How this service works
USGS ASCE 7 seismic design values for a US point: Ss, S1, SDS, SD1, seismic design category, and PGA, for a US address or coordinates. Optional reference document, risk category, and site class.
Output
Returns USGS ASCE 7 seismic parameters for the queried US location: short-period spectral acceleration (Ss), 1-second spectral acceleration (S1), design spectral accelerations (SDS, SD1), peak ground acceleration (PGA), and the seismic design category — all derived from the specified ASCE 7 reference document version, site class, and risk category.
Example use cases
Building code compliance check
“I need to verify our new office building in Seattle meets current seismic code requirements. Can you get me the ASCE 7-22 design values and seismic category for 1201 3rd Avenue, Seattle, WA using site class C?”
Retrofit project seismic assessment
“We're retrofitting a hospital in Los Angeles and need the latest ASCE 7 parameters for risk category IV. Pull the Ss, S1, SDS, SD1, and PGA values for 900 Olive View Drive, Los Angeles, CA, assuming site class D foundation conditions.”
Multi-site structural analysis
“Our firm is designing a data center campus across three locations. Can you get the ASCE 7-22 seismic design category and spectral acceleration values for these coordinates — I need Ss, S1, and SDS for each: 37.7749, -122.4194 in San Francisco; 34.0522, -118.2437 in Los Angeles; and 32.7157, -117.1611 in San Diego, all assuming site class B?”

Endpoint
GEThttps://api.agentstools.dev/hazard/seismic?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official USGS-sourced ASCE 7 seismic design parameters for structural engineering, building code compliance, or hazard assessment at a specific US location. It is the right choice when you need specific values like Ss, S1, SDS, SD1, PGA, or seismic design category as required by ASCE 7-10, 7-16, or 7-22 standards. Prefer this over general seismic hazard APIs when you need code-ready design values with support for site class and risk category adjustments.
Side effects
- Address outside the US or not geocodable returns an error
- Invalid or out-of-range latitude/longitude values return a validation error
- Neither address nor lat/lon provided causes a missing required parameter error
- Unsupported ASCE 7 reference document version returns an enum validation error
- Invalid site class or risk category enum value returns a bad request error
- Network or upstream USGS data source unavailability causes a 5xx error
