The official API clients are covered by Algolia's [Service Level Agreement](https://www.algolia.com/policies/sla). For more information, see [Algolia's ecosystem](https://www.algolia.com/doc/libraries). ## Base URLs The Advanced Personalization API can be reached from multiple domains, each specific to a region. - `https://ai-personalization.eu.algolia.com` - `https://ai-personalization.us.algolia.com` Use the URL that matches your [analytics region](https://dashboard.algolia.com/account/infrastructure/analytics). **All requests must use HTTPS.** ## Authentication Add these headers to authenticate requests: - `x-algolia-application-id`. Your Algolia application ID. - `x-algolia-api-key`. An API key with the `search`, `browse` and `recommendation` ACL permissions. You can find your application ID and API key in the [Algolia dashboard](https://dashboard.algolia.com/account/api-keys). ## Request format Request bodies must be JSON objects. ## Response status and errors The Advanced Personalization API returns JSON responses. Since JSON doesn't guarantee any specific ordering, don't rely on the order of attributes in the API response. Successful responses return `2xx` statuses. Client errors return `4xx` statuses. Server errors return `5xx` statuses. Error responses have a `message` property with more information. ## Rate limiting When making requests to the Advanced Personalization API, you are limited to 500 API calls per minute per application. The following headers provide information about your current limit: - `x-ratelimit-limit`: The number of requests allowed every 60 seconds. - `x-ratelimit-remaining`: The number of requests remaining in the current 60 second period. - `x-ratelimit-reset`: Timestamp when the next time period starts, measured in seconds since the Unix epoch. ## Version The current version of the Advanced Personalization API is version 2, indicated by the `/2/` in each endpoint's URL. version: 2.0.0 servers: - url: https://ai-personalization.{region}.algolia.com variables: region: description: > Use the URL that matches your [analytics region](https://dashboard.algolia.com/account/infrastructure/analytics). enum: - eu - us default: eu security: - appId: [] apiKey: [] tags: - name: config x-displayName: Configuration description: > Manage your Advanced Personalization configuration.
