Start Project Discovery

Turn an approved x402 plan into a working, tested, machine-payable offer.

Implementation of a defined x402 offer

This service implements one clearly scoped x402-ready offer: the access model, the payment path, the technical wiring, and the verification needed to confirm it behaves correctly before launch.

Who It's For

  • Businesses that have completed readiness work and know what they want to sell
  • Owners of an existing API, dataset, tool, or service ready to gate access
  • Teams that want implementation handled rather than doing it in-house

What Is Included

  • Confirmation of the offer, access model, and pricing approach
  • Payment architecture setup guidance and wiring
  • Implementation of one defined machine-payable access path
  • Testing and verification of the payment and access flow
  • Basic monitoring and troubleshooting guidance
  • Launch preparation checklist
  • Documentation and handoff

What Is Not Included

  • Multiple unrelated endpoints or offers
  • A wallet funded or managed by StorefrontSignal
  • Ongoing operation, monitoring, or support after handoff
  • Directory or marketplace acceptance

Customer Responsibilities

Access to the systems being modified, decision-making on pricing and access rules, and availability for verification testing.

How Final Pricing Is Determined

The figure above is a starting point, not a quote. Final scope and price are confirmed during your free Project Discovery consultation, before any work begins, and depend on technical factors including:

  • Number and complexity of integrations
  • Infrastructure and hosting requirements
  • Authentication and access-control requirements
  • API design, endpoints, and data handling
  • Agent behavior, permissions, and approval boundaries
  • Payment architecture and settlement requirements
  • Monitoring, logging, and alerting needs
  • Deployment environment and release process
  • Ongoing support and maintenance expectations

Third-Party Costs

Hosting, domains, API usage, software subscriptions, infrastructure, wallet funding, and other third-party provider charges remain the customer's responsibility and are separate from this engagement unless explicitly included in writing.

What We Do Not Promise

  • No guarantee of revenue, traffic, adoption, or marketplace acceptance
  • No guarantee that any third party, agent, or crawler will pay for access
  • No guarantee of specific technical compatibility until scope is confirmed
  • No legal, tax, accounting, security, or financial advice
