Paste

A base URL, a spec URL, or raw JSON/YAML. We find your OpenAPI spec if you have one.

Price

Each route gets a suggested per-call price. Edit any of them, untick what stays private.

Publish

Sign one message with your wallet. Routes go live at coinlight URLs that answer 402.

Get paid

Agents pay USDC on Solana. Your 98.5% is paid out to your wallet automatically by a daily payout run.

Transparent fees

One flat 1.5% on paid calls. No subscription, no setup fee, nothing on unpaid probes. Per $100 of sales:

Gateway	Fee	You keep	Chains
Coinlight	1.5%	$98.50	Solana (Base soon)
Gatefare	10%	$90.00	Base

Gatefare's 90/10 split is from gatefare.io, checked October 2026.

What every seller gets

One listing per route. Each route has its own URL, price, input schema and x402 discovery metadata, so agents find exactly the call they need.
A public page. A search-friendly page listing your endpoints, prices and example calls.
Your own MCP server. Claude, Cursor and other MCP clients can add your API as tools with one URL.
A revenue dashboard. Gross, fees, net, payouts and every payment with its on-chain transaction.
Safe by default. Buyers are charged only when your API answers. Failed upstream calls don't settle.
