NIGHTCRAWLER

Autonomous Open-Source Intelligence agent that corroborates open-web signals and sells high-conviction alpha to other agents over x402.

Inspiration

Public data is everywhere — flight logs, government filings, options tape — but turning it into actionable intelligence still takes teams of analysts and hours of manual work. We asked: what if an autonomous agent could connect those dots in seconds, prove its reasoning with ground-truth citations, and sell the insight to other agents? That became NIGHTCRAWLER: "Data is public. Intelligence is proprietary."

What it does

NIGHTCRAWLER ingests open-web intelligence into ClickHouse, detects anomalies across independent data streams, and autonomously corroborates them before synthesizing a high-confidence signal. Findings stream live to a Conspiracy Board UI, pause at a Guild.ai human approval gate, publish citations to cited.md via Composio, and sell the actual trade signal behind an x402 crypto paywall that buyer agents unlock with USDC on Base Sepolia.

How we built it

We used a contract-first, 3-person parallel build in a pnpm/Turborepo monorepo. Teammate A owned data ingest and ClickHouse; Teammate B built the OpenAI agent with Langfuse tracing, Guild approval gate, and Composio publishing; Teammate C shipped the Next.js Conspiracy Board UI, SSE streaming, and x402 payment rail. Shared schemas in packages/contracts let all three tracks build in parallel against frozen fixtures before live integration.

Challenges we ran into

The hardest part was proving the agent wasn't just guessing from a single coincidence — we solved that with a mandatory multi-vector corroboration loop and Langfuse traces. Parallel development under hackathon time pressure required contract-first design so the UI could ship before the live agent was wired. Balancing agent speed with human governance, and getting x402 payments working reliably on testnet, also took real iteration.

Accomplishments that we're proud of

We built a complete end-to-end agent economy in one day: ingest, corroborate, approve, publish, and monetize. We integrated seven sponsor technologies into one coherent demo, streamed a live Conspiracy Board as the agent reasoned, published real citations to cited.md, and demonstrated a buyer bot autonomously paying to unlock alpha.

What we learned

Frozen contracts and mock fixtures matter as much as the real implementations — they let three people ship without blocking each other. The product isn't the LLM's guess; it's the agent seeking independent proof and showing its work. Public citations establish trust, and x402 establishes price — together they sketch a viable alpha marketplace.

What's next for NightCrawler

Live Airbyte connectors for real FAA, SEC, and options data. Generalized multi-scenario anomaly detection beyond the demo narrative. An on-chain alpha marketplace with reputation scores, richer Thesys C1 visualizations, and stronger compliance checks before any signal is published or sold.
