Quick Launch
FloodPulse is a natural-hazard risk API for US addresses: one call returns the FEMA flood zone and 30-year flood odds, terrain, county extreme-heat history and FEMA National Risk Index wildfire, heat and storm ratings. Use it over REST, MCP or A2A.
Overview
What FloodPulse does
FloodPulse answers the natural-hazard questions behind real estate, insurance and infrastructure decisions for any US street address (or latitude and longitude).
- GET /v1/flood?address=... returns the FEMA flood zone and subtype, whether the address is in a Special Flood Hazard Area, the base flood elevation where FEMA maps one, the annual and 30-year flood odds, elevation and height above nearest drainage, and the FEMA National Risk Index inland and coastal flooding ratings for the census tract.
- GET /v1/wildfire?address=... returns the FEMA National Risk Index wildfire rating, national percentile, annual burn probability and expected annual loss for the census tract.
- GET /v1/heat?address=... returns the county's days over 90F and 95F per year from NOAA nClimGrid-Daily, 1981-2024: the 1991-2000 vs 2015-2024 change, the trend per decade, the hottest year and the record high, plus the FEMA NRI heat-wave rating (contiguous US only).
- GET /v1/report?address=... combines flood, wildfire, heat and storm (tornado, hail, strong wind, hurricane) with the FEMA NRI composite rating and national percentile.
- GET /v1/compare?addresses=A|B|C compares 2-3 addresses side by side: flood zone, 30-year flood odds and FEMA NRI composite and per-hazard ratings.
Where the data comes from
Flood zones come from the FEMA National Flood Hazard Layer (a point's zone is cached up to 30 days, as flood maps change rarely). Hazard ratings come from the FEMA National Risk Index (census tract, cached up to 30 days; the release used is in every response). Terrain comes from the Copernicus GLO-30 DEM and the Global 30m Height Above Nearest Drainage dataset, and heat history from NOAA nClimGrid-Daily county averages, all on the Registry of Open Data on AWS. Addresses are geocoded with the US Census Geocoder. Every response lists the sources it used, with their notices and retrieval times, in data_sources. If a source is unavailable the API answers 503 and the call is not billed.
- This product uses the Federal Emergency Management Agency's National Risk Index dataset API or downloadable datasets but is not endorsed by FEMA. The Federal Government or FEMA cannot vouch for the data or analyses derived from these data after the data have been retrieved from the Agency's website(s). Dataset: FEMA National Risk Index, census tracts (https://hazards.fema.gov/nri/ ); the release used and the retrieval time are in each response's data_sources.

Three ways to connect
- REST with an X-API-Key header, described by an OpenAPI 3 schema (https://floodpulse.waltsoft.net/openapi.json ).
- MCP: the tool floodpulse___floodpulseQuery (path /v1/report, /v1/flood, /v1/wildfire, /v1/heat or /v1/compare) on the Amazon Bedrock AgentCore Gateway, for Claude, Strands Agents and other MCP clients.
- A2A (Agent2Agent 0.3): the agent card at https://floodpulse.waltsoft.net/.well-known/agent-card.json with the skills getFullReport, getFloodRisk, getWildfireRisk, getHeatRisk and compareAddresses.
Who it is for
Real estate and mortgage platforms, insurance underwriting and quoting tools, property due-diligence agents and infrastructure planners that need authoritative US hazard data for an address in one call.
Billing
On AWS Marketplace every successful call is one unit at $0.25, any route, on your AWS bill. Errors (400, 401, 404, 429, 503) are never billed. Heat history returns 404 for Alaska and Hawaii (NOAA nClimGrid covers the contiguous US only). Rate limit: 50 requests per second, bursts up to 100.
Highlights
- Five hazard endpoints: FEMA flood zone and 30-year flood odds with terrain, FEMA NRI wildfire rating, NOAA county extreme-heat history, a full multi-hazard report and a 2-3 address comparison
- Public US government and open data with every credit in each response: FEMA NFHL and National Risk Index, NOAA nClimGrid-Daily, Copernicus GLO-30 and HAND; a source outage returns 503 and is never billed
- Agent-ready: REST with an OpenAPI 3 schema, an MCP tool on Amazon Bedrock AgentCore Gateway and an A2A agent card; one Marketplace unit ($0.25) per successful call

Usage instructions
To get started using the remote MCP server, follow the instructions below:
Available Tools This MCP server (Amazon Bedrock AgentCore Gateway) supports the following tool:
- floodpulse___floodpulseQuery - Natural-hazard risk for a US address. Arguments: path (one of /v1/report, /v1/flood, /v1/wildfire, /v1/heat, /v1/compare), address (or lat and lon), addresses (for /v1/compare: 2-3 US addresses separated by |), api_key
Prerequisites
- An active subscription to this product. Your API key (it starts with mp_) is stored in your AWS Secrets Manager after you choose Set up your account, and is also shown on the registration page.
- Install Node.js and npm (for mcp-remote), or Python 3.10+ (for the Strands Agents SDK).
Authentication The MCP endpoint needs no connection header. Pass your key as the api_key argument of every tool call; replace YOUR_API_KEY with your actual key below. A wrong or inactive key returns a 401 error body.
MCP endpoint: https://waltsoft-marketplace-gateway-xncyjgs1uh.gateway.bedrock-agentcore.us-east-1.amazonaws.com/mcp
