The Free plan gives you an API key with access to selected networks and limited request volume 5 requests per second. It’s ideal for quick prototyping, testing, and early integration before upgrading to paid plans. ## How does the pay-as-you-go model work? You only pay for actual usage beyond the free tier. Billing occurs monthly or when you reach your preset usage cap. You can track consumption and cost estimates in your project dashboard in real time. ## Which blockchains are supported, and can I request new ones? We currently support 70+ networks — including EVM chains, L2 solutions, Non-EVM chains, and testnets like Ethereum, BNB Chain, Polygon, Solana, Tron, TON, Bitcoin, and more. Enterprise customers can request priority onboarding for new chains. ## How long does integration take? Usually under 5 minutes. Sign up → choose networks → get API key → start sending requests. Our SDK and cURL examples help you deploy instantly. ## What’s the difference between the RPC Gateway and Unified API? The RPC Gateway exposes native JSON-RPC interfaces for each network, while Unified API returns normalized data structures (blocks, transactions, tokens) in a single schema across all chains — ideal for multi-chain analytics and indexing. ## Does the API support analytics or machine-learning pipelines? Yes. The Unified API endpoints return indexed, normalized JSON data that integrates seamlessly with ClickHouse, BigQuery, and Python ML frameworks. Perfect for on-chain risk scoring or Web3 data science projects. ## What uptime or SLA can I expect? Our globally distributed infrastructure ensures 99.9%+ uptime. Multiple regions, automatic failover, and active monitoring keep your dApps and services online 24/7. ## Which API protocols do you support (RPC, REST, WebSocket, etc.)? We provide standard JSON-RPC (HTTP & WSS), REST endpoints, and WebSocket event streams. Unified API features include caching, indexing, historical block data, and analytics-ready datasets. ## Can I manage or restrict my API keys? Yes — you can create, revoke, and scope API keys from your dashboard. Restrict access by domain and IP to prevent unauthorized usage. ## Can I scale to millions of users or run a dedicated node cluster? Yes — the Enterprise tier supports dedicated infrastructure, custom SLAs, and private endpoints with on-demand capacity. Perfect for exchanges, wallets, or analytics platforms handling high TPS traffic. ## Can I subscribe to real-time events (logs, transactions, tokens)? Yes. Our EventStream service lets you subscribe to address activity, new blocks, transfers, or contract events via WebSocket or Webhook. You can filter by address, topic, and block range. ## What’s the average latency between block production and API availability? Depending on the network, data is available within 100–400 ms after block finalization. For fast chains like Solana and TON, we stream updates in near real time. #### Create blockchain magic with less effort [Get started for free](https://auth.crypto-chief.com/registration)
