--- title: "Embeddings, rerank, transcription and Batch API" canonical: https://relayswitch.io/features/endpoints generated: 2026-11-02T10:15:20.870Z source: https://api.relayswitch.io/v1/catalog base_url: https://api.relayswitch.io/v1 --- Endpoints # Embeddings, rerank, audio, image edits and batch on one key. The OpenAI endpoints an agent stack needs beyond chat, on the same key, balance and limits. Memory, retrieval, voice notes, product shots and overnight jobs, priced live from the catalog. [Get an agent key](https://app.relayswitch.io/console)[Code](#example) From the live catalog Embedding models 11 Embeddings from $0.024 / M tokens Rerank models 1 Transcription models 3 Transcription from $0.0013 / minute Image edit models 43 Batch API 50% of the catalog price ## What it does for an agent Embeddings 11 models on POST /v1/embeddings for agent memory and retrieval, priced per million input tokens. Rerank POST /v1/rerank in Cohere and Jina’s shape: up to 1,000 documents scored against a query, best first. Transcription and translation OpenAI’s audio endpoints on Whisper and Parakeet models, billed per audio minute to the second. Image edits POST /v1/images/edits with files or URLs, on the image models that edit. Moderation POST /v1/moderations returns OpenAI’s moderation object, for checking what an agent is about to post. Batch API Upload JSONL to /v1/files, run it with /v1/batches within 24 hours at half the catalog rate, download the output file. ## Copy, paste, run OpenAI SDK: embeddings and rerank python 1`from openai import OpenAI` 2`import os` 3 4`client = OpenAI(` 5 `base_url="https://api.relayswitch.io/v1",` 6 `api_key=os.environ["RELAYSWITCH_API_KEY"],` 7`)` 8 9`vectors = client.embeddings.create(` 10 `model="bge-base-en-v1.5",` 11 `input=["refund policy", "shipping times", "warranty claims"],` 12`)` 13`print(len(vectors.data[0].embedding))` 14 15`# Rerank: Cohere and Jina's shape, on the same key.` 16`import httpx` 17`ranked = httpx.post(` 18 `"https://api.relayswitch.io/v1/rerank",` 19 `headers={"Authorization": f"Bearer {os.environ['RELAYSWITCH_API_KEY']}"},` 20 `json={"model": "bge-reranker-base", "query": "How long do refunds take?",` 21 `"documents": docs, "top_n": 5},` 22`).json()["results"]` OpenAI SDK: transcription python 1`from openai import OpenAI` 2`import os` 3 4`client = OpenAI(` 5 `base_url="https://api.relayswitch.io/v1",` 6 `api_key=os.environ["RELAYSWITCH_API_KEY"],` 7`)` 8 9`with open("standup.m4a", "rb") as f:` 10 `text = client.audio.transcriptions.create(` 11 `model="whisper-large-v3-turbo",` 12 `file=f,` 13 `response_format="text",` 14 `)` 15`print(text)` 16 17`# Any language into English text:` 18`# client.audio.translations.create(model="whisper-large-v3-turbo", file=f)` OpenAI SDK: image edit python 1`from openai import OpenAI` 2`import os` 3 4`client = OpenAI(` 5 `base_url="https://api.relayswitch.io/v1",` 6 `api_key=os.environ["RELAYSWITCH_API_KEY"],` 7`)` 8 9`result = client.images.edit(` 10 `model="gpt-image-1.5-edit",` 11 `image=open("product.png", "rb"),` 12 `prompt="Put the bottle on a marble counter, soft morning light",` 13`)` 14`print(result.data[0].url)` OpenAI SDK: Batch API python 1`from openai import OpenAI` 2`import os` 3 4`client = OpenAI(` 5 `base_url="https://api.relayswitch.io/v1",` 6 `api_key=os.environ["RELAYSWITCH_API_KEY"],` 7`)` 8 9`# requests.jsonl, one line per request:` 10`# {"custom_id": "t-1", "method": "POST", "url": "/v1/chat/completions",` 11`# "body": {"model": "...", "messages": [...]}}` 12`upload = client.files.create(file=open("requests.jsonl", "rb"), purpose="batch")` 13`job = client.batches.create(` 14 `input_file_id=upload.id,` 15 `endpoint="/v1/chat/completions",` 16 `completion_window="24h",` 17`)` 18`done = client.batches.retrieve(job.id)` 19`if done.status == "completed":` 20 `print(client.files.content(done.output_file_id).text)` curl: moderation bash 1`curl https://api.relayswitch.io/v1/moderations \` 2 `-H "Authorization: Bearer $RELAYSWITCH_API_KEY" \` 3 `-H "Content-Type: application/json" \` 4 `-d '{"input": "text an agent is about to post"}'` 5`# results[0].flagged, categories, category_scores` ## Embedding and rerank models USD per million input tokens, live. | Model | Type | Input | | --- | --- | --- | | `bge-base-en-v1.5` | embedding | $0.1665 | | `bge-en-icl` | embedding | $0.0313 | | `bge-m3` | embedding | $0.0295 | | `bge-small-en-v1.5` | embedding | $0.0505 | | `gemini-embedding-001` | embedding | $0.15 | | `multilingual-e5-large-instruct` | embedding | $0.0313 | | `qwen3-embedding-0.6b` | embedding | $0.0295 | | `qwen3-embedding-8b` | embedding | $0.0313 | | `text-embedding-3-large` | embedding | $0.13 | | `text-embedding-3-small` | embedding | $0.024 | | `text-embedding-ada-002` | embedding | $0.12 | | `bge-reranker-base` | rerank | $0.0078 | ## Transcription models USD per audio minute, live. | Model | Developer | Per minute | | --- | --- | --- | | `parakeet-tdt-0.6b-v3` | NVIDIA | $0.015 | | `whisper-large-v3` | OpenAI | $0.015 | | `whisper-large-v3-turbo` | OpenAI | $0.0013 | ## Image edit models From the lowest tier, USD per image, live. | Model | Developer | From | | --- | --- | --- | | `gpt-image-1.5-edit` | OpenAI | $0.0125 | | `kling-o3-image-edit` | Kling | $0.0219 | | `kling-o1-image-edit` | Kling | $0.0219 | | `gpt-image-2-edit` | OpenAI | $0.024 | | `nano-banana-edit` | Google | $0.0313 | | `nano-banana-2-lite-edit` | Google | $0.0313 | | `seedream-5.0-lite-edit` | ByteDance | $0.0313 | | `seedream-4.5-edit` | ByteDance | $0.0313 | | `flux-3-klein-edit` | Black Forest Labs | $0.036 | | `nano-banana-2-edit` | Google | $0.0402 | | `muse-image-edit` | Meta | $0.044 | | `qwen-image-edit` | Alibaba | $0.05 | Agent setup guides -
