2s Location Dossier API
x402
2s Location Dossier API is a paid API for AI agents from 2s.io, paid per call via x402, $0.0072/call, status unknown (last checked 2026-09-13).
Returns a comprehensive geo-risk dossier for a US location including flood zone, seismic category, climate station, place identity, and optional demographics.

How this service works
Static risk & context dossier for a US location. Pass lat+lon or a US address (geocoded for you). Composes five authoritative, keyless federal sources into one answer an agent cannot derive from training: Census place context (county, state, census tract, congressional district), FEMA flood zone + Special-Flood-Hazard-Area status, USGS ASCE 7-16 seismic design parameters (Ss, S1, SDS, SD1, seismic design category, PGA), the nearest NOAA/GHCN climate station, and — when a zip is supplied — US Census ACS 5-year demographics. Each layer is isolated: one source failing does not fail the rest. This is the slow-moving structural-risk picture (siting, insurance, due diligence), distinct from real-time weather/earthquake conditions.
Output
A JSON object containing: flood zone code, SFHA boolean, and risk level; state and county; seismic design category (e.g. 'D') and spectral acceleration per ASCE7-16; nearest climate station ID and distance in km; optional ACS population; plus a top-level summary object consolidating key fields. Each sub-section includes a found/error flag.
Example use cases
Example prompt
“Pull the full location dossier for 1600 Amphitheatre Parkway, Mountain View, CA — I need flood zone, seismic design category, nearest climate station, and county info, and include ACS demographics for ZIP 94043.”
Technical details
Endpoint
GEThttps://2s.io/api/geo/location-dossierWhen to prefer
Use this endpoint when you need a single-call, multi-source geo-risk snapshot for a US location covering flood, seismic, climate, and place identity together. Prefer over piecing together individual FEMA, USGS, or Census calls when you need a quick aggregated dossier at low cost ($0.0072 USDC). Ideal for real estate underwriting, site selection, AI-driven property analysis, or any workflow needing authoritative US hazard data without API key management.
Side effects
- Address cannot be geocoded — place.found=false with error message
- Coordinate falls outside US coverage — flood or seismic data not found
- Invalid lat/lon format — returns 400 or empty results
- ZIP not provided — demographics section omitted (not an error)
- FEMA or USGS source temporarily unavailable — individual section found=false with error
