Gemini Embedding 2 Serverless API

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

API Endpoint

POSThttps://api.segmind.com/v1/gemini-embedding-2

Parameters

inputrequired
string

Text string to embed; supports up to ~8,192 tokens. Use shorter, focused sentences for best retrieval accuracy.

Default: "Segmind provides fast and affordable AI model APIs for image generation, video creation, and more."
audiooptional
string (uri)

Optional audio file to embed (URL or base64). MP3/WAV, up to 180 seconds.

imageoptional
string (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_dimensionalityoptional
integer

Truncates vector length; 768 balances quality and storage. Use 256-512 for speed-sensitive pipelines.

Default: 768
pdfoptional
string (uri)

Optional PDF file to embed (URL or base64). 1 file, up to 6 pages.

task_typeoptional
string

Optimizes embedding direction for your use case. Use RETRIEVAL_DOCUMENT for corpus, RETRIEVAL_QUERY for user queries, SEMANTIC_SIMILARITY for pair comparison.

Default: "RETRIEVAL_DOCUMENT"
Allowed values :
"SEMANTIC_SIMILARITY""RETRIEVAL_DOCUMENT""RETRIEVAL_QUERY""CLASSIFICATION""CLUSTERING""QUESTION_ANSWERING""FACT_VERIFICATION""CODE_RETRIEVAL_QUERY"
videooptional
string (uri)

Optional video file to embed (URL or base64). MP4/MOV, up to 120 seconds.

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. 1
    POST /v2/gemini-embedding-2

    Submitreturns request_id, status_url, response_url

  2. 2

Status states

QUEUEDAccepted, waiting for a worker
PROCESSINGRunning on a worker
COMPLETEDDone — result body is ready
FAILEDErrored (incl. content/RAI blocks)
  • 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.
