A bill you can compute in advance.

Fixed monthly plans priced in request units (RUs). Each RPC method is weighted by its real server cost and those weights are published up front. Standard reads cost 3 RUs, eth_getLogs costs 4 RUs, writes cost 5 RUs, heavy methods like debug_* cost 6 RUs. You pick a plan by your monthly RU volume, starting at $49/mo for 30M RUs. No compute-unit multipliers, no hidden tiers, no surprise overage at 2 a.m. Or skip the plan: on-demand usage is $25 per 15M request units with no monthly fee, up to a spending limit you set.

A request unit is the measure of one RPC call’s server cost. Because eth_blockNumber and debug_traceTransaction are wildly different workloads, a flat "one call = one request" model would either overcharge the cheap calls or undercharge the expensive ones. RUs make the billing honest: cheap methods stay cheap, expensive ones cost a little more. Every weight is published so you can calculate your monthly spend before you ship.

No rate limit on monthly plans. The free trial and on-demand usage without a plan are limited to 100 requests per second (burst 200). On a monthly plan you pay for monthly request units, not for artificial burst caps: if your traffic spikes, requests still go through at full speed until you reach your monthly RU allocation. Every method’s RU weight is published up front.

You decide. By default nothing is billed beyond your plan. If you enable on-demand usage, extra capacity is added in fixed blocks of 15M RUs at $25 per block, and only up to a monthly spending limit you set yourself. You get email alerts at 80, 90 and 100 percent of your included units, so the bill is never a surprise. Your spending limit pays for whole blocks ($50 covers 30M request units); you get alerts at 80, 90 and 100% of it, and once it is used up, requests get HTTP 429 until you raise it. If you are consistently overshooting, that is usually a signal to move up a tier, and switching is prorated.

Archive depth and trace_* / debug_* support are properties of each chain’s node pool, not of your plan: the Networks page shows per chain whether the pool holds full or partial archive state and which debug and trace methods its nodes answer, and every plan gets what the chain offers at the published weights (6 RU for traces). The only plan-gated calls are the three unbounded state-iteration methods, debug_accountRange, debug_storageRangeAt and debug_dumpBlock, which are enabled per account on request from Business upward.

Native gRPC (Sui sui.rpc.v2 in Beta, Tron protocol.Wallet) is included on every plan at the same endpoint. A unary gRPC call costs exactly the request units of the matching JSON-RPC or HTTP method, so there is no gRPC surcharge. A Sui BatchGetTransactions or BatchGetObjects call bills once, whatever the item count. Sui server streams (Subscribe*, List*) bill by delivered data at 1 RU per 24 KB, rounded up once when the stream closes; opening a stream is free and you get five concurrent streams per key. Pick any sui_grpc_ or tron_grpc_ method in the calculator above to see the weight.

Yes. Upgrade or downgrade any time from the dashboard. Changes take effect immediately, billing is prorated. Annual plans are 17% cheaper than monthly, with the same no-lock-in switching.

Yes. 5M request units over 14 days at 100 requests per second (burst 200), no credit card required. You get a live API key within seconds and access to every chain. When the trial ends, add a card to keep the same key on on-demand usage, or choose a plan. If you do neither, the key deactivates and nothing is charged.

Yes. Add a card in the dashboard and pay $25 per 15M request units, with no monthly fee, up to a spending limit you set (new accounts start at $50, and until your first paid invoice the limit can be at most $100, which covers 60M request units). On-demand usage without a plan is limited to 100 requests per second; a monthly plan removes that limit.

Credit card and crypto on every monthly plan. On-demand usage without a plan is card only. Enterprise customers can arrange invoicing, wire transfers and custom billing terms.

Yes. The annual billing cycle gets you 17% off any self-serve tier, Enterprise included. Need more than the 1B request units on Enterprise? The Custom tier is a contact-sales plan: we scope a volume and a rate for your workload, with discounts that compound as the commitment grows.

Two structural differences. First, BoltRPC’s blockchain RPC pricing uses published, fixed RU weights per method (for example eth_getLogs = 4 RU, eth_call = 3 RU, eth_sendRawTransaction = 5 RU), so you can estimate your bill before you ship. Second, monthly plans carry no rate limit, so bursts during liquidations or token launches route at full speed until you hit your monthly allocation. That means predictable monthly bills and no surprise throttling at the worst moment.
