AXIOM Tool Pass
Lifetime, unlimited access to every AXIOM API and onchain tool — without paying per call.
Generative art revealed at mint. Each pass is a deterministic SVG seeded by its token ID — 6 paper-and-ink palettes, 5 sigil motifs, 4 watermark angles, single/twin variants. No IPFS, no separate reveal date: the moment your mint tx lands, your art is rendered.
AXIOM's tools are paid endpoints — agents pay a small USDC fee in every request (the x402 standard). Holding one Tool Pass skips that paywall for life — no subscription, no API key, no expiry. 1000 supply, 0.005 ETH each, on Base.
Access is enforced onchain via ERC-8257 — the NFT is the gate-pass. Transferable: sell the pass, the buyer inherits the access.

How it works
› The full story — x402, ERC-8257, and how the pass actually works
AXIOM is publishing a suite of onchain tools — APIs and endpoints that agents (and people) can call to query Base data, trade tokens, run signals, etc. Each tool charges a small fee per request, paid in USDC.
x402 is the open standard that makes the payment happen automatically: the endpoint returns HTTP 402 with a price, the caller pays in USDC, the call goes through. No API keys, no accounts, no Stripe setup. Just attach a wallet and pay per call.
ERC-8257 is the registry where these tools are listed onchain. When AXIOM registers a tool, it points the tool's accessPredicate field at the Tool Pass contract. The predicate is what the endpoint checks before charging.
If the caller's wallet holds a Tool Pass, the predicate returns "granted" and the x402 paywall is waived — the request goes through with no USDC charge. Without a pass, the standard per-call fee applies. This is enforced at the protocol layer, not via a discount code or an off-chain auth server.
The pass is an ERC-721 NFT, fully transferable. Sell it on OpenSea and the new owner gets the same unlimited access. Lose it, you go back to paying per call. There is no subscription to renew, no account to migrate, no API key to rotate.
