Frequently asked questions

Are these APIs free to use?

RHINO provides free, unlimited access to testnet APIs. For mainnet, these interfaces are rate limited to 50,000 requests per 24 hour period. If it is determined that these interfaces are being abused in testnet, the RHINO team will ban IP addresses, or enforce rate-limiting keys in the future. All rate limits subject to change.

What if my project needs more requests per day?

Reach out to a member of the RHINO team using the Contact Us section below, email, or schedule a meeting with us. We can provide pricing for unlimited use of these services.

Do you offer a SLA?

Absolutely! RHINO is looking to build the largest and most resilient Sei RPC infrastructure in the industry. This robust API stack uses a 3-tier architecture with multiple layers of redundancy.

We include an SLA in our agreement for unlimited network use.

How do I implement authorization to bypass the rate limiter?
