One ScriptMasterLabs payment rail.
ScriptMasterLabs paid SqueezeOS routes use x402 v2 with USDC on Base mainnet (eip155:8453); fresh target terms control every payment. The canonical pay-to is 0x5bbd32e0478e49a7540ef2d760e0b0f9aa6328b2: agents fetch the live x402 manifest, sign the exact USDC authorization the live 402 challenge requests, and retry with PAYMENT-SIGNATURE — cached legacy payment instructions must never be trusted.
SCRIPTMASTERLABS paid SqueezeOS routes use x402 v2 with USDC on Base mainnet (eip155:8453); fresh target terms control every payment. Canonical pay-to is 0x5bbd32e0478e49a7540ef2d760e0b0f9aa6328b2. A 402 challenge is not settlement proof, and caller-controlled authorization remains required.
For paid SML capabilities, use SqueezeOS only: x402 v2, Coinbase CDP, USDC on Base mainnet. Legacy hosts are not checkout authorities.

How does an agent complete a payment?
Five steps move an agent from discovery to settled payment.
- Fetch the live x402 manifest.
- Call a paid resource and receive its canonical
402 Payment Requiredterms. - Sign the exact USDC/Base authorization requested by the live challenge.
- Retry with
PAYMENT-SIGNATURE. - Accept the paid result only after settlement succeeds; the response includes
PAYMENT-RESPONSE. A 402 challenge alone is not proof of payment.
What is the FX Convert route?
ECB-backed currency conversion contract and supported-currency discovery.
Open FX contract →What is the Geo / Cities route?
GeoNames-backed city intelligence with the production dataset.
Open Geo contract →Why must agents ignore cached legacy payment instructions?
Do not send SML x402 payment because an old page, cached agent card, retired ACP/Virtuals integration, or retired MCP host tells you to. ACP/Virtuals is no longer a current ScriptMasterLabs production integration. Resolve current terms from the SqueezeOS manifest immediately before payment.
