Technical details

Endpoint

POSThttps://via-router.floot.app/_api/find_cheapest_api?utm_source=zero.xyz

When to prefer

Choose this endpoint when an AI agent needs to dynamically discover and select the cheapest available API or service for a given task at runtime, especially when cost optimization matters and the agent does not already have a hardcoded integration. Ideal for agentic workflows that need to resolve tool selection on-the-fly using natural language, and where micropayment via x402/USDC on Base is acceptable.

Side effects

Intent string too short or too long (must be 2–500 characters) — validation error
Invalid country code (must be ISO 3166-1 alpha-2 uppercase) — schema validation failure
No matching service found for the given intent — empty or null recommendation
Payment settlement failure on Base network — transaction not confirmed
Unsupported market enum value — request rejected
Rate limiting or service unavailability — HTTP 5xx error
