How this service works
14 paid data endpoints for autonomous agents and developers. Covers crypto intelligence (token, chain, Solana, gas), markets (FX, market pulse), location (weather), and research (news, brief). Each route aggregates multiple public sources into one stable schema with a single USDC payment over x402 on Base.
Output
Returns a JSON object containing an array of ranked web results (each with URL, title, snippet, position, and source engine), plus total result count, search time in milliseconds, data sources used (SerpApi), and an as-of timestamp.
Example use cases
Real-time research on emerging topics
“Search the web for 'quantum computing breakthroughs 2025' and return the top 10 results in English, localized for the US with safe search on.”
Localized product information lookup
“Can you search for 'affordable electric cars Germany 2025' with country set to DE and language to de, and return the top 5 results?”
Paginated content discovery for analysis
“Search for 'climate change policy reports' and get results 11 through 20 — I want the second page of results in English from the US with safe search active.”
Technical details
Endpoint
POSThttps://meld402.vercel.app/api/web/searchWhen to prefer
Choose this endpoint when you need aggregated web search results from multiple engines (Google, Bing, DuckDuckGo) in a single stable schema, and you want per-request micropayment billing via USDC on Base rather than a subscription. Ideal for autonomous agents that search intermittently and need localized, paginated results without managing multiple search API keys.
Side effects
- Empty or missing query returns validation error
- Query exceeding 500 characters rejected
- Invalid country or language code may return unexpected locale results
- Upstream SerpApi degradation results in partial or empty results with degraded source flag
- Payment failure over x402 blocks the request before execution
- num outside 1-20 range returns validation error
