It's a split decision.
YepAPI is a usage-billed API for SEO, scraping, social and e-commerce data, and AI models. Moz API focuses on SEO data, including keyword and link metrics, with monthly row plans and a free tier. Choose YepAPI if one API key and per-call billing fit a varied workload. Choose Moz if your application needs Moz’s SEO metrics and a predictable monthly row allowance. Compare endpoint coverage and row usage before moving an existing integration.

02Pricing at real usage
YepAPI charges by call or other metered usage, with no subscription or monthly minimum. Its pricing lists Google SERP calls from $0.01; signup includes $5 in credit, and failed calls are not charged. There is no free plan, and the vendor says it does not impose rate limits. Costs rise with endpoint use, so estimate spend from the calls your application makes.
Moz API’s free plan includes 50 rows per month and one request every 10 seconds. Paid plans start at $20 per month for 3,000 rows, with no overages on Starter Medium. Starter Large is $75 for 15,000 rows, with overages at $5 per 1,000 rows. Growth plans range from $125 for 50,000 rows to $500 for 500,000 rows; their listed overage rates range from $25 to $10 per 10,000 rows. Moz bills by monthly rows, not per call.
03API, SDKs and integration
YepAPI exposes POST endpoints that return JSON, using one API key across SEO, scraping, social and e-commerce data, and AI models. The homepage shows calls such as /v1/seo/keywords/overview and /v1/scrape. It links to API docs and an llms.txt file, and names Claude Code, Cursor, Codex, an MCP server and agent skills as integration paths. The vendor does not publish SDK or language details on its homepage, so check the endpoint docs before choosing a client library.
Moz API provides SEO data for custom tools, dashboards and integrations. Its published integration details include JSON-RPC 2.0, API-token authentication and MCP connections to supported AI clients and coding agents. The listed data includes keyword metrics, search intent, related keywords, ranking keywords and link metrics such as Domain Authority and Spam Score. Neither product’s homepage names a CLI. Plan around the API protocol and the fields your application consumes rather than assuming SDK parity.
04Open source, self-hosting and lock-in
Neither vendor publishes open-source licensing terms, self-hosting options or a data-export path for these APIs. Treat both as external services in your architecture: your application depends on their availability, authentication and response schemas.
YepAPI’s shared key and consistent JSON format can reduce the number of separate integrations in a stack, but it also concentrates several data types behind one provider. Moz API centers on Moz SEO metrics and row-based plans. Moving between them is not just a billing change: map each provider’s available fields and endpoint behavior, then update the code that consumes those responses. Ask each vendor about export rights, retention and migration support before making either API a dependency for stored or customer-facing data.
Questions people ask
Is YepAPI cheaper than Moz API?
It depends on workload. YepAPI has no monthly minimum and lists Google SERP calls from $0.01, plus $5 in signup credit. Moz starts with a free 50-row plan, then charges $20 per month for 3,000 rows. Compare your expected calls and row counts against the endpoints you need.
Does Moz API have a free tier?
Yes. Moz lists a free plan with 50 rows per month and one request every 10 seconds. It is a limited allowance for trying the API, not an unrestricted production tier. Paid plans begin at $20 per month for 3,000 rows.
Can YepAPI replace Moz API?
Possibly, if the YepAPI endpoints your application needs cover its SEO data requirements. YepAPI lists keyword, backlink, domain and Google results data; Moz lists metrics including Domain Authority, Page Authority and Spam Score. Check field-level coverage and response formats before changing an integration.
Can I self-host either API?
Neither vendor publishes self-hosting options for these APIs. The listed integration models are API access, with MCP connections also described for both products. If self-hosting or a specific data-export path is a requirement, ask the vendor before building around its service.
