for the agentic era

Tollway is an open protocol for AI agent web access. Identity headers, policy enforcement, and USDC micropayments — all in a single middleware you drop into any Express or Next.js app.

✓ tollway.json served ✓ DID identity headers ✓ 402 payment flow Ed25519 signing USDC on Base MIT + CC BY 4.0
◈

Identity

Every agent request carries a did:key DID and an Ed25519 signature. Servers know who is asking.

◎

Policy

Sites publish /.well-known/tollway.json declaring what agents can do, how much it costs, and attribution rules.

◐

Payments

HTTP 402 + x402 standard. Agents pay in USDC on Base. The whole round-trip happens in milliseconds.
