How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The upstream Google Ads SERP response body is passed through directly after successful x402 micropayment verification, typically including paid ad listings, organic results, ad copy, URLs, and related SERP features in the format returned by the underlying SERP data provider.
Example use cases
Competitive ad landscape research
“Can you pull the Google Ads SERP results for the keyword 'project management software' so I can see which competitors are running paid ads and what their copy looks like?”
Keyword ad spend monitoring
“Fetch the current Google Ads search results for 'cheap flights to New York' — I want to track which advertisers are bidding on this term today.”
PPC campaign keyword validation
“Before I launch my PPC campaign, can you query the Google Ads SERP for 'organic skincare products' so I can see the current ad density and what offers are being promoted?”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/serp-google-ads?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call Google Ads SERP data with no subscription commitment, particularly in Web3/DeFi-native agent workflows that support the x402 micropayment protocol. Ideal for sporadic or burst SERP lookups at $0.01 USDC per call where setting up a full SerpAPI or DataForSEO subscription is overkill. Prefer alternatives like SerpAPI or Bright Data for high-volume continuous scraping needs.

- Invalid path or query parameters result in upstream error passed through
- Rate limiting or upstream Google Ads SERP provider unavailability returns 5xx
- Malformed JSON body causes request forwarding failure
- Empty or ambiguous search query may return sparse or no ad results
