Locus: Traffic Crash Context
x402
Locus: Traffic Crash Context is a paid API for AI agents from api.locus.report, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).
Retrieves traffic crash records near a given address or coordinates across configurable radii and lookback periods to inform property due diligence.

How this service works
Returns small-cell-suppressed crash-count aggregates near an address, with explicit severity classes, for agents checking crash context. Returns the same records as locus_traffic_crash_context. Use this when your client can only call paid x402 routes. Use locus_traffic_crash_context instead when you can call Locus free tools (REST tools/call or MCP).
Output
Returns a JSON object with a record ID, a list of local traffic crash records near the queried location, caveats about data coverage and completeness, and a timestamp indicating when the report was generated. Open questions and gaps in public-record coverage are flagged for follow-up.
Example use cases
Pre-purchase road safety check
“I'm about to make an offer on a house at 88 Maple Street, Austin TX. Can you pull the crash records around it — 200, 500, and 1000 meter radii — going back 5 years so I can see how accident-prone that stretch is?”
Commercial site risk assessment
“We're considering leasing a retail space at 1400 Harbor Blvd, Fullerton CA. Run the Locus crash context scan within 500 meters looking back 3 years so we can assess pedestrian and vehicle accident history before signing.”
Neighborhood safety research
“I want to understand the traffic safety situation near 35.6895° N, 139.6917° E — can you check crash records within 200 and 1000 meters over the last 2 years?”
Technical details
Endpoint
POSThttps://api.locus.report/api/locus-traffic-crash-context?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need geospatially bounded, radius-configurable traffic crash history around a specific address or coordinate pair as part of property research or location risk assessment. It is specifically designed for pre-decision due diligence workflows and surfaces coverage gaps explicitly, making it more useful than generic public-record scrapers when you need to know not just what data exists but what remains unverified.
Side effects
- Address not parseable or too short — validation error returned
- Coordinates out of valid range (-90 to 90 lat, -180 to 180 lon) — schema rejection
- No crash records found for location — empty records array with caveats
- Payment not completed (x402 flow not resolved) — 402 response blocking data return
- Radii values outside 200–1000m range or more than 3 items — input validation failure
- Lookback years outside 1–10 range — validation error
