how it works

Three ways in.

  1. 01

    Curl it free

    Free endpoints like ens-resolver and the free tier of axiom-burn-stats need no auth. Standard HTTP GET. Test from the terminal.

  2. 02

    Pay with x402

    Paid endpoints return HTTP 402 with payment requirements. Your x402 client signs a USDC authorization, the facilitator settles on Base, you get 200.

  3. 03

    Or hold the Pass

    Sign a SIWE message from a wallet holding โ‰ฅ1 AXIOM Tool Pass NFT. Server verifies on-chain, paywall skips. Unlimited calls.
