All four products use a single scheme: a product-scoped API key passed in the x-cle-api request header. Keys are prefixed rf_ and are not interchangeable across products (a Places key cannot call Jobs). A missing or unknown key returns 401. Verified live: an unauthenticated GET returns HTTP 401 with body {"error":"clé absente — la présenter dans l'en-tête x-cle-api"}. docs: https://rankfabrik.com/documentation schemes: - id: api_key type: apiKey in: header name: x-cle-api key_prefix: rf_ scope: per-product (key is bound to one of Places/Jobs/Captions/Verify) description: >- Product-scoped secret API key issued at signup (free trial key delivered immediately, no card).
