Read-only public APIs over the datasets behind our free tools. Every resource is a plain GET, needs no key, sets open CORS, and ships an OpenAPI 3.1 spec.
Built the way we build data systems on contract: versioned, documented, reconciled at the source, and honest about provenance. Each API below has its own docs, a live console you can run in the browser, and an importable spec.
Crime
42+ months of SAPD reported offenses by ZIP code, reconciled and served as JSON and CSV.
Stig Nist
DISA STIG rules mapped through DoD CCIs to NIST 800-53 controls, with a per-control lookup.
Nist 800 171
All 110 controls with the DoD Assessment Methodology weights used to compute a SPRS score.
Attribution
Every vessel on the OFAC sanctions list, resolved to the company behind it, with the evidence chain. Includes the links we refuse to resolve, and why.
Trail Access
Every San Antonio trail segment classified by surface firmness, the sidewalk network by council district, and an audit of the City inventory's own missing-data sentinels. Certifies nothing, and says why.
Permisos
Every San Antonio building permit by type, council district and month, published with the coverage rate of every field the totals are computed from.
Mixed Beverage
Nineteen years of alcohol sales for every permitted bar and restaurant in Bexar County, by month and ZIP, with a disclosure floor that protects single-venue ZIPs.
Conducción agresiva
SAPD driving-event calls, the City injury-crash record, and reports from residents. Three layers, published separately and never summed.
Plate Readers
Automated license plate readers mapped by volunteers in Bexar County. No agency publishes their locations, so this is a floor and not a census, and it carries no coverage rate.
Centros de datos
Data center sites in San Antonio, from the City permit record. The record has no category for a data center, so the count is a floor and every rejected candidate is published with the reason it failed.
Service Requests
Every 311 request the City publishes, scored against the deadline the City set for it and its own late flag. Deadlines run from same-day to three months and differ by request type, so a rate never appears without one.
Dc Zoning
How much San Antonio land would still be eligible for a data center under the proposed UDC amendment, citywide and by council district, with the answer at four setback distances. NOT ADOPTED: it scores a staff proposal that Council votes on in October 2026, and every response carries the criteria it was scored against.
Dc Corroboration
Not a count. Facilities in the federal environmental register that look like data centers near San Antonio, scored on whether the City permit record contains them. Many are the same places as data-centers above, so the overlap rides on every response and the two totals are never summed.
Bono
San Antonio voter-approved bond projects, published with the coverage rate of every money field (the Total and Bond field pairs are never mixed)
Dc Environment
What federal environmental regulators hold about San Antonio data centers, found by NAICS classification (registrations, not an inventory, and no power figure)
Registros de niños desaparecidos
Not a count of missing children, because no public record holds one. Texas DPS missing person entries for all 254 counties since 2020, the state report on children missing from foster care, and San Antonio police call counts, each with its unit. Nothing identifies a child, and no route takes a place or a name.
