Pricing at a glance
The OMNIGATE fee is 0.005 USDC per settlement. The fee leg is optional. A standard payment with no fee leg settles with the fee waived inside a daily budget of 500 settlements across all payees and 100 per payee, counted on the UTC day. Past the budget, a fee-less payment is refused until the next UTC day, and a payment carrying the 0.005 USDC leg always works — the fee is collected after the merchant leg. ScriptMasterLabs' own services are exempt. The merchant is always paid in full, directly to their wallet: OMNIGATE takes no custody of merchant funds.
Networks: Base (eip155:8453) and Arc (eip155:5042). Schemes: x402 v2 exact on both, plus x402 v1 on Base. Signer: 0x290906966f830bF6d0e9E370CB6Ef28b656c74BE. Terms verified live from OMNIGATE's /supported response on November 9, 2026.
