It's a split decision.
Choose YepAPI for one API key across SEO, scraping, social and e-commerce data, plus AI models, with $5 in signup credit and no monthly minimum. Choose DataForSEO for a set of specialized SEO and marketing APIs, including SERP, keyword, backlink and on-page data, with SERP pricing starting at $0.0006. Both bill by usage. The practical choice is a broad, unified API versus a more focused data stack.

02Pricing at real usage
YepAPI gives new accounts $5 in signup credit, requires no card, and has no subscriptions or monthly minimums. The pricing page lists Google SERP at $0.01 per call for 10 results, web scraping at $0.01 per call, and keyword overview from $0.03 per call. It also lists Z-Image Turbo at $0.03 per image and Kling 3.0 Turbo from $0.192 per second. Failed calls are not charged.
DataForSEO offers $1 in trial credit, then requires a $50 minimum account top-up; unused balance does not expire. Its SERP API starts at $0.0006 per SERP. DataForSEO Labs lists $0.012 per task plus $0.00012 per item, while Keywords Data starts at $0.0012 per task and On-Page starts at $0.00015 per page. Costs grow by calls, tasks, items or pages, depending on the endpoint. Compare equivalent result types before estimating spend.
03API, SDKs and integration
YepAPI presents a shared API key and consistent JSON responses across its SEO, SERP, scraping, social, commerce and AI endpoints. The homepage shows POST requests such as /v1/seo/keywords/overview, /v1/serp/google and /v1/scrape; scraping can return markdown, HTML or screenshots. Its docs include an llms.txt intended for AI agents. The homepage names Claude Code, Cursor, Codex, an MCP server and agent skills.
DataForSEO organizes functionality into APIs for SERP, AI Optimization, Labs, Keywords Data, On-Page, Merchant, App Data, Business Data, Domain Analytics and Reviews. Its homepage points developers to API documentation, and its pricing page lists templates and integrations for n8n, Postman and Google Sheets, plus MCP access. Neither vendor specifies language coverage for SDKs in the published product details. The integration choice is therefore less about a named language SDK and more about whether one unified key or separate API products better match your codebase.
04Open source, self-hosting and lock-in
Neither vendor publishes an open-source licence, self-hosting option or data-export guarantee. Both are presented as web API services, so your application depends on vendor endpoints rather than a server you operate.
YepAPI's shared key and consistent JSON format can reduce the number of integration patterns in an app, but its SEO, scraping, social and AI features also create a broad dependency on one API. DataForSEO splits its data into specialized API products, which can keep SEO-related integrations distinct but means handling those product endpoints in your code. In either case, switching providers would require mapping endpoint coverage, replacing requests and adapting response handling; the effort depends on how much vendor-specific data and behavior your application relies on. Ask each vendor about export formats and transition support before making either service a long-term data dependency.
Questions people ask
Which API is cheaper for Google SERP data?
DataForSEO lists its SERP API from $0.0006 per SERP. YepAPI lists Google SERP at $0.01 per call for 10 results. Those units and result counts are not identical, so compare the output and volume your app needs rather than treating the entry prices as direct equivalents.
Does YepAPI or DataForSEO have a monthly subscription?
Neither product lists a subscription. YepAPI bills by call or other metered unit, with no monthly minimums. DataForSEO also uses pay-per-use pricing, but its pricing details specify a $50 minimum account top-up; its unused balance does not expire.
Can I self-host either service?
Both products are presented as web-based API services, and neither vendor publishes a self-hosting option. If your architecture requires running the data service inside your own environment, ask the vendors about deployment options before building around their endpoints.
Which service fits an AI agent integration?
YepAPI names Claude Code, Cursor, Codex, MCP and agent skills, and its docs provide an llms.txt for agents. DataForSEO lists MCP access along with n8n, Postman and Google Sheets integrations. Choose based on the endpoints your agent needs, not just the integration list.
