How this service works
40+ public web-data, SERP, e-commerce, real-estate, finance and AI-search APIs, payable per call over x402 (USDC on Base, Polygon, Arbitrum). No account or API key required. Most endpoints $0.003; AI-model endpoints $0.005.
Output
A JSON response containing the AI-generated reply from Google Gemini (in plain text or markdown depending on the flag), along with a conversation_id that can be used to continue the conversation in subsequent calls.
Example use cases
Multi-turn Gemini research assistant
“Start a conversation with Gemini asking it to help me research the pros and cons of solar panel installation for a home in Arizona, and keep the conversation ID so I can follow up with more questions.”
Quick Gemini fact check
“Ask Google Gemini whether the claim 'coffee was first discovered in Ethiopia' is historically accurate, and return the answer in plain text.”
Gemini-powered writing help
“Send this paragraph to Gemini and ask it to rewrite it to sound more professional, returning the response in markdown: 'We need to get more customers and our website kinda sucks so we should fix it soon.'”
Technical details
Endpoint
POSThttps://x402.openwebninja.com/gemini/chatWhen to prefer
Choose this endpoint when you need access to Google Gemini's chat capabilities without registering for a Google API key or committing to a subscription — ideal for agents that want to make occasional Gemini calls and pay only per use via USDC on Base, Polygon, or Arbitrum. Prefer this over direct Google Gemini API when operating in a crypto-native payment environment or when avoiding API key management is a priority.
Side effects
- Payment not included or insufficient USDC causes 402 response
- Invalid or malformed message field returns error
- Expired or invalid conversation_id may start a new session instead of continuing
- Network timeout if Gemini upstream is slow
- Empty message field may return an error or empty response
