The toll network
for AI agents.
Agents pay per request in stablecoins. TOLLA puts a cap on every wallet, a health check on every merchant and a receipt on every toll.
Live Lanes and Scan read the public x402 index. Pass, Plates and Booth are in build.
01 · How a toll clears
One request.
One toll. One receipt.
An agent calls an API. The API names its price with HTTP 402. The agent's Pass checks the cap, signs, and the toll settles on-chain before the answer comes back.
- 01
Agent calls
Any HTTP request to a paid API. No account, no API key.
GET /v1/forecast - 02
Booth quotes
The merchant answers 402 Payment Required with a price and where to pay.
402 · 0.002 USDG - 03
Pass checks the cap
Per call, per day, per merchant. Over the cap, nothing is signed.
within cap → sign - 04
Toll settles
A facilitator moves the stablecoin on-chain. Only after the API answered.

Receipt
Payer, merchant, amount and transaction, checkable by anyone.
200 OK · receipt
Prices in this diagram are an example. Steps 03 to 05 run through Pass and Booth, which are in build.
02 · The network
Six booths.
One road.
Every part of an agent payment has its own booth. Two are open today with public data. The rest ship in the order below, each with its own status.

Counted by wallets
that actually paid.
Listings are cheap. Paying wallets aren't. Scan ranks the x402 economy by distinct paying wallets in the last 30 days and flags lanes where a few wallets make most of the calls.
04 · Rules of the road
Built so an agent
can't overspend.
Agent wallets fail in boring ways: no limits, keys in plain text, paying for errors, numbers nobody can check. These are the rules TOLLA is built on, each marked with where it stands today.

If one is ever launched, its contract appears here and on @useTOLLA at the same moment. Anything called TOLLA before that isn't ours.
