Most buyers should pick YepAPI.
YepAPI is a single usage-billed API for SEO, SERP, scraping, social and e-commerce data, plus 285 AI models. Perplexity’s API suite is a better fit when your application needs web-grounded answers with citations, ranked search results, embeddings or typed decisions. YepAPI publishes per-call examples and gives new accounts $5 in credit. Perplexity’s Agent API model rates are token-based, but its pricing page does not list Sonar-specific plans. Choose based on the API output your product needs and how clearly you need to forecast costs.

02Pricing at real usage
YepAPI uses prepaid, usage-based billing, with no subscription or monthly minimum. New accounts get $5 in signup credit, and the homepage says no card is required. The pricing page lists Google SERP calls from $0.01; the homepage also lists web scraping at $0.01 per call and keyword overview from $0.03. Image generation is listed at $0.03 per image, while Kling 3.0 Turbo video starts at $0.192 per second. Failed calls are not charged, and YepAPI says it has no rate limits. Your bill grows with calls and metered units, so estimate it against the specific endpoints and models you use.
Perplexity’s pricing page does not list a Sonar-specific plan or billing schedule. It says Agent API model rates vary and are token-based; the Search API is billed per request. With no published rate in these details, ask Perplexity for current model pricing before estimating production spend.
03API, SDKs and integration
YepAPI exposes endpoints for SEO and SERP data, scraping, social and e-commerce data, and AI models. Its homepage shows POST requests and JSON responses, and says one API key works across endpoints with a consistent JSON response format. The docs are linked from the homepage, which also points to an llms.txt file for AI agents. YepAPI names Claude Code, Cursor and Codex, plus an MCP server and agent skills. The homepage does not name programming-language SDKs.
Perplexity documents several APIs rather than a single Sonar endpoint: Agent returns web-grounded answers with citations, Search returns ranked results and extracted page text, Embeddings supports semantic search and RAG, and Decisions returns typed answers with probabilities. Orchestrator provides OpenAI-compatible access to open-weight models hosted by Perplexity. The docs include quickstarts, a Perplexity SDK and a Perplexity CLI, but the listed pages do not specify SDK languages. The docs also include rate-limit and usage-tier pages.
04Open source, self-hosting and lock-in
Neither vendor publishes an open-source licence or self-hosting option in the product details. Both are presented as API services, so plan for a network dependency rather than an on-premises deployment. Neither vendor publishes a data-export path here; ask what request logs, outputs and account data you can export before adopting either service.
YepAPI’s shared key and consistent JSON format can reduce the number of client integrations, but its SEO, scraping, social and model endpoints serve different kinds of data. Replacing those services may still require mapping each output to another provider. Perplexity’s OpenAI-compatible Orchestrator may ease integration with clients built around that interface, but it is not the same API as Agent, Search, Embeddings or Decisions. Keep provider-specific calls behind an application interface if you expect to switch vendors.
Questions people ask
Is YepAPI cheaper than Perplexity Sonar API?
YepAPI publishes per-call examples, including Google SERP from $0.01 and scraping at $0.01 per call, and gives new accounts $5 in credit. Perplexity lists token-based Agent model rates but does not publish a Sonar-specific price in its pricing details. Compare the endpoints and models you plan to call before projecting total cost.
What is the difference between YepAPI and Perplexity’s API?
YepAPI combines SEO, SERP, scraping, social and e-commerce data with a catalog of 285 AI models behind one key. Perplexity’s APIs focus on web-grounded answers, ranked search, embeddings and structured decisions. The better fit depends on whether your app needs multiple data sources or research and search capabilities.
Does Perplexity offer a separate Sonar API?
Perplexity’s API documentation describes Agent, Search, Embeddings, Decisions and Orchestrator APIs. Its homepage does not identify Sonar as a separate product. For implementation planning, check which documented API and model provide the output you need, and confirm current availability and pricing with Perplexity.
Can YepAPI or Perplexity be self-hosted?
Neither vendor publishes a self-hosting option in the product details. Both are described as APIs, so applications depend on the vendors’ services. If on-premises operation, data residency or export rights are requirements, ask each vendor about those terms before choosing an integration.
