Rate limit: 10 requests per second per workspace. Find the technologies used by one website, such as its CMS, analytics tools, or JavaScript frameworks. Authenticate with your Airscale workspace API key and send exactly one `domain` field containing a bare hostname or HTTP(S) URL. The domain is normalized to lowercase without a leading `www.` or trailing dot. Paths and queries are ignored. IP addresses, localhost, URL credentials, non-default ports, and non-HTTP(S) schemes are rejected. The JSON body must fit within **16 KiB**; additional fields are not accepted. ## Usage and credits You need at least **0.5 credits** before a lookup can start. A response with one or more technology names costs **0.5 credits**. An empty result returns `technologies: []` and `credits_consumed: 0`. Read `domain` for the normalized hostname and `technologies` for the list of names. Duplicate names are removed without regard to case. An empty list means no technologies were found for that lookup; it does not prove the website uses no technologies. ## Rate limits and retries The limit is **10 requests per second per workspace**, measured in fixed UTC-second windows. Lookup capacity is also shared across workspaces, so actual throughput can be lower. A workspace rate limit returns `429`; unavailable lookup capacity returns `503`. Allow more than **60 seconds** for a request: the lookup itself can take up to 60 seconds, with additional time for authentication and billing. A failed or timed-out lookup returns `502`. Authentication or billing services can also return `503`. Use bounded backoff for temporary errors. This endpoint does not support caller idempotency keys. Retrying can run and charge another lookup, including when the original response was lost. A client timeout does not confirm that no credits were charged. ## Next step Check your [credit balance](/api-reference/credit-count) or review [rate limits](/api-reference/rate-limits) before scheduling more lookups. ## OpenAPI ````yaml openapi.json POST /v1/technologies openapi: 3.1.0 info: title: Airscale Public API version: '2026-09-11' description: Search, enrich, and resolve public business data with Airscale. x-airscale-source-repository: ViceScale/airscale-code x-airscale-source-sha: 1de19e1b70a052a4b8d9c2075021a7e5e7a94d51 servers: - url: https://api.airscale.io description: Production security: - bearerAuth: [] tags: - name: Search and discovery description: Search people, companies, and the web. - name: Contact data description: Find professional and personal contact data. - name: Profiles and reverse lookup description: Extract profiles or resolve a person from known contact data. - name: Post engagement description: Retrieve and enrich people who liked or commented on LinkedIn posts. - name: LinkedIn content description: >- Search LinkedIn posts, read profile and company feeds, and retrieve profile comments and comment reactions. - name: Account description: Inspect workspace account state. - name: Miscellaneous description: >- Find website technologies and check WhatsApp availability, Meta ads, and email deliverability. paths: /v1/technologies: post: tags: - Miscellaneous summary: Find website technologies description: >- Find technology names for one website.
