Description
Create account to comment on specific lines or Sign in
+ 1 Jina AI gives every new user 10 million free tokens via an auto-generated API key — no credit card required. The same key works across all Search Foundation products: Embeddings, Reranker, Reader, Classifier and Fine-tuning. Tokens are pooled, so you decide how to spend them. Reader API even works without any key at all at reduced rate limits — useful for one-off URL-to-Markdown conversions in agents and RAG pipelines.

+ 10 4. (Optional but recommended) Click "API Key + Billing" in the top nav and sign in — Google login or email — to permanently associate the key with your account; otherwise the auto-key is only tied to your browser/IP and you can lose it

+ 14 • No credit card required for the 10M free tokens
No comments on this line yet.
+ 15 • The 10M tokens are shared across every Search Foundation API (one wallet, many APIs)
No comments on this line yet.
+ 16 • After 10M tokens are used, you must top up — packages start small (no monthly subscription required)

+ 17 • An anonymous auto-generated key is tied to your browser/IP — sign in to make it portable

18
• Reader API works without ANY key for casual use (20 RPM); the Search endpoint (s.jina.ai) requires a key

+ 85 • Embeddings (jina-embeddings-v3, ~512 tokens/chunk avg): ~20,000 chunks embedded — easily covers a personal RAG over a mid-size knowledge base

+ 86 • Reranker: Plenty of headroom; rerank operations are short query+doc pairs (~200-1K tokens each)
No comments on this line yet.
+ 87 • Reader: Each URL → markdown call typically returns 1K-5K tokens; you get 2,000-10,000 page conversions before hitting the limit
No comments on this line yet.
+ 88 • Classifier: Cheapest per call; zero-shot label scoring uses a few hundred tokens per request

• The Reader endpoint is the easiest "free LLM tool" in Jina's lineup — just curl https://r.jina.ai/https://example.com with no auth and you get back clean markdown for any web page

+ 95 • Pair Jina embeddings with Voyage AI's 200M free tokens or Cohere's free trial to compare quality on your domain before committing
No comments on this line yet.
+ 96 • Jina is EU-based (Berlin HQ) — useful if you need a non-US embedding provider for compliance reasons
No comments on this line yet.
+ 97 • The 10M token allowance is per account, not per month — once spent, it's spent (no automatic monthly refill on the free tier)
No comments on this line yet.
+ 98 • The auto-generated browser key is convenient for quick experiments but always upgrade to a signed-in account key before putting anything into production
