Who it is for

Sam has a great weather-for-farmers API. Toll Booth wraps it in x402, lists it in an agent directory, and USDC drips in from agents calling it overnight.

Why it is new

What exists today, and what this does differently

Why own your own

Wrap-and-list x402 tooling is live; the value is a simpler owned storefront, not a new mechanic.

Closest things out there

Polygon Agentic Services wraps existing REST endpoints in x402 and lists them, Coinbase x402 Bazaar handles agent discovery, and Ag402 and 1ly.store offer similar sell-an-endpoint flows.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

How it earns for you

One booth is free and the owner keeps a small share of settled volume; builders who need more endpoints, per route pricing or exports pay monthly.

One boothFree plus 2% of settled volumeOne endpoint, one price, a directory listing and the morning tally
Stall$12 a monthUp to five endpoints, per route pricing, free lane, caps and refunds on stale answers
Market$49 a monthUnlimited endpoints, custom domain, team access and CSV exports

Volume fee set by the owner (default 2 percent of settled volume on free booths). Payments settle directly to the builder's wallet; the app never holds funds.

Prices are yours to set. Illustrative, not a promise of income.

The pitch, ready

Put a pay per call booth in front of any API, and AI agents pay a fraction of a cent in USDC for every call.

Problem: Small builders have useful APIs but no way to charge agents per call without accounts, keys and invoices.

Solution: An x402 booth that answers unpaid calls with a price, settles USDC straight to the builder, caps floods, keeps a free lane, and lists the booth where agents look.

Why now: x402 makes HTTP payments native, USDC on Base settles for fractions of a cent, and agents are now calling APIs on their own.

Market: Indie API builders, data providers and prompt makers selling to AI agents.

The ask: Pilot with 100 builders at a local builder night and grow through named 402s and directory listings.

Funding is never guaranteed. Check each program's rules.

For hackathons and demo days

Your 2 minute demo

  1. Home: meet Sam in Eldoret, whose frost API is about to become a shop for machines.
  2. Booth: set the price and cap, keep the farmers' SMS lane free, and publish to directories.
  3. Live: a planner agent pays and gets an answer, a bot flood is capped, a scraper gets a 402.
  4. Tally: wake up to 18,400 paid calls and share the card.
  5. Booth: Stall unlocks more endpoints through the USDC checkout.
  6. Owner Agent: see the slow facilitator handled and the running costs.
  7. Owner Revenue: change the volume fee and plan prices, and preview the Plans sheet.
  8. Owner Growth and Roadmap: run a builder night, then request prompt and model booths.

Many hackathons require code written at the event. See the Regatta Boardfor each race's rule.

BLUEPRINT

Why it matters and how it really works

The need

Lots of people own a small, useful API or prompt. Agents already want to call these, but billing a machine with sign ups, keys and invoices is too much work, so the tool stays free and gets scraped, or gets locked away.

What exists and what is new

This exists. Polygon Agentic Services wraps existing REST endpoints in x402 and lists them, Coinbase's x402 Bazaar handles agent discovery, and Ag402 and 1ly.store offer similar sell-an-endpoint flows. What this app adds is a simpler storefront you own under your own name: one endpoint in a minute, a reserved free lane for your human users, per payer caps, and settle-only-on-fresh-answer refunds by default. It is a packaging and ownership play, not a new mechanic.

The data it runs on

Your endpoint URL and its responses (forwarded, not stored beyond short logs), the price you set, payment receipts in USDC on Base or Arc, per payer request counts for rate caps, and directory search terms that lead agents to you.

1.The mission

Let anyone with a useful little tool open a shop for machines, without giving up the people who use it for free.

2.Why people can't resist it

Money arrives while you sleep A morning tally of last night's paid calls is a small, real reason to open the app every day.

No code change Paste a URL, set a price, done. The booth is a proxy that speaks x402 in front of what you already run.

Your users stay free A reserved free lane means charging machines never costs your community anything.

3.How it works for real

Proxy: A small edge worker (for example a Cloudflare Worker or Vercel function) sits in front of the owner's endpoint and answers unpaid requests with HTTP 402 and an x402 payment requirement.

Payments: x402 exact scheme with USDC on Base, or on Arc where supported. A facilitator such as the Coinbase CDP facilitator verifies and settles, so the owner never holds agent keys.

Settle on fresh answer: The proxy verifies payment first, calls the upstream API with a timeout, and settles only if a fresh response comes back. Timeouts and errors are not charged.

Caps and lanes: Per payer rate caps (for example 300 calls a minute, then 429) and a reserved route or API key for the owner's free human users that is never sold.

Discovery: Listing metadata (description, schema, price) published to x402 discovery directories and agent tool registries, rewritten from the search terms agents actually use.

Earnings page: A simple dashboard reads settlement events from Base or Arc and the proxy's logs to show calls, revenue, refunds and top callers.

Notifications: A morning digest by email or Telegram with last night's tally and one suggested change, which the owner approves before anything is published.

4.Cost per use and pricing

Per paid call: Base gas is usually a fraction of a cent, and the Coinbase CDP facilitator lists a free tier of 1,000 transactions a month and about $0.001 per transaction after that, so very cheap calls are best batched or priced at $0.002 or more. Edge proxy hosting is often free to a few dollars a month at this scale. Example month: 500,000 paid calls at $0.002 is $1,000 gross; facilitator fees around $500 at list price unless batched or self hosted, hosting about $5. Check current facilitator pricing before launch.

One booth Free plus 2% of settled volume
One endpoint, one price, one directory listing and the morning tally.
Stall $12 a month
Up to five endpoints, per route pricing, free lane, caps and refunds on stale answers.
Market $49 a month
Unlimited endpoints, custom domain, team access and CSV exports for accounting.

5.Growth loop

Every listing is discoverable by agents, and every 402 response carries the booth's name, so builders who see one tend to open their own. Owners share their morning tally card, which is a natural, honest brag.

6.Risks and guardrails

Low demand: Listing does not guarantee callers. The app should say so plainly and show real search demand before the owner pays for anything.

Facilitator fees on tiny prices: Per transaction fees can exceed very small prices. Warn when price is below fee, suggest batching or a higher floor.

Abuse and floods: Paid floods can still starve capacity. Per payer caps and a reserved free lane are on by default.

Upstream failures: Charging for stale or failed answers breaks trust. Settle only after a fresh response, and show refund rate publicly.

Legal and data rights: The owner must have the right to sell the data they proxy, and may need to handle tax on income. The app does not give tax or legal advice.

7.Build order

  1. Edge proxy that returns 402 and forwards paid requests for one URL
  2. x402 settlement in USDC on Base through a hosted facilitator
  3. Price, cap and free lane settings page
  4. Directory listing metadata and one-click publish
  5. Earnings page from settlement events
  6. Morning digest with one suggested change

8.Where this is going

  1. Now
    One endpoint, one price, a booth on Base that pays a small server bill.
  2. Next
    Several endpoints, smarter pricing from what agents ask for, and settlement on Arc for USDC native flows.
  3. Later
    Small data owners in farming, transport and local news bundle their booths into shared markets agents trust.
  4. The world it builds
    Useful local knowledge gets paid for by the machines that use it, and stays free for the people it was made for.

Why own Toll Booth

Toll Booth turns any API or prompt you own into a shop that AI agents can buy from at any hour. Owning it means the endpoints, the pricing, and every USDC payment land in your wallet, and your onchain record shows a real machine to machine business. On someone else's marketplace, they set the rules and take the margin.

What’s stopping you?

“I can't code.”

You do not need to. Toll Booth ships ready to deploy, and every path here is written for non coders. When you want to change something deeper, you can hire help or ask DEPLOYR support.

“Is it really mine?”

Yes. It is deployed from your wallet, the contract address is public, and the brand, users, and revenue are yours. DEPLOYR does not hold your keys or take a cut of your app's revenue.

“What if no agents call my endpoint?”

That is a real risk. Agent traffic is still growing. Start with a tool people already ask you for, list it in agent directories, and track calls. Do not quit anything based on it.

“What if my API goes down?”

Paid calls to a broken API annoy agents and their owners. Set up a simple uptime check and refund or pause pricing when it fails.

“Is selling API access legal?”

Selling your own data or tool is usually fine. Do not resell someone else's API unless their terms allow it, and respect privacy rules for any personal data.

The million-dollar ladder

You earn per call from agents paying in USDC, plus optional monthly fees from other API owners if you host endpoints for them. $1M a year is a target, not a promise.
