How Chainstack counts usage
Request units (RU): 1 RU per full-node request, 2 RU per archive-node request, the same on every chain. 1 request unit per full-node request, 2 per archive-node request: the spread is the node type, not the method. (source, read )
Cost of 1M calls = units per call × Chainstack's published price per unit. Unit prices come from the Plans table above:
- Growth: $49 ÷ 20M RU = $2.45 per 1M RU, if the whole allowance is used.
- Growth: $15 per 1M RU above the allowance.
| Call | Units per call | $ per 1M calls inside Growth ($49 ÷ 20M RU) | $ per 1M calls at Growth rate ($15 per 1M RU) |
|---|---|---|---|
| Full-node request (any method, any chain) | 1 RU | 1 × $2.45 = $2.45 | 1 × $15 = $15 |
| Archive-node request (any method, any chain) | 2 RU | 2 × $2.45 = $4.90 | 2 × $15 = $30 |
Units per call from Chainstack's own method price list (source, read ). List prices; bandwidth, add-ons and taxes excluded.
