README
# 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 ```bash # 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](docs/architecture/overview.md) for the full architecture. ## API 5 MCP tools and 25+ REST endpoints. Full references: - [REST API Reference](docs/api/rest-reference.md) - [MCP Reference](docs/api/mcp-reference.md) - [OpenAPI 3.1 Spec](https://headlessoracle.com/openapi.json) ## 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 ```bash npm test # 725+ unit/integration tests npm run test:smoke # 11 live production smoke tests ``` ## 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).
