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
Returns a paid:true confirmation, contract pass/fail, a top recommendation with title, a list of alternative options, and a settlement object containing the Base network transaction hash for the x402 USDC payment.
Example use cases
Sourced API comparison for agent workflow
“Compare APIs for sending transactional emails to users — search in the services market for the US in English and tell me which one you'd recommend for my agent to use.”
Commerce product sourcing for a buyer agent
“I want to buy ergonomic office chairs for a team of 10 — look in the commerce market for the US in English and recommend the best sourced option with alternatives.”
International service discovery in Portuguese
“Find me the best payment processing service available in Brazil — search in the services market, in Portuguese, and give me a recommendation with alternatives.”
Technical details
Endpoint
POSThttps://via-router.floot.app/_api/buyer_contract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to compare, evaluate, and receive a ranked recommendation across multiple APIs, services, or commercial products — especially when micropayment-gated access via x402 on Base is acceptable. Prefer it over static API directories when you need dynamic, intent-driven routing with a buyer-contract guarantee and sourced research rather than a simple search index.
Side effects
- Payment insufficient or failed — x402 payment not accepted, no result returned
- Intent too vague or too short (minLength:2 not met) — validation error
- Invalid country code (not ISO 3166-1 alpha-2) — schema validation failure
- Unsupported market value (not 'services' or 'commerce') — enum validation error
- No matching results found — empty alternatives array, contract.passed may be false
- Network or Base chain settlement failure — transaction hash missing or error state
