How this service works

Example use cases

Finding the right SMS API

“I need to pick an SMS notification API for my app — can you search and compare options and give me a cited recommendation? I'm in the US, English preferred.”

Sourcing a product data feed

Researching AI travel booking tools

Technical details

Endpoint

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

When to prefer

Choose this endpoint when an AI agent needs a cited, opinionated recommendation for an API, service, or product rather than a raw web search. It is especially suited for buyer-side agent workflows where the agent must evaluate and select among tools or vendors and where a micropayment (x402/USDC) model is acceptable. Prefer this over generic search APIs when you want structured output (title, source, alternatives) rather than raw HTML or snippets.

Side effects

Intent too vague or short (minLength:2 violation) — returns validation error
Unsupported market enum value — returns schema error
Invalid country code format — returns pattern validation error
Payment failure or insufficient USDC balance — x402 payment not settled, no answer returned
No relevant results found for the intent — alternatives array may be empty
Rate limiting or upstream web search failure — may return empty or error response
