Frequently asked questions
Is listing really free?
Yes. You can list any API on PayAPI Market at no cost. We only take a 3% fee on successful payments — if your API doesn't earn, you don't pay us anything.
How does the 3% fee work?
When an AI agent pays your API via x402, the payment is split on-chain: 97% to your wallet, 3% to the PayAPI Market treasury. No invoicing, no monthly bill, no surprise fees.
What do I get with Featured ($49/mo)?
A reduced 2.5% platform fee, a gold badge on your card, always-first placement in search and category filters, and priority inclusion in the MCP tool manifest surfaced to agents. Breakeven vs Free is around $10K/mo in gross revenue.
Do I need a crypto wallet to get paid?
Yes. Payments settle as USDC on Base. You provide a wallet address at listing time. Off-ramp to USD is available through any USDC-supported exchange or bank on-ramp like Coinbase.
Can I change pricing per endpoint?
Yes. Every endpoint can have its own x402 price — from $0.0001 to any amount. Price per request is set in your MCP server configuration; the marketplace reads and displays it automatically.
Do buyers pay monthly subscriptions?
No. The whole point of x402 is pay-per-request. AI agents pay only for the calls they make, in USDC, with no minimum spend and no accounts. This makes your API instantly usable by any agent on the network.
