Headless Oracle

Ed25519-signed market-state attestations for 28 global exchanges.

What It Does

Autonomous trading agents need to know if an exchange is open before executing trades. Headless Oracle answers that question with a cryptographically signed receipt that any agent can verify independently — no trust in the operator required. UNKNOWN states are always treated as CLOSED (fail-closed).

Quick Start

# MCP (Claude Desktop, Cursor, any MCP client)
npx headless-oracle-mcp

# REST API — demo receipt (no auth required)
curl https://headlessoracle.com/v5/demo?mic=XNYS

# Instant sandbox key (200 calls, 7 days, no signup)
curl https://headlessoracle.com/v5/sandbox

Architecture

Single TypeScript Cloudflare Worker (~14,000 lines). Ed25519 signing via @noble/ed25519. Three KV namespaces (overrides, API keys, telemetry). Two Durable Objects (webhooks, SSE streams). Deployed to 300+ edge locations globally.

4-tier fail-closed: KV override check -> schedule engine -> UNKNOWN fallback -> unsigned critical failure.

See docs/architecture/overview.md for the full architecture.
