Service Plans
Ankr provides the top-performing globally-distributed enterprise-grade infrastructure of nodes to empower your Web3 projects with blockchain interaction capabilities.
Our solutions work under the following Service Plans:
- Public — public endpoints for free blockchain interaction provided with Public features and rate limits.
- Premium — private endpoints for high-performing blockchain interaction provided with Premium features and rate limits.
- Freemium — a service plan to try out premium features before going fully Premium. Provides free 200M API credits monthly for API interactions. You have to sign in on the platform without topping up your account balance to access Premium features but under Public rate limits.
- Enterprise — customer-tailored solutions for the most demanding blockchain interaction cases.
Here is the list of solutions we have at your disposal on the Web3 API (opens in a new tab) platform under the Service Plan you've selected:
- Node API — the endpoints that enable your Web3 projects to start interacting with an extensive list of supported blockchains, give access to viewing the usage statistics for the data queried, and provide the means for RPC API methods testing.
- Advanced API — a ready-to-use indexed collection of endpoints that supports simultaneous querying of multiple blockchains (19 mainnet and 7 testnet chains available) for the most popular Web3 scenarios at near-instant speeds; available via JavaScript/ Python SDKs and React Hooks. Advanced API also gives you access to the usage statistics for the data queried.
Here is the list of blockchains supported: Chains Quickstart.
Service Plans Comparison
The Node API and Advanced API solutions come with both Public, Freemium, and Premium service plans but differ significantly by the rate limits and other performance features supported depending on the plan selected.

Charging Models
Our Premium service plan users can choose to query blockchain data under the following charging models:
- Pay-as-you-go — pay for each request you make.
- Deal — monthly subscription with 20% extra credits added on top for any of the Deal options chosen ($500-3,000).
Pay-as-you-go
Pay-as-you-go (PAYG) is a usage-based charging model for the Premium Plan services. PAYG means that you commit to no subscriptions but pay for each request you make. The minimum PAYG deposit to start using the Premium Plan features is 10USD (or equivalent amount in ANKR tokens).
Deal
Deal is a subscription-based charging model for the Premium plan services. It is a recurring 500USD — 3,000USD payment that provides 20% extra API credits compared to the same sum spent on Pay-as-you-go. The API Credits are to be spent within a month to call both Node and Advanced APIs for all the chains we support. Next billing period, the Deal monthly quota refreshes.
Deal in a nutshell:
500USD—3,000USDmonthly API credits with20% extracredits added on top of your payment.- Both Node and Advanced APIs included.
- All chains covered.
PAYG Pricing
The price of our API Credits is pegged to USD. It means that upon using ANKR tokens for PAYG, ANKR calculates into API Credits at the latest ANKR/USD exchange rate.
Our PAYG pricing model: 0.10 USD = 1M API Credits
How We Charge
For both our Premium plan's charging models — Pay-as-you-go (PAYG) and Deal — we charge per method used in request. Various methods have different API credit values per request. A method's API credit value calculates based on a method's usage intensity and multiple factors that include using the computational, memory, storage, and network resources.
We charge no matter whether a request has been successful or not. In other words, a charge is taken for each request coming to our worker, regardless of a node's response.
PAYG/Deal charging summary:
Correct call—Incorrect call—Correct call + incorrect method—Correct call + rate limiting
- Correct call (charged) — a request uses a supported method and has a valid JSON-RPC structure.
- Incorrect call (not charged) — a request has an invalid JSON-RPC structure or a batch request has the same ID in multiple requests. We can't parse such a request.
- Correct call + incorrect method (charged default amount) — a request uses an unsupported method though has a valid JSON-RPC structure. We charge default amount of credits for the infrastructure usage.
- Correct call + rate limiting (not charged): a request uses a supported method and has a valid JSON-RPC structure but receives a
429error due to rate limiting.
