RPC Rate Limit Usage Tracker

WHAT IT DOES RPC Rate Limit Usage Tracker is a read-only developer tool that simulates RPC rate limit tracking and provides usage visualizations for EVM endpoint planning. It detects the provider type from the URL (Alchemy, Infura, QuickNode, Ankr, or Generic), applies known rate limits for each provider, simulates request consumption across a configurable number of test calls, and displays usage metrics including remaining requests, usage percentage, and rate limit status. The tool generates a visual dashboard with a speedometer-style gauge, usage progress bar, detailed request-by-request breakdown, Prometheus-style metrics output, and actionable recommendations for staying within rate limits—helping developers plan capacity, avoid API throttling, and optimize request patterns. HOW TO USE Connect your EVM-compatible wallet via the BGWallet bridge and select the network you are targeting. Enter your RPC endpoint URL and the number of test requests to simulate (1-20). Click "Track Rate Limit Usage" to generate a comprehensive rate limit usage report. Results include provider detection, rate limit per reset window, usage percentage with visual bar, remaining request count, request-by-request breakdown table, simulated rate limit headers, Prometheus-style metrics, and tailored recommendations. The tool provides color-coded status indicators (green for healthy, yellow for approaching limit, red for exceeded) to quickly assess usage. All analysis is read-only—no signatures or transactions are submitted. TECHNICAL MECHANISM The tool performs URL-based provider detection by scanning for provider-specific keywords (alchemy, infura, quiknode, ankr). It applies a built-in rate limit database with known limits: Alchemy (300 req/min), Infura (100 req/min), QuickNode (500 req/min), Ankr (100 req/min), and Generic (100 req/min). For each simulated request, the tool calculates remaining capacity as limit - (request_number + random_variance). The random variance (0-5 requests) simulates real-world variability. The tool flags rate limit exceeded when used requests exceed the provider's limit. Usage percentage is calculated as (used_requests / total_limit * 100). The tool generates simulated rate limit headers (X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset) for reference. Results are displayed in a structured dashboard with color-coded severity levels: green (80%). The tool also outputs Prometheus-style gauge metrics (rpc_rate_limit_remaining, rpc_rate_limit_used, rpc_rate_limit_percent) suitable for integration with monitoring systems. WHAT IT CANNOT SEE This tool has fundamental limitations that users must understand. It cannot track rate limit usage for providers that do not expose rate limit headers—some providers do not include rate limit information in their responses. It cannot measure actual request throughput or concurrency—the tool simulates usage but cannot measure real-time request rates. It cannot predict when rate limits will reset without provider-specific timing logic—reset timing varies by provider and plan. It cannot automatically adjust request patterns to avoid rate limits—the tool provides recommendations but does not implement backoff or throttling. It cannot track usage across multiple API keys or accounts—the tool only simulates a single endpoint. It cannot detect rate limiting that occurs at the network layer rather than the application layer—some rate limits are enforced by load balancers or CDNs. It cannot monitor rate limit usage over extended periods—the tool provides a point-in-time simulation. It cannot detect usage spikes or burst patterns. The tool's rate limit values are based on publicly available information and may not reflect the user's specific plan or API key tier. PLEASE NOTE This tool only supports EVM-compatible blockchains (Ethereum, Polygon, BSC, Avalanche C-Chain, Optimism, Arbitrum, and their testnets). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. The tool is free, open-source, requires no API keys, and uses the wallet's native provider for all read operations. Rate limit values are estimates—always check your provider's official documentation for accurate limits.
