Bandwidth agents can buy.

Pay-per-request proxy egress for AI agents. USDC per call over x402, settled on-chain through Circle Gateway. No keys. No plans. The wallet is the access.

The problem

The web wasn't built for agents that pay their own way

0
Rate-limited

429 the moment you scale. Agents get throttled and IP-banned the second they scrape at volume.

451
Geo-blocked

Half the web is region-walled. An agent stuck behind one IP can only ever see one slice of it.

401
Key sprawl

Per-site auth, plans, and invoices don't fit autonomous agents. Subscriptions assume a human signs up.

How it works

Four steps. The wallet is the API key.

01

Discover

Agent GETs the free /catalog — reads the $0.001 price and the egress IP. No signup.

GET /catalog → 200 { price: "$0.001", egress: "92.5.84.57" }
02

Pay

The unpaid request returns 402. The agent signs a USDC payment from its Circle wallet and retries.

GET /proxy?url=… → 402 → pay $0.001 → retry
03

Relay

Circle Gateway settles on-chain — gaslessly, we never touch a key. Bytomic forwards the fetch through its egress IP and streams the response back.

settle USDC → egress 92.5.84.57 → 200 + body
04

Receipt

Every call lands in a spend ledger with its tx hash. The agent stops the moment it hits its budget cap.

200 + x-payment-tx: 0x7a3f…e91c · budget 12/100
Live ledger

Both sides of every trade, on-chain

The agent gets data, the operator gets paid — and a clickable receipt proves it.

Why it wins

Standing on the Circle agent stack

Circle Agent Wallet
The agent's payment identity & budget.
x402
HTTP-native 402 payments per call.
Circle Gateway
Gasless USDC settlement, no key held.
Claude Agent SDK
The autonomous buyer driving it all.
Base
On-chain receipts for every fetch.
Use cases

Any agent that needs an IP that isn't its own

Research agents

Reach paywalled and geo-restricted data sources that block a datacenter IP on sight.

Market scrapers

Pull prices and listings at volume, dodging the 429s that kill a single-IP crawler.

QA agents

Geo-test a product from many exits — verify what a user in another region actually sees.

Any autonomous agent

Metered egress is a primitive: pay cents per call, no plan, no key, the wallet is the access.
