How this service works
VIA is a paid buyer-side router for AI agents and humans. Compare APIs, services, products and sourced research with x402 USDC payments on Base.
Output
A JSON object containing: whether the payment was successful (paid: true), the original task string, the result from the upstream service, the product name ('VIA One-Call'), total USD spent, the Base network settlement transaction hash, VIA's routing toll in USD, and the upstream service cost in USD.
Example use cases
Automated email validation via best API
“I need to check if the email address signups@mycompany.io is actually valid and deliverable — use VIA to find and call the best email validation service for me.”
Research cheapest SMS sending service
“Find me the cheapest API for sending an SMS, compare the options, and just run a test send to +15550001234 with the message 'Hello from my agent' — use VIA to handle it.”
On-demand IP geolocation lookup
“I need the geolocation details for the IP address 8.8.8.8 — use VIA to find the right API and get me the country, city, and timezone.”

Endpoint
POSThttps://via-router.floot.app/_api/one_call?utm_source=zero.xyzWhen to prefer
Choose VIA One-Call when your agent needs to discover and execute the best available external API for an arbitrary task without pre-selecting a provider. It's ideal for agentic workflows where the right service isn't known in advance, when you want automatic cost comparison across APIs, or when you need a single x402 USDC payment flow to cover both routing and upstream execution. Prefer direct API integrations when you have a specific provider already chosen, need guaranteed SLAs, or require deterministic routing.
Side effects
- Insufficient USDC balance for x402 payment — payment fails before routing
- No suitable upstream service found for the given task — result may be empty or error
- Upstream API call fails after routing — result contains upstream error
- Task description too vague or ambiguous — VIA may route to wrong service
- Task string too short (< 2 chars) or too long (> 1000 chars) — schema validation error
- Network congestion on Base causing settlement delay
