Free embeddings & rerank behind an OpenAI-compatible endpoint

What's free

10M free tokens (one-time) across all models — embeddings (v3/v4), rerankers, classifier; plus a keyless Reader (r.jina.ai) for basic use

Rate limits

Free key: 100 RPM / 100k TPM for embeddings & reranker (2 concurrent); keyless Reader 20 RPM

The catch

The 10M-token balance is a one-time grant that does not replenish; the keyless Reader is genuinely ongoing. Hosted API is commercial-OK and data is not used for training. No card required.

Quickstart — chat completions

from openai import OpenAI

client = OpenAI(base_url="https://api.jina.ai/v1", api_key="<YOUR_FREE_API_KEY>")
resp = client.chat.completions.create(
    model="<a-free-model>",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)

…or with curl:

curl https://api.jina.ai/v1/chat/completions \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"<a-free-model>","messages":[{"role":"user","content":"Hello!"}]}'
