|---|---|---|
| Type | Ongoing free tier · perpetual | Trial credit · trial-credit |
| What's free | Free crowdsourced text & image generation; anonymous API key '0000000000' (no registration), or register to earn kudos for priority | 10M free tokens (one-time) across all models — embeddings, rerankers, classifier; plus a keyless Reader (r.jina.ai) for basic use |
| Rate limits | Queue-based priority via kudos (no fixed quota); anonymous requests get lowest priority under load | Free key: 100 RPM / 100k TPM for embeddings & reranker; Reader 20 RPM keyless, 500 RPM with a free key |
| Expires | no expiry | no expiry |
| The catch | Community-powered volunteer network — model availability and speed vary with worker supply, so it is not a fixed-SLA service. No card, no phone. Kudos never expire and cannot be sold. | 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. |
