How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

Example use cases
SEO keyword research lookup
“Search Google for 'affordable project management software for startups' and show me the top 10 organic results with their titles and URLs so I can see who's ranking.”
Real-time news search
“Look up the latest Google search results for 'Federal Reserve interest rate decision 2025' so I can see what's being reported right now.”
Competitive intelligence gathering

Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/serp-google?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic access to Google search results with per-query micropayment billing via the x402 protocol, particularly in Web3 or DeFi agent workflows where USDC-based pay-per-use pricing is preferred over subscription-based SERP APIs. Ideal for low-volume or sporadic search needs where a flat subscription would be wasteful.
Side effects
- Payment failure: insufficient USDC balance or x402 payment not accepted, resulting in 402 Payment Required
- Invalid query parameters: malformed query object causing upstream SERP API error
- Rate limiting: too many requests in a short window returning 429
- Upstream SERP API unavailability returning 502 or 503
- Empty results: query returns no matching SERP listings
- Malformed request body causing 400 Bad Request
