§ CONTINUOUS SURVEY · STRUCTURED DATA
Aranea
The data API.
Hard-to-get web data, surveyed continuously and served through one clean API — one schema, delta polling, version history. First datasets: real-estate listings from Serbia's largest property portals.
§ WHAT THE SURVEY RETURNS
Data normalized to one schema
- Canonical fields
- Typed fields with one shape regardless of origin — in the real-estate datasets: price, area, rooms, floors, location, coordinates.
- Delta polling
- Ask for what changed since your last visit with
updated_sinceand a cursor. No re-downloading the world. - Version & price history
- Every client-visible change is versioned. Follow a record — or a price — over its whole life.
- Entity matching
- The same thing published in two places is linked to one entity, with match scores you can inspect.
- Documented surface
- An integration guide that walks from key to live sync, over an OpenAPI reference generated from the code that serves it — both readable before you hold a key.
§ ACCESS PROCEDURE
How access works
-
Apply
Send the form below. It takes a name, an email, and — if you like — what you're building.
-
Review
An operator reads every application. This is deliberate: access is granted per source, to named clients.
-
Integrate
Approved clients receive an API key directly from us, shown once. From there it's
Authorization: Bearerand the integration guide.
