Flat monthly price. Every limit is a ceiling the gateway enforces.
Iteradian has 4 plans, billed monthly or annually in USD. Free RPC is free, with 25 requests per second, 3,000,000 requests per month included. Developer RPC costs $39 per month with 250 requests per second, 25,000,000 requests per month included. Professional RPC costs $169 per month with 500 requests per second, 80,000,000 requests per month included. Dedicated RPC is priced per contract, with requests per second and concurrency set in the contract, unlimited monthly requests, organization-reserved nodes. Every limit is enforced by the gateway, not estimated.
New organizations start with a 7-day free trial. Prices and limits read from the control plane on 27 October 2026.
One monthly price. Every limit is enforced, not a forecast.
Each limit below is applied on live traffic before a node is touched. Past the included allowance, metered overage runs up to a fixed cap; past a ceiling you get an HTTP 429 with a JSON-RPC error body, never a silent drop.

What happens when you cross a limit.
Three limits are checked before your request reaches a node: your organization's requests per second, its concurrent requests, and the monthly allowance with its overage cap.
Breaching any of them returns HTTP 429 with a JSON-RPC 2.0 error body, never a silent drop. Throttled requests are recorded in your usage and request log, so a rejection is something you can see rather than something you have to infer.
01What happens when I use up the monthly request allowance?
While overage is enabled on the plan, requests keep flowing and are metered past the allowance: Free RPC includes 3,000,000 requests; Developer RPC includes 25,000,000 requests — overage $0.005 per 1,000 requests, capped at $150 per billing period; Professional RPC includes 80,000,000 requests — overage $0.003 per 1,000 requests, capped at $350 per billing period. Once the overage cap is reached, requests are rejected with HTTP 429 and JSON-RPC error code -32007 until the period resets. On a plan without overage, the allowance itself is the ceiling and the error code is -32006.
02What happens if I go over the rate limit?
The request is rejected with HTTP 429 and a JSON-RPC error body carrying code -32005. The error data carries the allowed rate and a retryAfter value. The counter is a one-second sliding window per organization, shared across gateway instances, so the ceiling is the same whichever instance takes the request. A batch of N calls counts as N requests.
03What counts as a concurrent request?
Any request your organization has in flight at the gateway. A slot is reserved before the request is forwarded to a node and handed back when it completes. Over the plan ceiling you get HTTP 429 (code -32005) rather than a queue, so a runaway client fails fast instead of backing up behind itself.
04Is there a free trial?
Yes. New organizations start on the Developer RPC plan in trialing status for 7 days and can issue API keys immediately. Free RPC is also available at no cost, with no time limit.
05How do I change plan?
Self-serve plans change from Billing in the dashboard, and your organization follows the payment provider (Stripe or Paddle), so the plan you run on and the plan you are billed for cannot drift apart. Dedicated plans are provisioned by our team — contact sales.
06How does annual billing work?
You pay for twelve months at once, at the annual price. Your request allowance is still monthly: it resets at the start of each month of your billing year. Overage for a month is billed at the end of that month, up to the plan's monthly overage cap. The year renews automatically until you cancel.
07Can I switch from monthly to annual?
Yes, at any time, from Billing in the dashboard. Your billing year starts that day, and you pay the annual price less a credit for the unused part of the current month.
08Can I switch from annual to monthly?
At the end of your billing year. Cancel, then choose monthly billing when the year ends, or contact support.
09Can I get a refund on an annual plan?
Your first paid purchase can be refunded in full within 14 days if you have used less than 10% of the first month's included requests. That applies to monthly and annual plans alike. Otherwise, cancelling stops the renewal but does not refund the remaining months.
