Gemini Embedding 2 Serverless API
Natively multimodal embeddings — text, image, audio, video and PDF mapped into one vector space, with 8 task-specific modes.

https://api.segmind.com/v1/gemini-embedding-2Parameters
inputrequiredstringText string to embed; supports up to ~8,192 tokens. Use shorter, focused sentences for best retrieval accuracy.
"Segmind provides fast and affordable AI model APIs for image generation, video creation, and more."audiooptionalstring (uri)Optional audio file to embed (URL or base64). MP3/WAV, up to 180 seconds.
imageoptionalstring (uri)Optional image to embed into the same vector space as text (URL or base64). PNG/JPEG; up to 6 per request via the `images` array. Combined with `input` text into one aggregated vector.
output_dimensionalityoptionalintegerTruncates vector length; 768 balances quality and storage. Use 256-512 for speed-sensitive pipelines.
768pdfoptionalstring (uri)Optional PDF file to embed (URL or base64). 1 file, up to 6 pages.
task_typeoptionalstringOptimizes embedding direction for your use case. Use RETRIEVAL_DOCUMENT for corpus, RETRIEVAL_QUERY for user queries, SEMANTIC_SIMILARITY for pair comparison.

Response Type
Returns: Text/JSON
Asynchronous requests (v2)
Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.
- 1
POST /v2/gemini-embedding-2Submit — returns request_id, status_url, response_url
- 2
GET /v2/requests/{id}/statusPoll — until COMPLETED or FAILED
- 3
GET /v2/requests/{id}Result — final response body
Status states
- A FAILED request is served as HTTP 422 — the body still carries the error detail.
- An unknown or expired request_id returns HTTP 404.
- Results are retained for 1 hour, then expire.
- Content / RAI blocks surface as FAILED, not a separate state.
- Track completion by polling the status endpoint.
