The BeatAPI key is removed before forwarding. Reference: https://docs.beatapi.io/api-reference/gpt-5-6/text/generate-gemini-compatible-content ## Authentication - `x-goog-api-key` header (required) — Gemini-compatible API key header. Use a BeatAPI API key. - `Authorization` header (bearer token, required) — Send your API key as `Authorization: Bearer `. ## Request ### Path parameters - `model` (string, required) — Public text model id exposed by BeatAPI. Call GET /v1/models to discover the models enabled for your environment. - `action` (enum, required) - Allowed values: `generateContent`, `streamGenerateContent` ### Body (application/json) This endpoint expects a map from string to any. - `map from string to any` ## Response ### 200 Gemini-compatible JSON response or server-sent event stream - `map from string to any` ## Errors ### 400 Bad Request Error Malformed JSON or an unsupported field (`bad_request`), or input refused by moderation (`content_policy_violation`). Not retryable unchanged. - `TextError` ### 401 Unauthorized Error No API key (`missing_api_key`), or a key that is wrong, expired, disabled or exhausted (`invalid_api_key`). - `TextError` ### 402 Payment Required Error Insufficient balance (`insufficient_credits`). The account balance is zero or below the price of this request. - `TextError` ### 403 Forbidden Error The key or account is not permitted to use this model (`forbidden`), for example a model that is not available on free credit. - `TextError` ### 404 Not Found Error Unknown model (`not_found`). List the enabled models with `GET /v1/models`. - `TextError` ### 429 Too Many Requests Error Too many requests (`rate_limit_exceeded`, including the free-model limits). Retry after `Retry-After` seconds. - `TextError` ### 500 Internal Server Error Unexpected internal error (`internal_error`). Retryable. - `TextError` ### 503 Service Unavailable Error The request could not be completed (`processing_unavailable`, `processing_timeout` or `processing_failed`). Nothing was charged. Retry with backoff. - `TextError` ## Types ### OpenAITextError - `error` (OpenAiTextErrorError, required) ### AnthropicTextError - `type` ("error", required) - `error` (AnthropicTextErrorError, required) ### OpenAiTextErrorError - `message` (string, required) — English sentence that states the cause. - `type` (string, optional) - `code` (string, optional) — BeatAPI error code, for example `insufficient_credits` or `rate_limit_exceeded`. ### AnthropicTextErrorError - `type` (string, required) - `message` (string, required) — English sentence that states the cause. ## Examples **Request** ```json { "contents": [ { "parts": [ { "text": "Explain this architecture decision in three concise bullets." } ], "role": "user" } ] } ``` **Response** ```json {} ``` **SDK Code** ```python Text_generateGeminiCompatibleContent_example import requests url = "https://api.beatapi.io/v1beta/models/model:generateContent" payload = { "contents": [ { "parts": [{ "text": "Explain this architecture decision in three concise bullets." }], "role": "user" } ] } headers = { "x-goog-api-key": "", "Content-Type": "application/json" } response = requests.post(url, json=payload, headers=headers) print(response.json()) ``` ```javascript Text_generateGeminiCompatibleContent_example const url = 'https://api.beatapi.io/v1beta/models/model:generateContent'; const options = { method: 'POST', headers: {'x-goog-api-key': '', 'Content-Type': 'application/json'}, body: '{"contents":[{"parts":[{"text":"Explain this architecture decision in three concise bullets."}],"role":"user"}]}' }; try { const response = await fetch(url, options); const data = await response.json(); console.log(data); } catch (error) { console.error(error); } ``` ```go Text_generateGeminiCompatibleContent_example package main import ( "fmt" "strings" "net/http" "io" ) func main() { url := "https://api.beatapi.io/v1beta/models/model:generateContent" payload := strings.NewReader("{\n \"contents\": [\n {\n \"parts\": [\n {\n \"text\": \"Explain this architecture decision in three concise bullets.\"\n }\n ],\n \"role\": \"user\"\n }\n ]\n}") req, _ := http.NewRequest("POST", url, payload) req.Header.Add("x-goog-api-key", "") req.Header.Add("Content-Type", "application/json") res, _ := http.DefaultClient.Do(req) defer res.Body.Close() body, _ := io.ReadAll(res.Body) fmt.Println(res) fmt.Println(string(body)) } ``` ```ruby Text_generateGeminiCompatibleContent_example require 'uri' require 'net/http' url = URI("https://api.beatapi.io/v1beta/models/model:generateContent") http = Net::HTTP.new(url.host, url.port) http.use_ssl = true request = Net::HTTP::Post.new(url) request["x-goog-api-key"] = '' request["Content-Type"] = 'application/json' request.body = "{\n \"contents\": [\n {\n \"parts\": [\n {\n \"text\": \"Explain this architecture decision in three concise bullets.\"\n }\n ],\n \"role\": \"user\"\n }\n ]\n}" response = http.request(request) puts response.read_body ``` ```java Text_generateGeminiCompatibleContent_example import com.mashape.unirest.http.HttpResponse; import com.mashape.unirest.http.Unirest; HttpResponse response = Unirest.post("https://api.beatapi.io/v1beta/models/model:generateContent") .header("x-goog-api-key", "") .header("Content-Type", "application/json") .body("{\n \"contents\": [\n {\n \"parts\": [\n {\n \"text\": \"Explain this architecture decision in three concise bullets.\"\n }\n ],\n \"role\": \"user\"\n }\n ]\n}") .asString(); ``` ```php Text_generateGeminiCompatibleContent_example request('POST', 'https://api.beatapi.io/v1beta/models/model:generateContent', [ 'body' => '{ "contents": [ { "parts": [ { "text": "Explain this architecture decision in three concise bullets." } ], "role": "user" } ] }', 'headers' => [ 'Content-Type' => 'application/json', 'x-goog-api-key' => '', ], ]); echo $response->getBody(); ``` ```csharp Text_generateGeminiCompatibleContent_example using RestSharp; var client = new RestClient("https://api.beatapi.io/v1beta/models/model:generateContent"); var request = new RestRequest(Method.POST); request.AddHeader("x-goog-api-key", ""); request.AddHeader("Content-Type", "application/json"); request.AddParameter("application/json", "{\n \"contents\": [\n {\n \"parts\": [\n {\n \"text\": \"Explain this architecture decision in three concise bullets.\"\n }\n ],\n \"role\": \"user\"\n }\n ]\n}", ParameterType.RequestBody); IRestResponse response = client.Execute(request); ``` ```swift Text_generateGeminiCompatibleContent_example import Foundation let headers = [ "x-goog-api-key": "", "Content-Type": "application/json" ] let parameters = ["contents": [ [ "parts": [["text": "Explain this architecture decision in three concise bullets."]], "role": "user" ] ]] as [String : Any] let postData = JSONSerialization.data(withJSONObject: parameters, options: []) let request = NSMutableURLRequest(url: NSURL(string: "https://api.beatapi.io/v1beta/models/model:generateContent")!
