02Pricing at real usage
YepAPI charges by API call or other metered usage, with no subscription or monthly minimum. It starts at $0.01 per call; the pricing page lists Google SERP and web scraping at $0.01, and keyword overview at $0.03. The $5 signup credit gives you initial usage, and failed calls are not charged. AI model costs vary by model: the homepage lists Z-Image Turbo from $0.03 per image and Kling 3.0 Turbo from $0.192 per second. NanoGPT offers a pay-as-you-go option with a free web-only model; paid model use comes from your balance at list prices. Pro costs $12 per month and includes specified open-source model usage. Manually pinning a provider adds 5%; bring-your-own-key requests cost 5% of normal model cost. Your total on either service depends on usage.
03API, SDKs and integration
YepAPI exposes endpoints for SEO, Google SERP results, scraping, social and commerce data, and AI media generation. Requests use a shared API key and return JSON; scraping can return markdown, HTML or screenshots. The docs show HTTP POST endpoints such as /v1/seo/keywords/overview and /v1/scrape. The homepage points developers to API docs and llms.txt, and names an MCP server, agent skills, Claude Code, Cursor and Codex. NanoGPT offers an OpenAI-compatible API for model access and links to API documentation. Its homepage also names Claude Code, Cursor and Cline. Neither vendor lists SDKs or programming languages in the named integration details, so confirm language-specific support and endpoint behavior in the docs before adopting either. NanoGPT's compatibility claim gives teams a familiar API shape, but does not establish identical behavior across models.
04Open source, self-hosting and lock-in
Neither vendor publishes an open-source licence or self-hosting option. Both are presented as services accessed through a web interface or API, so teams should confirm deployment and data-handling requirements with the vendors before sending sensitive workloads. YepAPI's shared key and consistent JSON response format can simplify calls across its endpoints, but applications still depend on its endpoint names, schemas and metered service. NanoGPT's OpenAI-compatible API may ease integration with code written for that interface; model-specific behavior can still require changes. NanoGPT says chat history stays on the user's device. Neither vendor publishes a data-export format or migration procedure. Treat portability as an application concern: keep provider calls behind an internal interface, and retain any records your application needs outside the service.
Questions people ask
Can YepAPI handle both data APIs and AI model calls?
Yes. YepAPI offers SEO and SERP data, scraping, social and commerce data, plus a catalog of 285 AI models for chat, image, video and voice. Its homepage describes using the same API key across endpoints and models, with JSON responses.
Which service has the lower starting cost?
YepAPI lists API calls from $0.01 and includes $5 in signup credit, with no subscription or monthly minimum. NanoGPT has a free first chat and one free web-only model; its Pro plan costs $12 per month. Paid model costs depend on usage.
Does NanoGPT use the OpenAI API format?
NanoGPT describes its developer API as OpenAI-compatible. Its homepage does not specify full endpoint-by-endpoint compatibility or identical behavior across models. Check its API documentation against your client's required endpoints before switching a production integration.
Do either service's rate limits make it unsuitable for production?
YepAPI says it has no rate limits. NanoGPT describes its rate limits as generous but does not give a numeric limit in its pricing details. Check NanoGPT's current API documentation and confirm expected throughput with the vendor for production workloads.
