Best x402 USDC payments APIs: send and receive programmatically

Looking for APIs that send or receive USDC in code—especially for AI agents—without a card checkout? These 22 payment listings in our directory accept USDC. Most use the open x402 HTTP payment flow: the server answers unpaid calls with HTTP 402 and a price; the client pays in USDC and retries. Listed prices are from each provider’s public endpoint or site as recorded in our directory—not a fee ranking.

Which networks offer lower costs for USDC payments?

On-chain network (gas) fees vary by chain and congestion; we do not publish live gas oracles here. In our directory, Base and Solana appear most often on USDC x402 payment listings. Per-call API prices we record for payment tools commonly sit from about $0.001 to a few cents of USDC when a fixed price is published—see each tool page for the price our unpaid check last saw in the 402. For shopper checkouts (not agent HTTP payments), see crypto payment gateway fees compared.

Payment listings that accept USDC (22)

A to Z by activity in our directory. Facilitators settle signed x402 payments on-chain so API sellers do not run their own nodes. This is not an endorsement.

Frequently asked questions

What APIs can I use to send and receive USDC programmatically?

Use an x402-compatible payment API or facilitator from the table above, or charge your own API with x402 middleware so clients pay USDC per request. Start with how to accept USDC for your API and the payments category.

Is x402 the same as a crypto payment gateway?

No. Gateways (BitPay, CoinGate, BTCPay, Stripe stablecoins, and others) are built for checkouts and invoices. x402 is for metered HTTP APIs and agents. You can use both.
