01. Architecture

one wallet. every paid api.

stop juggling forty api keys and forty billing pages. one mcp endpoint, one usdc wallet, every provider in the catalog. agents call. wallet pays.

Data Layer

per-call billing.

every request is a tiny usdc transfer on solana. no monthly invoice, no overage. you stop calling, you stop paying. that's it.

Drop-in MCP

one mcp endpoint your agent registers once. every provider in the catalog becomes callable. install pay, point at wallet, done.

Provider routing

agent picks the cheapest provider that satisfies the call. wallet pays. failover is automatic. middleware out of the way.

Sub-second settle

payments clear on-chain in ms.

Non-custodial

your wallet, your keys, your cap.

72+ providers

rpc, ai, data, oracles, search.

Open Source SDK

Full programmatic access.

02. Settlement Layer

http 402, settled on-chain.

agent calls a paid api. server responds with 402 and a price quote. wallet signs a usdc transfer on solana. call clears. provider gets paid. no escrow, no api key, no monthly bill.

402proto Active

ON-CHAIN SETTLE

"no more api keys to rotate. no more rate-limit dashboards. agent calls, wallet pays, i stop caring which provider answered. it's the cleanest payment primitive i've shipped against in years."
