ODN API
The Socrata OpenDataNetwork (ODN) REST API exposes public data, often continuosly updated and enhanced, from many thousands of public government and non profit agencies. Much of this data originating from independent sources is fused together to create new, and often powerful, entity level data. The API, in addition to search and autosuggest capabilities for finding datasets, enables data based comparisons across geographical regions such as states, counties, metropolitan areas, cities and zip codes using highly vetted data providers such as US Census, BEA, HUD and others. Comparison data is preformatted for easy and efficient display on a chart, graph or interactive map. The API also exposes data organized by narrative style questions a human might ask. The questions can be rapidly found using an autosuggest style index, and then used to directly access all data needed to thoroughly and authoritatively answer the question. Retrieved data includes time series (temporally aligned), tabular, map heavy (includes spatial boundaries), and auto generated unstructured descriptive text. The ODN API does not duplicate API endpoints or services provided by public sector agencies, but rather,
Plan the first integration safely
The access fields below come from the connected directory. Their likely implementation impact is explained without assuming provider-specific behavior.
Authentication
OAuth is reported. Confirm flows, scopes, consent, token lifetime, and refresh rules.
Transport
HTTPS is not confirmed. Do not send credentials or production data until secure transport is verified.
Browser access
CORS is unknown. Treat direct browser access as unconfirmed and test before choosing a client-only architecture.
First-request sequence
- Identify the current base URL, version, and endpoint for the use case.
- Confirm how credentials are issued and where they may be stored.
- Test success, invalid input, throttling, unavailable data, and timeouts.
- Record response fields, pagination, caching, and error shapes.
- Add monitoring, retries with backoff, and an appropriate fallback.
Questions to resolve before production
Pricing and quotas
Confirm current plans, free-tier limits, overages, and request ceilings.
Endpoint coverage
Check that the operations and response fields match the intended workload.
Reliability
Look for uptime history, a status page, support routes, and service commitments.
Data and privacy
Review retention, licensing, regional processing, and compliance requirements.
Versioning
Confirm the active version, change policy, deprecation window, and migration guidance.
Developer experience
Validate SDKs, examples, error formats, pagination, and test environments.
