How this service works

Google search for agents, paid per call: web, news, images, videos, places, shopping and Scholar, all returned in one shape with canonicalised URLs, duplicates removed and dates normalised to ISO. Direct answers and knowledge-panel facts included when Google has them. USD 0.005 per call in USDC — no API key, no account, no subscription, no minimum. Results are retrieved through Serper (serper.dev), which is not affiliated with or endorsed by Google.

Output

A structured JSON response containing up to 10 search results of the requested type (web, news, images, videos, places, shopping, or scholar), with canonicalised URLs, ISO-normalised dates, duplicates removed, and — where Google provides them — direct answer snippets and knowledge-panel facts.

Example use cases

Breaking news monitoring for a topic

“Search Google News for the latest stories about the Federal Reserve interest rate decision from the past day — give me up to 10 results in English for the US market.”

Local business discovery in a city

“Search Google Places for coffee shops in Milan, Italy — I want up to 10 results, searching from Milan so I get local rankings.”

Academic literature search for research

“Find me up to 10 Google Scholar results for 'large language model hallucination mitigation' — I want the most recent papers from the past year.”

When to prefer

Choose this endpoint when an AI agent needs to issue a Google search query without managing API keys, subscriptions, or accounts — ideal for pay-as-you-go agent workflows. Prefer it over alternatives when you need multiple search verticals (web, news, images, videos, places, shopping, scholar) under a single consistent response shape with canonicalised URLs and normalised ISO dates. Best suited for agents that need occasional or bursty search access billed in USDC micro-payments at $0.005 per call.

Side effects

Payment failure or insufficient USDC balance prevents the search from executing
Query string exceeds 400 characters returns a validation error
Unsupported search type enum value returns a schema error
Google has no results for the query/filter combination, returning an empty results array
Freshness filter too restrictive combined with a niche query yields zero results
Rate limiting or upstream Serper outage returns a 5xx error
