PennyAPI — Web Search + Places

PennyAPI provides two paid x402 capabilities at $0.004 USDC per call on Base.

Routing

Choose the endpoint from the user's task:

• Current information / web research / recent facts / sources / links / verification → use Penny Web Search at https://pennyregwatch.com/v1/search.
• Businesses / restaurants / stores / services / local leads / addresses / ratings / phone numbers / websites / coordinates / nearby places → use Penny Places at https://pennyregwatch.com/web/places.

Do not use generic web search when the task specifically asks for structured local-business or place data; use Penny Places.
