Plans
Surflux offers flexible pricing tiers designed to scale with your application, from prototyping to enterprise-grade production. All plans provide full access to our APIs, with differences in credits, rate limits, and concurrent streams.
Quick Start
Standard Plans
All plans include access to the full Surflux platform: NFT Indexing API, DeepBook Indexing API, Flux Streams, and gRPC. Your choice of tier determines your monthly credit allowance, rate limits, and number of concurrent streams.

Frequently Asked Questions
Can I upgrade or downgrade my plan?
Yes. Upgrades take effect immediately with prorated billing. Downgrades take effect at the start of your next billing cycle.
What happens if I exceed my rate limits?
Requests that exceed your RPS cap will receive HTTP 429 responses. Consider upgrading to a higher tier or spreading requests over time.
Do unused credits roll over?
No. Credits reset monthly on your billing anniversary. Enterprise plans can negotiate custom terms.
Can I purchase additional credits without upgrading?
Not on standard plans. Enterprise plans can negotiate prepaid credit packages.
How are concurrent streams counted?
Each active Flux Stream connection counts toward your limit. If you disconnect and reconnect, it still counts as one stream. Multiple streams to the same endpoint count separately.
