PAY-PER-QUERY SEO API FOR AI AGENTS

The Toll Booth

Your AI agent is brilliant. And blind. Give it eyes — backlinks, keywords, SERP data — paid per query in USDC. No API key. No subscription.

THE PROBLEM

Your agent can write, code, and reason. But ask it what ranks on Google, who links to your competitor, or which keywords are worth money — nothing. It can't see the live web. Every SEO decision it makes is a guess.

THE FIX

Wholesale SEO data with a toll on it. Your agent asks a question, pays a few cents in USDC via x402 on Base, and gets JSON back. It pays for exactly what it uses. Nothing more.

How an agent buys

# 1. Agent calls the endpoint
POST /api/seo/backlinks
# 2. Gets an HTTP 402 challenge
402 PAYMENT-REQUIRED { amount, asset, payTo }
# 3. Agent signs USDC payment on Base
PAYMENT-SIGNATURE → retry with header
# 4. Verified settlement → JSON delivered
200 { backlinks: [...] }

No API key. No signup. No monthly plan. Payment is the authentication.

THE HONEST BIT

It's not magic. It's wholesale SEO data with a toll booth on it. If your agent needs live search data — competitor link graphs, ranking keywords, commercial-intent terms — this is the cheapest way to buy exactly what it uses. If it doesn't, don't pay. That's the whole pitch.

Questions

What is The Toll Booth?

A pay-per-query SEO API built for AI agents. Your agent asks for backlink, keyword, SERP or domain data, pays a few cents in USDC via x402 on Base, and gets JSON back. No API key, no subscription.

How does an agent pay?

Via x402: the agent calls the endpoint, receives an HTTP 402 payment challenge, signs a USDC payment on Base, and retries with the payment signature. Settlement is on-chain and verifiable.

Do I need an API key?

No. There are no API keys. Payment is the authentication — the x402 challenge-response carries the authorization.
