How does FlyCrawl empower Machine Learning (ML) and AI training workflows?

FlyCrawl provides high-throughput web scraping to construct noise-free, deduplicated, and token-optimized pretraining and fine-tuning datasets for Machine Learning (ML), open-weight LLMs, and domain-specific AI models.

Can FlyCrawl automate RAG pipelines and vector embeddings generation?

Yes! FlyCrawl automatically scrapes live web content, cleans HTML to Fit-Markdown, chunks text semantically, and generates native 1536-dimensional and 3072-dimensional vector embeddings ready for direct upsert into Pinecone, Qdrant, ChromaDB, and Milvus without requiring external API keys.

What makes FlyCrawl the ideal Web Scraping SaaS for modern developers?

FlyCrawl is a cloud-native scraping platform delivering 342ms static median latency, worker process recycling with bounded memory, resilient proxy handling, flexible developer billing, and native Model Context Protocol (MCP) server support.

What payment methods does FlyCrawl support?

FlyCrawl supports flexible developer billing including multi-currency digital assets (USDT, TON, TRX, BTC, ETH) and enterprise invoices, featuring automated instant credit top-ups without unnecessary verification hurdles.

Why is FlyCrawl a compelling alternative to Firecrawl?

FlyCrawl is engineered with a compiled Go and .NET core delivering fast extraction (342ms static p50), compatible API endpoints (/v1/scrape, /v1/crawl), native 1536/3072-dim embeddings, and transparent pay-as-you-go pricing without lock-in.

Can I connect FlyCrawl to Cursor IDE, Windsurf, or Claude Desktop?

Yes! FlyCrawl hosts a native Model Context Protocol (MCP) server at https://api.flycrawl.net/v1/mcp enabling AI coding agents to crawl, search, and ingest web knowledge seamlessly.

What is Fit-Markdown and how does it save LLM prompt tokens?

Fit-Markdown uses heuristic DOM pruning to strip cookie modals, sidebars, tracking scripts, and headers while preserving semantic markdown tables, headings, and text, slashing context token usage by up to 95%.

Frequently Asked Questions

Do you charge for failed or blocked scrapes? +

Never. FlyCrawl operates on a strict 100% Free on Failure Guarantee. If a target site cannot be reached, times out, or returns a 5xx error, zero credits are deducted from your balance.

Can I pay using USDT or TON without a foreign credit card? +

Yes! FlyCrawl is built with sovereign Web3 payment rails. You can top up your account with USDT (TRC-20), TON, TRX, BTC, and ETH instantly with zero KYC requirements.

How does Fit-Markdown reduce LLM prompt costs by 95%? +

Traditional HTML contains tens of thousands of tokens of script tags, cookie banners, navbars, and SVGs. Our DOM heuristic engine strips all non-content noise and delivers clean, structured markdown headings, tables, and paragraphs, drastically reducing context tokens.
