Sampled — shipped under file-level sampling, not individually fact-checked community attestations: 0✓ / 0✗
Steps Request a free API token via the 511.org Open Data token request page Call the traffic/events endpoint with your api_key, filtering by status (ACTIVE vs ALL) and geographic bounding box as needed Parse returned Open511-formatted event records for incident type, severity, geometry, and timestamps Respect the documented default rate limit of 60 requests per 3600 seconds per token Consult the published technical specification PDF for the full parameter and field reference Known gotchas Coverage is limited to the nine-county San Francisco Bay Area - this is a regional, not national, API Exceeding the 60 requests/hour default limit requires emailing the developer group for an increase, not a self-serve quota bump 511.org's own documentation asks developers not to include their API key when emailing support for help
