It's a split decision.
Choose YepAPI when your application needs metered access to SEO, scraping, social, commerce or AI endpoints through one JSON API key. Choose Serpstat when a team needs a broader SEO workspace for keyword and competitor research, site audits and rank tracking, with API access as part of that stack. YepAPI bills by call and lists no rate limits; Serpstat uses monthly plans with daily search and other plan quotas. Neither homepage names language-specific SDKs.

02Pricing at real usage
YepAPI has no monthly plan or minimum, and its pricing page lists a $5 signup credit with no card required. Google SERP calls start at $0.01; other endpoints have their own listed prices, so the bill grows with calls and the endpoint mix. Failed calls are not charged, and YepAPI says there are no rate limits.
Serpstat offers a seven-day trial, then plan-based billing. The Individual plan is $69 month to month or $50 per month with annual billing. Team is $129 or $100; Team x2 is $209 or $169; Agency is $499 or $410. These plans bundle quotas, including searches, audits and exports, so higher usage can require a higher tier. Enterprise pricing is custom. Extra AI Visibility checks cost $20 per 1,000, with a $40 minimum top-up.
03API, SDKs and integration
YepAPI presents a shared API key for its SEO, SERP, scraping, social, commerce and AI endpoints. The homepage shows POST requests and JSON responses, including endpoints such as /v1/seo/keywords/overview, /v1/serp/google and /v1/scrape. It directs developers to API docs and an llms.txt file, and names Claude Code, Cursor, Codex, an MCP server and agent skills. The homepage does not name language-specific SDKs or a CLI.
Serpstat combines its SEO workspace with API and data solutions. Its homepage describes keyword, competitor, audit and rank-tracking tools, and calls its API documentation transparent. It names Google and Bing and says keyword data covers Google in 230 countries. The homepage does not name language SDKs or a CLI. That leaves implementation details such as SDK support and API-specific quotas to confirm in the documentation or with the vendor.
04Open source, self-hosting and lock-in
Neither vendor's homepage states an open-source license or a self-hosting option. YepAPI is presented as an API service; Serpstat as a web platform with API and data solutions. Plan for vendor-hosted access rather than assuming either can run inside your infrastructure.
Both products expose vendor-specific services, so replacing them means mapping calls or workflows to another provider. YepAPI uses a shared key and JSON responses across endpoints, but its homepage does not describe a data export path. Serpstat includes export-row allowances in its plans and says teams can migrate projects from other services at no cost. Its homepage does not specify export formats or whether project migration moves historical data. Confirm export formats, retention and migration scope before storing critical workflows or data in either service.
