Seismic design data (USGS NEHRP 2020)

Returns USGS NEHRP-2020 / ASCE 7 parameters at a point (Ss, S1, PGA, SDS, SD1, and Seismic Design Category) for an assumed default site class, for engineering agents. Cited hazard data for a design check. Not a safety, risk, or safe/unsafe judgment. National. Read-only. Use this when you can call Locus free tools (REST tools/call or MCP). Use locus-seismic-design instead when your client can only call paid x402 routes; it returns the same records. Direct flat-body route for this one free resource; no API key, payment, or catalog wrapper. Return only the cited bounded evidence described here; this route never produces a paid brief or full report.
