It's a split decision.
YepAPI fits applications that need SEO/SERP, scraping, social and commerce data, and AI model calls behind one usage-billed JSON API. Scrapfly fits scraping and browser workloads that need managed proxies, JavaScript rendering, Chromium, extraction, crawling, or agent workflows, with SDKs and monthly credit tiers. Pick YepAPI for broad data and model endpoints and no monthly minimum; pick Scrapfly when its browser stack and published concurrency tiers match the job. They overlap on scraping, but are not interchangeable across the full feature set.

02Pricing at real usage
YepAPI starts with $5 signup credit, no card required, then charges per call or other metered unit; the pricing page lists Google SERP from $0.01 per call and no monthly fees or minimums. It says failed calls are not charged and lists no rate limits. There is no subscription to amortize at volume, so spend follows endpoint usage; check each endpoint's current price before estimating a workload.
Scrapfly's free tier gives 1,000 signup credits with no card and no time limit. Paid plans start at Discovery, $30/month for 200,000 credits and five concurrent requests. Pro is $100 for one million credits and 20 concurrent requests; Startup is $250 for 2.5 million and 50; Enterprise is $500 for 5.5 million and 100. Overflow is $3.50 per 10,000 credits on Pro, $2 on Startup, and $1.20 on Enterprise. Credit consumption depends on product and workload, so compare a representative request mix before budgeting.
03API, SDKs and integration
YepAPI exposes HTTP endpoints such as POST /v1/seo/keywords/overview, /v1/serp/google, /v1/scrape, and /v1/media/queue. Calls share an API key and return JSON. Its homepage points developers to docs and llms.txt for AI agents, and names Claude Code, Cursor, Codex, an MCP server, and agent skills. The shared key and response format span its SEO, scraping, social, commerce, and model endpoints.
Scrapfly offers separate endpoints for scraping, screenshots, extraction, crawling, and agents, plus a WebSocket CDP URL for managed Chromium. It lists SDKs for Python, TypeScript, Go, and Rust, and full Playwright and Puppeteer compatibility. Integrations include Zapier, Make, n8n, OpenClaw, LlamaIndex, LangChain, CrewAI, and Scrapy. Its agent API names Browser Use, Stagehand, and Vibium compatibility; its homepage also lists an MCP server.
04Open source, self-hosting and lock-in
Both products are presented as hosted services: YepAPI provides metered API endpoints, while Scrapfly runs scraping infrastructure and managed Chromium. Neither vendor publishes an open-source license, a self-hosting option, or details of a data-export path. Ask how request logs, extraction schemas, crawler results, and agent state can be exported before building dependencies around them.
Migration costs depend on the workload. YepAPI combines SEO, scraping, social and e-commerce data, and model calls behind one key and JSON format; replacing it may mean sourcing several APIs. Scrapfly covers scraping and browser workflows, so replacing it means moving proxy, rendering, extraction, crawler, or browser-agent behavior. Keep endpoint wrappers in your codebase and store outputs in systems you control.
Questions people ask
Which is cheaper for a small workload?
It depends on the request mix. YepAPI has $5 in signup credit and charges per call or other metered unit, with no monthly minimum. Scrapfly has 1,000 free signup credits, then its listed paid plans start at $30/month. Compare the credit or call cost for the specific endpoints you need.
Does Scrapfly have a free tier?
Yes. Scrapfly lists 1,000 signup credits with no credit card and no time limit. Its paid Discovery plan costs $30/month and includes 200,000 credits and five concurrent requests. The number of jobs those credits cover depends on the products and operations used.
Do YepAPI and Scrapfly offer SDKs?
Scrapfly lists SDKs for Python, TypeScript, Go, and Rust. YepAPI documents HTTP endpoints with a shared API key and JSON responses, and points to llms.txt, an MCP server, and agent skills. Its homepage does not name language SDKs, so verify current docs if an SDK is a requirement.
Can I self-host either service?
Neither vendor publishes a self-hosting option or open-source license. Both are presented as hosted services, with Scrapfly explicitly providing managed Chromium and scraping infrastructure. If self-hosting or a specific license is a deployment requirement, ask the vendor before adopting the service.
