Ground Motion tools (9, 1 write)

write = sends, deletes, buys or posts
  • ask_inspectorFree

    FREE follow-up Q&A with the SibFly Inspector about a report you ALREADY BOUGHT (buy via check_ground_motion first). Ask what the numbers mean for foundations, staleness, seasonal swings, etc. It answers only from the report's numbers (never invents), and won't give buy/walk-away advice. Per-account message allowance applies.

  • buy_creditswrite actionFree

    Get a machine-usable payment link to top up credits (requires your Bearer API key). method 'stripe' returns a card checkout_url; 'crypto' returns a BTC invoice_url + txn_id. Open/relay the URL to complete payment; credits land automatically afterwards — confirm with get_account.

  • check_ground_motionFree

    Measured ground motion (sinking/uplift) for a US address or lat/lon, in mm/year AND in/year, from NASA OPERA Sentinel-1 InSAR. Costs $0.40 from your SibFly credits; out-of-coverage / too-stale / too-low-confidence / fuzzy-geocode return FREE. Use the gate params to avoid paying for data you'd reject. dry_run=true is a FREE coverage+cost preview.

  • check_portfolioFree

    Batch ground-motion for many US addresses in one call. Only covered addresses are billed ($0.40 each); misses and duplicate cells are free. If credits run out mid-batch the response status is 'insufficient_credits' and unbilled items are marked — top up (buy_credits) and retry them.

  • get_accountFree

    FREE: your SibFly credit balance, price per report, reports remaining, and top-up URL.

  • get_coverageFree

    FREE pre-flight: is a US address/point covered, how stale is the data (data_age_days), and what a report would cost. Accepts ONE address/lat+lon, OR addresses[] (up to 1000, needs your Bearer key) to size a whole job before spending. Call this before spending.

  • get_motion_historyFree

    Multi-year cumulative motion history for an address. Pass from_date and to_date (YYYY-MM-DD) to get the movement between two dates. Costs $0.40 (misses free). dry_run=true is a FREE preview (points + dates + cost, no data); max_age_days returns free instead of billing for stale data.

  • get_usageFree

    FREE: your recent billed calls (line-item ledger with request_id, endpoint, address, cost) so you can reconcile spend against reports.

  • register_agentFree

    FREE: create a new SibFly account and get an API key + free starter credits in ONE call — no human, no captcha, no card. Use this when you have no API key. SAVE the returned api_key and pass it as the Bearer token on later calls (MCP clients: set it as the Authorization header).

SibFly — measured ground subsidence API (mm/year) for any US address

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.

  • Live API: https://sibfly.com
  • Docs (human + agent): https://sibfly.com/docs
  • Agent docs: https://sibfly.com/llms.txt · OpenAPI: https://sibfly.com/openapi.json · Machine schema: https://sibfly.com/api/v1/schema
  • MCP server: https://sibfly.com/mcp (Streamable HTTP)

Quickstart

# 1) an AI agent can register itself — no human, no captcha
curl -X POST https://sibfly.com/api/v1/autonomous/register \
  -H "Content-Type: application/json" -d '{"email":"YOUR_EMAIL"}'

# 2) measure the ground under an address
curl "https://sibfly.com/api/v1/motion?address=1100+Congress+Ave+Austin+TX" \
  -H "Authorization: Bearer sf_live_..."

Returns velocityverticalmmyr / inyr, an uncertainty range, assessmentcode, confidence, provenance, and cost. Flat $0.40 per covered report; misses are free; free coverage/cost preflight via ?dryrun=1.**

What it is

  • Data: NASA OPERA DISP-S1 (Copernicus Sentinel-1 C-band InSAR), 30 m grid, 2016–present.
  • Vertical mm/year of ground movement (not elevation), measured, per exact 30 m cell, with uncertainty.
  • Coverage: US (expanding). Not real-time (source refreshes ~every 12 days); a screening estimate, not survey-grade.

For AI agents

Self-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: checkgroundmotion, checkportfolio, getcoverage, getmotionhistory, getaccount, getusage, askinspector, registeragent, buycredits. The full, authoritative contract lives at https://sibfly.com/llms.txt and https://sibfly.com/openapi.json** — always current.

Connect from an MCP client (Cline, Claude, Cursor, any Streamable-HTTP client)

SibFly is a hosted (remote) MCP server — nothing to install or run locally.

  1. Get an API key (one call, free credits included, no captcha):
curl -X POST https://sibfly.com/api/v1/autonomous/register \
     -H "Content-Type: application/json" -d '{"email":"you@example.com"}'

Save the returned apikey (shown once). Or skip this step: connect without a key and call the registeragent tool from inside MCP.

  1. Add the server to your MCP client config (Cline: MCP Servers → Remote Servers, or clinemcpsettings.json):
{
     "mcpServers": {
       "sibfly": {
         "type": "streamableHttp",
         "url": "https://sibfly.com/mcp",
         "headers": { "Authorization": "Bearer sf_live_YOUR_KEY" }
       }
     }
   }

OAuth 2.1 (Dynamic Client Registration + PKCE) is also supported for clients that prefer a "Connect" flow — discovery at /.well-known/oauth-authorization-server.

  1. Try it: call getcoverage (free) on any US address, then checkgroundmotion ($0.40, misses free). dryrun: true previews coverage, cost, and expected answer quality without billing. Out of credits? The buy_credits tool returns a payment link (card or crypto).

Sandbox: register with {"mode":"test"} for an sftest key — $100 fake credits, synthetic data, rehearse the whole flow for $0.

Use cases

Real-estate due diligence · "is my house sinking?" for home buyers · insurance & mortgage underwriting screening · infrastructure and portfolio subsidence monitoring · geotechnical pre-screening.

A product of SIB Scientific. Screening estimate from satellite radar (NASA OPERA / Sentinel-1 InSAR) — not an engineering, survey, or hazard determination.
