Technical details
Endpoint
POSThttps://cr4vvol.vercel.app/api/searchWhen to prefer
Choose this endpoint when you need live web search or scraping without API keys, subscriptions, or rate-limit agreements — especially in autonomous agent workflows where pay-per-request USDC billing via x402 is preferred over monthly subscription models. Good for ad-hoc lookups where you don't want to manage credentials.
Side effects
- Payment failure if USDC balance is insufficient for x402 transaction
- Empty or irrelevant results if query is too vague
- Query parameter missing returns validation error
- Rate limiting or timeouts for very broad queries
- num parameter out of range may cause unexpected result counts
