API · Pricing

One payment, one key

The website and the Telegram bot are free. The API is paid: buy a credit pack with one payment from your Solana wallet, in USDC, or in $FEYN at 15% off. There is no account and no e-mail. You get an API key, and the key is the account.

Payments open at the $FEYN launch.

Until then there is nothing to buy. The website, the WebSocket and /v1/token are free, within per-IP rate limits; no key needed.

Good to know

  • Every pack gets the same data. Packs differ only in rate limit and in how long the key lasts.
  • A key's lifetime starts when its payment confirms. Credits left at expiry expire with the key.
  • The key is shown once, and Feyn keeps only a hash of it. Lost it? The paying wallet can sign for a new secret (key recovery).
  • $FEYN is priced from a 10-minute average of its trades; a $FEYN quote holds for 60 seconds. SOL is not accepted.
  • You approve one payment in your wallet. Feyn pays the network fee.
