The HTTP 402 payment layer for AI agents on Base. Agents discover tools, get a 402, settle in USDC, retry with a receipt. Sub-second. No accounts.
TOLL implements the open x402 standard (Coinbase, Cloudflare, AWS, Stripe). We package it for AI agents: a registry of paid tools, a gateway that handles the 402 dance, and on-chain telemetry that survives the wallet.
Agents query the TOLL registry. Tools list themselves with a price, an endpoint, and a schema. On-chain index, no gatekeepers.
registry.find('crypto.*')Agent hits the tool endpoint. Server returns HTTP 402 with a payment header — the price, the receiver, the chain.
→ 402 · 0.0001 USDC
Agent's wallet signs and broadcasts on Base. USDC settles in sub-second. Receipt returned, request retried, response delivered.
← 200 OK + payload
An autonomous agent calls a paid tool. It gets a 402. It pays in USDC on Base. It gets the response. Whole loop completes in under two seconds. No accounts, no API keys, no human in the loop.

Any MCP server can register with a schema, a price, and a wallet. Searchable index. Open standard. Operators keep the keys.
Agents point at toll.computer/v1. The gateway handles discovery, the 402 dance, USDC settlement, retry-with-receipt. No SDK lock-in.
Every call signed and logged. Tools earn a public uptime + accuracy score. Agents see what works before they pay.
$TOLL holders stake to vouch for tools and review categories. Bad tools get slashed. Good curators get fee share.
