How much does the OpenWeb Ninja search API cost?
The Real-Time Web Search API has a free tier of 100 requests a month at one request per second. Pro is $25 a month for 10,000 requests plus $0.003 for each extra, Ultra is $75 for 50,000, and Mega is $150 for 200,000, which our arithmetic puts at $0.75 per 1,000. Pay-as-you-go is $0.005 per call. Each API in the catalogue has its own plans, sold on OpenWeb Ninja's portal or on RapidAPI.
What does the OpenWeb Ninja web search API return?
It returns Google results as structured JSON: organic results with title, URL, snippet and position, plus AI Overviews, AI Mode answers, Knowledge Graph, People Also Ask, related searches, and video, place and news results. One request returns up to 100 organic results, and a query can go to 500 where Google has them. The vendor puts response times at roughly 0.5 to 8 seconds, depending on the endpoint and parameters.
Does OpenWeb Ninja have an MCP server?
Yes. You add it to Claude Code with one command that runs the @openwebninja/mcp-server package through npx and passes your API key. One connection exposes tools for all of its 50-plus APIs to Claude, Cursor, Windsurf or any other MCP client. There's also an agent skill that takes a plain-language request, picks the right API, runs it, and returns JSON or CSV.
What is x402 payment on OpenWeb Ninja?
x402 lets an agent pay for a call in USDC inside the HTTP request itself, without an account, API key or subscription. That suits autonomous agents that discover a data source mid-task and need to pay for one lookup. For a product with predictable volume, a normal subscription with an API key is cheaper and easier to account for, so treat x402 as a convenience for agent experiments.
What are the risks of building on OpenWeb Ninja?
Three things are worth checking. Several APIs, including the Copilot one, are labelled unofficial wrappers around other companies' products, and those can break or draw terms-of-service objections. Google scraping carries the same legal exposure as the rest of the SERP API category. And it's a small team, reportedly two to ten people, so ask for a custom plan with a hard request cap and an SLA if you depend on it in production.
