Billing & CU pricing

Plan comparison and CU pricing for the public Search API, RPC methods, and Streams API state changes.

The public Search API, RPC API, and Streams API are metered in compute units (CUs).

Pricing now has two public tracks: multiselect core APIs with priced combinations, and higher-capacity bundles.

All offerings use the same per-request CU pricing, so moving to a different plan changes included capacity rather than per-request CU weights.

For the shared short-window limiter, see Rate limits.

Core APIs

Selection	Price / month	Included CU / day	CU / `12s` window	Active websocket connections
`Streams API`	`EUR 80`	`12,000,000`	`3,000`	`2`
`RPC API`	`EUR 100`	`16,000,000`	`4,000`	`0`
`Search API`	`EUR 160`	`20,000,000`	`6,000`	`0`

core API selections can be billed monthly or quarterly
quarterly billing applies a 10% discount to the monthly subtotal and is invoiced for 3 months up front
single-API selections and multi-API combinations each have their own allowance, burst limit, and websocket cap

Combination	Price / month	Included CU / day	CU / `12s` window	Active websocket connections
`Streams + RPC`	`EUR 150`	`20,000,000`	`5,000`	`3`
`Streams + Search`	`EUR 190`	`24,000,000`	`7,000`	`3`
`RPC + Search`	`EUR 220`	`26,000,000`	`7,500`	`0`

combinations can be billed monthly or quarterly
quarterly billing applies a 10% discount to the monthly subtotal and is invoiced for 3 months up front
combinations include discounted pricing relative to buying each API separately
allowance, short-window rate limits, and websocket caps are enforced per account and shared across API keys and regions

Bundle	Price / month	Included CU / day	CU / `12s` window	Active websocket connections	Monitoring endpoints
`Professional`	`EUR 1,200`	`180,000,000`	`50,000`	`5`	No
`Advanced`	`EUR 2,000`	`360,000,000`	`100,000`	`10`	Yes

bundles can be billed monthly or quarterly
quarterly billing applies a 10% discount to the monthly subtotal and is invoiced for 3 months up front
monitoring access includes GET /v1/monitoring/positions and GET /v1/monitoring/unhealthy/ws
allowance, short-window rate limits, and websocket caps are enforced per account and shared across API keys and regions

billed RPC methods, billed Search API requests, billed monitoring requests, and billed Streams API actions require an active subscription and enough remaining allowance for the request reservation
evmkit_prepare, evmkit_prepareRaw, evmkit_call, and evmkit_trace reserve 1 CU up front and then settle to the gas-based price from the response
POST /v1/size is capped to 18 iterations per item
POST /v1/size settles to the per-item 1 CU base plus gas-priced simulations
profile=fast, balanced, and deep reserve the per-item base plus the max gas-priced simulation cost for 6, 10, and 18 capped iterations
monitoring endpoints are available only on the Advanced plan
short-window RPC rate limiting returns 434; see Rate limits
billed RPC requests return 402 Payment Required when no allowance remains
billed Search API sizing requests return 402 Payment Required when no allowance remains
billed monitoring requests return 402 Payment Required when no allowance remains or the plan is below Advanced
Streams API connections are rejected or closed when billed state changes cannot be covered
