Documentation Overview
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
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.
API
5 MCP tools and 25+ REST endpoints. Full references:
Exchanges
23 traditional markets (XNYS, XNAS, XLON, XJPX, XPAR, XHKG, XSES, XASX, XBOM, XNSE, XSHG, XSHE, XKRX, XJSE, XBSP, XSWX, XMIL, XIST, XSAU, XDFM, XNZE, XHEL, XSTO) plus 5 extended (XCBT, XNYM, XCBO, XCOI, XBIN). DST handled automatically via IANA timezone names. Lunch breaks, half-days, and holidays for 2026-2027.
Testing
Security
Ed25519 signatures on every response. 60-second receipt TTL. Fail-closed architecture (UNKNOWN = CLOSED). Security headers on all responses (HSTS, CSP, X-Content-Type-Options, X-Frame-Options).
