Alchemy RPC pricing, free tier and rate limits
Last updated:
Free tier
Free plan: 30M compute units a month, 300 CU/s (15 requests/s by Alchemy's own conversion), hard cap. (source, read )
Supported chains
Alchemy lists All mainnets and testnets on its chain list (no total stated). (source, read )
Of Triport's networks, it lists Solana, Ethereum, Polygon, BNB Smart Chain, Base, Tron, Robinhood Chain, Stellar; not found on its chain page: TON.
Triport's endpoint, plans and limits on the same networks: Solana RPC endpoint · Ethereum RPC endpoint · Polygon RPC endpoint · BNB Smart Chain RPC endpoint · Base RPC endpoint · Tron RPC endpoint · Robinhood Chain RPC endpoint · Stellar RPC endpoint.

Plans
| Plan | Price / mo | Documented limit | Included / month | Overage |
|---|---|---|---|---|
| Free | Free | 300 CU/s | 30M compute units | — |
| Pay As You Go | See source | 10000 CU/s | — | $0.525 per 1M compute units |
- Free: CU-based - the limit is 300 CU/s (CUPS), NOT literal req/s; Alchemy equates it to 15 requests/s. Method weights vary (Alchemy's own average estimate is 27 CU per request). Hard cap, no overage on Free.
- Pay As You Go: Usage price starts at $0.525 per 1M CU. Throughput is 10000 CU/s, not literal requests/s (Alchemy: starting from 300 requests/s); each additional 5,000 CU/s costs $160/month above 10,000 CU/s, and self-serve capacity ends at 30,000 CU/s. Solana gRPC is separately billed from $75/TB; method weights affect actual throughput.
How Alchemy counts usage
Compute units (CU) at $0.525 per 1M on Pay As You Go; Alchemy's average estimate is 27 CU per request, and method weights vary. Alchemy's own average estimate of 27 compute units per request; real method weights vary. (source, read )
Cost of 1M calls = units per call × Alchemy's published price per unit. Unit prices come from the Plans table above:
- Pay As You Go: $0.525 per 1M CU.
| Call | Units per call | $ per 1M calls inside a plan | $ per 1M calls at Pay As You Go rate ($0.525 per 1M CU) |
|---|---|---|---|
| eth_call (EVM) | 26 CU | — | 26 × $0.525 = $13.65 |
| Average request (Alchemy's own estimate) | 27 CU | — | 27 × $0.525 = $14.18 |
| eth_blockNumber (EVM) | 10 CU | — | 10 × $0.525 = $5.25 |
| eth_getBalance (EVM) | 20 CU | — | 20 × $0.525 = $10.50 |
| eth_sendRawTransaction (EVM) | 40 CU | — | 40 × $0.525 = $21 |
| eth_getLogs (EVM) | 60 CU | — | 60 × $0.525 = $31.50 |
| getAccountInfo (Solana) | 10 CU | — | 10 × $0.525 = $5.25 |
| getBlock (Solana) | 40 CU | — | 40 × $0.525 = $21 |
| getAssetsByOwner (Solana DAS) | 480 CU | — | 480 × $0.525 = $252 |
Units per call from Alchemy's own method price list (source, read ). List prices; bandwidth, add-ons and taxes excluded.
- eth_getLogs is 60 CU on the Compute Unit Costs table and 75 CU in the worked example on the compute-units overview page; the table uses 60.
Where Alchemy's own pages disagree
- eth_getLogs: 60 CU on the Compute Unit Costs table, 75 CU in the worked example on the compute-units overview page (2026-10-13). (source 1, source 2, read )
Streams and how they are billed
Solana gRPC costs $75/TB prorated by bytes; concurrent-stream allowance is not published. (source, read )
