three.ws Publishes on the AWS Builder Center Blog

Our contribution just went live on the official AWS Builder Center Blog.

The article

"How we metered a SaaS product through AWS Marketplace with the AWS SDK for JavaScript v3"

A technical deep-dive covering the full AWS Marketplace SaaS integration:

• ResolveCustomer — validating the registration token on the fulfillment URL.
• MeterUsage / BatchMeterUsage — reporting per-agent and per-inference usage daily through AWS.
• GetEntitlements — checking contract entitlements for tiered feature gating.
• Verified SNS webhooks — handling subscribe-success, unsubscribe-success, and entitlement-updated lifecycle events with signature verification.
• Bridging to an on-chain x402 paywall — routing AWS subscription state into the three.ws x402 agent payment layer.

All of it is open source at github.com/nirholas/three.ws/tree/main/api/aws-marketplace.
