How credits and request limits work
Credits and RPS answer different questions. Credits measure total usage over a month. Requests per second (RPS) measures how much traffic your application can send at once. A service can remain within its monthly credit budget and still hit an RPS ceiling during bursts. Conversely, a steady workload can remain under its RPS cap and still exhaust monthly credits over time.
| Limit | What it controls | When it is too small |
|---|---|---|
| Credits / month | Total sustained usage over a billing cycle. | Predictable monthly usage exhausts the included budget. |
| Requests / second | Burst throughput right now. | Normal traffic spikes begin to receive 429 Too Many Requests responses. |
Choose a plan for your workload
Business is the first public tier with gRPC access. Choose Business or Professional when the architecture depends on transaction streaming, bot-style workloads, stream consumers, or shared production traffic that needs more headroom than standard JSON-RPC usage.
RPC pricing questions
Are there rate limits or quotas?▾
Yes. Free includes 500K credits per month and 10 RPS; Developer includes 10M credits and 50 RPS; Business includes 100M credits and 200 RPS; Professional includes 200M credits and 500 RPS. Credits measure total monthly usage, while RPS measures short-term request capacity. If you see 429 Too Many Requests during normal traffic, review burst behavior and plan headroom before launch.
Which Carbium RPC plan includes gRPC?▾
Business and Professional include gRPC access. If your production architecture depends on transaction streaming, stream consumers, or bot-style workloads, Business is the first public tier to evaluate.
Which plan is right for a standard application backend?▾
Start with Free for testing and proof-of-concept work. Developer is the first public tier intended for an early production backend with standard JSON-RPC usage. Choose based on both monthly credits and the request bursts your application needs to handle.
What is the difference between credits and RPS?▾
Credits are your total monthly usage budget. RPS is the maximum request capacity available at one time. Both limits matter: a workload can stay below its RPS cap but consume its monthly credits over time, or have credits available but hit RPS limits during bursts.
When should I choose Business or Professional?▾
Choose Business when you need gRPC or production headroom for shared team traffic, trading systems, or stream consumers. Choose Professional when higher throughput and multi-service production workloads are normal rather than occasional.
Where can I review technical RPC details?▾
Read the Carbium RPC documentation for endpoint setup, authentication, rate-limit guidance, and integration examples. Pricing decisions should be checked against the current published plan table before launch.
| Plan | Credits / month | Published capacity |
|---|---|---|
| Free | 500K | 10 RPS |
| Developer | 10M | 50 RPS |
| Business | 100M | 200 RPS |
| Professional | 200M | 500 RPS |
