No OAuth, no billing portals, no API keys. Fanfare is built x402-native — payment discovery is in the HTTP response itself.
Agent calls any endpoint. Gets HTTP 402 with price, asset, and payTo address in the response header.
Agent signs an EIP-3009 authorization on Base. No gas, no wallet popup. The x402 client handles it.
Same request with PAYMENT-SIGNATURE header. Middleware verifies on-chain and returns the data.
$1 of USDC gets you 1,000 standard calls. Bundles pack multiple data sources into a single payment — or go unlimited for a season with a pass.
Live data means polling — and you shouldn't pay for every poll. Fanfare runs the latest x402 v2 with Sign-In-With-X: one payment opens a window, then you re-access by signing with the same wallet. No re-settling, no second charge.
One payment covers a polling window — late-swap 60s, DFS slate 5 min, game previews 15 min. Re-fetch by signing, at zero extra cost, until it expires.
Buy the MLB Fantasy Season Pass once and every DFS slate endpoint is unlocked through the postseason — proven by your wallet signature, not another payment.
USDC on Base via EIP-3009 — no gas, no popups. Built on x402 v2's modular, CAIP-2 multi-chain core as it expands.
Fanfare is organized around three product pillars — each a single paid call that composes live data into a decision. The raw per-sport endpoints underneath power them all.
Game-day & trip bundles — tickets, travel, weather, dining in one call.
