  "markdown": "# SibFly — measured ground subsidence API (mm/year) for any US address\n\n**Is the ground under an address sinking?** SibFly returns **measured** vertical ground motion — subsidence and uplift, in **millimeters per year and inches per year** — for any US address, from **NASA OPERA Sentinel-1 InSAR** satellite radar. Measured, not modeled.\n\n- **Live API:** https://sibfly.com\n- **Docs (human + agent):** https://sibfly.com/docs\n- **Agent docs:** https://sibfly.com/llms.txt · **OpenAPI:** https://sibfly.com/openapi.json · **Machine schema:** https://sibfly.com/api/v1/schema\n- **MCP server:** `https://sibfly.com/mcp` (Streamable HTTP)\n\n## Quickstart\n```bash\n# 1) an AI agent can register itself — no human, no captcha\ncurl -X POST https://sibfly.com/api/v1/autonomous/register \\\n  -H \"Content-Type: application/json\" -d '{\"email\":\"YOUR_EMAIL\"}'\n\n# 2) measure the ground under an address\ncurl \"https://sibfly.com/api/v1/motion?address=1100+Congress+Ave+Austin+TX\" \\\n  -H \"Authorization: Bearer sf_live_...\"\n```\nReturns `velocity_vertical_mm_yr` / `_in_yr`, an uncertainty range, `assessment_code`, confidence, provenance, and cost. **Flat $0.40 per covered report; misses are free; free coverage/cost preflight via `?dry_run=1`.**\n\n## What it is\n- Data: **NASA OPERA DISP-S1** (Copernicus Sentinel-1 C-band InSAR), 30 m grid, 2016–present.\n- Vertical **mm/year of ground movement** (not elevation), measured, per exact 30 m cell, with uncertainty.\n- Coverage: US (expanding). Not real-time (source refreshes ~every 12 days); a screening estimate, not survey-grade.\n\n## For AI agents\nSelf-registration, free coverage/cost preflight, idempotency keys, per-key spend caps, scoped browser-safe keys, batch, webhooks, x402 (USDC on Base), test-mode keys, and a hosted **MCP server** with 9 tools: `check_ground_motion`, `check_portfolio`, `get_coverage`, `get_motion_history`, `get_account`, `get_usage`, `ask_inspector`, `register_agent`, `buy_credits`. The full, authoritative contract lives at **https://sibfly.com/llms.txt** and **https://sibfly.com/openapi.json** — always current.\n\n## Connect from an MCP client (Cline, Claude, Cursor, any Streamable-HTTP client)\n\nSibFly is a **hosted (remote)** MCP server — nothing to install or run locally.\n\n1. Get an API key (one call, free credits included, no captcha):\n   ```bash\n   curl -X POST https://sibfly.com/api/v1/autonomous/register \\\n     -H \"Content-Type: application/json\" -d '{\"email\":\"you@example.com\"}'\n   ```\n   Save the returned `api_key` (shown once). Or skip this step: connect without a key and call the `register_agent` tool from inside MCP.\n2. Add the server to your MCP client config (Cline: MCP Servers → Remote Servers, or `cline_mcp_settings.json`):\n   ```json\n   {\n     \"mcpServers\": {\n       \"sibfly\": {\n         \"type\": \"streamableHttp\",\n         \"url\": \"https://sibfly.com/mcp\",\n         \"headers\": { \"Authorization\": \"Bearer sf_live_YOUR_KEY\" }\n       }\n     }\n   }\n   ```\n   OAuth 2.1 (Dynamic Client Registration + PKCE) is also supported for clients that prefer a \"Connect\" flow — discovery at `/.well-known/oauth-authorization-server`.\n3. Try it: call `get_coverage` (free) on any US address, then `check_ground_motion` ($0.40, misses free). `dry_run: true` previews coverage, cost, and expected answer quality without billing. Out of credits? The `buy_credits` tool returns a payment link (card or crypto).\n\nSandbox: register with `{\"mode\":\"test\"}` for an `sf_test_` key — $100 fake credits, synthetic data, rehearse the whole flow for $0.\n\n## Use cases\nReal-estate due diligence · \"is my house sinking?\" for home buyers · insurance & mortgage underwriting screening · infrastructure and portfolio subsidence monitoring · geotechnical pre-screening.\n\n---\n_A product of SIB Scientific. Screening estimate from satellite radar (NASA OPERA / Sentinel-1 InSAR) — not an engineering, survey, or hazard determination._\n",
