# Changes ## 1.2.0 - 24.10.2026 - A key is required for `/api/transport/`: a request without a key gets `401 KEY_REQUIRED`. A request with a wrong, revoked or another project's key is still refused and is never served as a request without a key. - The older addresses without `/transport` (for example `/api/stops/search`) still answer without a key for now (transition), with limits per address; their end will be announced in advance. With a key they are checked exactly like `/api/transport/`. - `X-RateLimit-Remaining` shows the real remainder of the current minute (it was always `0`). ## 1.1.0 - 22.10.2026 - Access by key: integrations send the key of an approved project as `Authorization: Bearer `. Applications, review, keys, IP addresses and usage are in the [developer cabinet](https://app.ibusisrael.online/developers); see [how access works](/access/). - Limits belong to the project (per minute, day and month, at the same time, heavy operations) instead of one IP address. Refusals name the limit and link to [access errors](/docs/access/#codes). - New operation: `GET /api/access/whoami` shows what the server sees about your request. - Transition: published operations keep answering without a key, with limits per network, until a date announced in advance. - The reference no longer sends requests from the page. ## 1.0.0 - 21.10.2026 - `https://api.ibusisrael.online` is the canonical address of the iBus transport API. The gateway's paths are published under `/api/transport/`, with the same answers as `https://app.ibusisrael.online/api/transport/`, which keeps working. - First public description: 22 read-only operations in [openapi.json](https://api.ibusisrael.online/openapi.json), guides in four languages, [llms.txt](https://api.ibusisrael.online/llms.txt). - Limits are shared between both addresses. A limit hit answers JSON with `Retry-After`. - Known limitation: on the nights when clocks change, UTC fields computed from the timetable can differ by an hour for trips before 02:00 (see [data and time](/docs/data/#service-date)).
