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 JSON object with a recommended source (title and origin URL/label), an alternatives array of up to three other sources, payment confirmation (paid: true), settlement details (network and transaction hash on Base), and the toll cost in USD ($0.001).

Example use cases

AI agent finds API research source

“I'm building an agent that needs to find reliable sources for researching AI transcription APIs — use VIA to route my intent 'find a speech-to-text API' in the information market for the US in English and tell me what source it recommends.”

Travel service sourcing in Brazil

“My agent needs to find the best web source to research travel services available in Brazil — can you route the intent 'find travel booking services in Brazil' through VIA's research router, market set to travel, country BR, language Portuguese?”

E-commerce product comparison sourcing

“Help me find a curated research source for comparing e-commerce platforms — route the intent 'compare online store builders' through VIA in the commerce market, US, English, and show me the recommendation and any alternatives.”

Technical details

Endpoint

When to prefer

Choose this endpoint when an AI agent needs to discover curated web research sources for a plain-language intent, rather than doing raw web search itself. Ideal when the agent needs a trusted, pre-vetted source recommendation rather than raw search results, and when the use case fits a defined market category (services, commerce, information, travel). Prefer over generic web search when sourcing quality and curation matter, and when x402 USDC micropayment infrastructure is already in place.

Side effects

Intent too vague or too short (minLength:2 not met) — returns validation error
Unsupported market enum value — returns schema validation error
Invalid country code format (not 2-letter ISO) — returns pattern validation error
Payment failure or insufficient USDC balance — x402 payment not settled, request rejected
No matching research sources found for intent — alternatives array may be empty
Rate limiting or service unavailability — returns 5xx error
