Transparent Pricing

No subscriptions. No hidden fees. Pay only when your API gets called.

💰

What does it cost?

You set the price. Typical Blinks charge $0.01–$0.10 per API call. Solana gas fees are ~$0.0001 (fractions of a penny). No monthly subscription or platform fees.

🔓

Do buyers need an account?

Nope. Buyers just need a Solana wallet (Phantom, Solflare, etc.). No signups, no API keys, no credit cards. One click, one signature, done.

How fast do I get paid?

Instantly. Powered by ONCHAIN.fi for sub-second settlement in USDC. Payments hit your wallet on-chain within 2.1 seconds on average. No waiting, no chargebacks.

🛡️

Are there hidden fees?

Zero. What you charge is what you earn. Blink402 doesn't take a cut. Only Solana network fees apply (~$0.0001 per transaction).
