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: a decision brief summarizing the recommendation, a list of selection rationale points explaining why the top option leads, a list of watchouts (unverified facts to check), the number of sources considered, a paid confirmation flag, tier label ('deep'), and a blockchain settlement object with the Base network transaction hash confirming the x402 USDC payment.

Example use cases

API selection for a developer

“I need to pick the best SMS API for my startup in the US — can you use VIA Router to compare my options in the services market and give me a decision brief with rationale?”

Travel service comparison for an agent

“Compare travel booking platforms for flights and hotels in Portugal using VIA Router — market is travel, country PT, answer in English.”

E-commerce tool research for a merchant

“I'm launching an online store in Brazil and need to choose a payment and checkout solution — run a deep route on VIA Router for the commerce market, country BR, in Portuguese.”

Technical details

Endpoint

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

When to prefer

Choose this endpoint when an AI agent or user needs a buyer-side recommendation across multiple competing services, APIs, products, or information sources — especially when the decision requires sourced research and ranked rationale rather than a raw search result list. Ideal when the user has a clear intent but is unsure which vendor, API, or service to select. Prefer this over generic web search when you want a structured decision brief with watchouts and selection reasoning, and when micropayment via x402 USDC on Base is acceptable.

Side effects

Intent too vague or too short (minLength 2, maxLength 500) — returns validation error
Invalid country code (must be ISO 3166-1 alpha-2 uppercase, e.g. 'US') — returns 422
Insufficient USDC balance or x402 payment failure — request not processed, payment not settled
Unsupported market enum value — returns schema validation error
Language not in ['en','pt'] — returns validation error
No relevant sources found for intent — may return sparse or low-confidence decision brief
