cost | Time | What you get |
|---|
| Lookup | ~£0.02 | instant | Cached prior analysis |
| Consensus | ~£0.03 | instant | Cross-user aggregate landscape (k>=3 checks) |
| Quick | ~£0.07 | ~15s | Web search + heuristic classification |
| Full | ~£0.15 | ~60-90s | web + specialist APIs, LLM classification, element decomposition |
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

Infrastructure
| Service | Port | Purpose |
|---|
| PostgreSQL 16 | 5433 | Primary database (SQLModel) |
| Redis 7 | 6379 | Cache + rate limiting |
| Qdrant | 6333 | Vector similarity search |
| MinIO (optional) | 9000 | Local S3 for file uploads |
Auth: Clerk (JWT + JWKS) for dashboard, API keys for developer access.
Payments: Stripe (4 subscription tiers) + Agent per-use payments.
