Billing & CU pricing

Access fees, daily CU tiers, and per-product billing for Pipelines, RPC API, and Streams API.

EVMKit pricing has two parts:

choose one or more products to unlock
choose a daily compute unit (CU) tier

Your monthly subtotal is:

monthly price = sum(selected API access fees) + selected daily CU tier fee

Billing can be monthly or quarterly:

monthly billing invoices the monthly subtotal
quarterly billing invoices 3 months up front and applies a 10% discount to that subtotal

Daily included CU is enforced per account per day. Quarterly billing changes invoice cadence, not the daily allowance model.

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

Product access fees

API	Access fee / month	Notes
`Streams API`	`EUR 15`	Required for websocket streams and websocket connection capacity
`Pipelines API`	`EUR 15`	Unlocks managed sources, destinations, routes, delivery logs, and webhook delivery
`RPC API`	`EUR 25`	Unlocks public JSON-RPC and EVMKit RPC methods

You can select any non-empty product combination. Access fees add together.

Daily CU tiers

Daily CU limit	CU tier fee / month
`1M / day`	`EUR 15`
`5M / day`	`EUR 40`
`10M / day`	`EUR 79`
`20M / day`	`EUR 154`

Capability rules

Pricing only controls access and included capacity. Request CU weights stay the same across tiers.

Capability	Included when
Websocket products	the subscription includes `Streams API`; active websocket caps then scale by daily CU tier
Managed pipelines	the subscription includes `Pipelines API`; source, destination, and route capacity then scales by daily CU tier
Priority support	the selected tier is `120M / day` or higher

Worked examples

Selection	Monthly subtotal	Quarterly invoice
`Streams API` + `1M / day`	`EUR 30`	`EUR 81`
`Pipelines API` + `20M / day`	`EUR 169`	`EUR 456.30`
`Streams API` + `RPC API` + `120M / day`	`EUR 904`	`EUR 2,440.80`
`All 3 APIs` + `180M / day`	`EUR 1,333`	`EUR 3,599.10`
`All 3 APIs` + `360M / day`	`EUR 2,533`	`EUR 6,839.10`

Pipelines pricing

The Pipelines product is unlocked by the Pipelines API access fee.

That access covers:

dashboard-based management
X-Api-Key access through Pipelines API
sources, destinations, and routes
overview and delivery-log reads
destination tests and route tests
sources, destinations, and routes, each capped by the selected daily CU tier

Managed pipeline resource capacity scales with the selected daily CU tier. The same cap applies independently to sources, destinations, and routes:

| Daily CU tier | Sources / account | Destinations / account | Routes / account | | --- | ---: | | 1M / day | 5 | 5 | 5 | | 5M / day | 10 | 10 | 10 | | 10M / day | 10 | 10 | 10 | | 20M / day | 30 | 30 | 30 | | 60M / day and above | 50 | 50 | 50 |

Pipelines action	Price
Delivery attempt	`5 CU`

Streams API CU pricing

Stream action	Price
WebSocket connection	`10 CU`
Published state change on a subscribed stream	`1 CU`

Allowance behavior

billed RPC methods and billed Streams API actions require an active subscription and enough remaining allowance for the request reservation
Pipelines access unlocks the managed control plane for sources, destinations, routes, tests, and delivery logs
evmkit_prepare, evmkit_call, and evmkit_trace reserve 1 CU up front and then settle to the gas-based price from the response
short-window RPC rate limiting returns 434; see Rate limits
billed RPC requests return 402 Payment Required when no allowance remains
Streams API connections are rejected or closed when billed state changes cannot be covered
