Try any of 3860 endpoints — live.
Pick an endpoint, load a working example, tweak the params, and send — no signup to try. Results render the way the data deserves; raw JSON, headers & code are one tab away.
Rental buildings in a place. Give a `location` ('Austin, TX', '78704', 'Downtown Chicago'), or a `bounding_box`, or `latitude`+`longitude`+`radius_miles`. Each row is a BUILDING with one entry per bed count in `floor_plans` — that is how apartments.com publishes rent, and flattening it would lose the price signal. `total_units` is the source's own count of available UNITS in the box, which is a different measure from the number of buildings returned.
Where to search: a US city and state ('Austin, TX'), a ZIP code ('78704'), a neighbourhood ('Downtown Chicago') or a street address. Resolved to a map box before the search runs. Pass `bounding_box` or `latitude`+`longitude` instead if you already have coordinates.
An explicit map box as 'south,west,north,east' (or an object with lower_right / upper_left). Skips the location lookup entirely.
Centre latitude. Used with `longitude` and `radius_miles`.
Centre longitude. Used with `latitude` and `radius_miles`.
Half-height of the box drawn around `latitude`/`longitude`, in miles. (0.25–50)
How many buildings to return. The source serves 40 per page, so a larger limit costs one upstream page per 40. (1–200)
Which page of results to start from. (1–100)
Result order. This is applied BY THE SOURCE — the page echoes it back — unlike the filters below, which this API applies to the rows.
Keep buildings whose rent range reaches this monthly rent in USD. Applied by this API to the returned rows. A building that publishes no rent ('Call for Rent') cannot be confirmed to match, so it is left out whenever a rent filter is set. (0–)
Keep buildings whose cheapest published rent is at or below this. Applied by this API to the returned rows. Buildings with no published rent are left out. (0–)
Keep buildings offering at least this many bedrooms (0 = studio). Applied by this API. (0–6)
Keep buildings offering at most this many bedrooms. Applied by this API. (0–6)
Keep only buildings whose amenity list mentions pets. The full pet policy is not published on this surface.
Keep buildings whose amenity list contains all of these (case-insensitive substring match). Applied by this API to the short list the source publishes.
Keep only buildings with a 3D tour.
Keep only buildings with a video.
Keep only buildings advertising a move-in special (free months, discounts).

ReefAPI is one HTTP gateway to 632 live web-data APIs covering 3860 endpoints across 13 categories. Every endpoint answers with the same JSON envelope, so one integration reaches all of them. Each response reports what it cost and when the source was read.
No signup, no API key and no card are required to try an endpoint on this page. Anonymous calls run on a shared demo key, capped at 15 calls per hour per visitor. Pick an API, fill the parameters and the real response comes back from the live source, not from a canned sample. A free account lifts the cap and gives you 1,000 credits and your own key.
Browse every API in the catalog, read an endpoint's fields and example response in the docs, or see per-call credit costs on the pricing page.
