OpenSpender Client Onboarding Sprint (5-7 days)

A delivery playbook for agencies to deploy AI agents with self-custodial wallets and hard spending caps, turning OpenSpender's infrastructure into a managed service for clients who need cost-controlled API access.

Prerequisites
  • Client holds USDC on Base and is comfortable with self-custody
  • Agency team has basic familiarity with MCP and x402/MPP payment standards
  • Client's AI agent workflow is defined (e.g., scheduling, SMS, or lookup API)
  • Access to OpenSpender admin panel and ability to create allowance tokens
  • Client budget for API spend is confirmed and documented
Execution Timeline
  • 1.Create a self-custodial wallet on Base and fund it with USDC
  • 2.Review OpenSpender's MCP integration docs and x402/MPP endpoints
  • 3.Define client's per-request, daily, and total spending caps based on budget
  • 1.Connect client's AI agent to OpenSpender via MCP
  • 2.Set up allowance tokens with the agreed caps and route to provider endpoints (e.g., Anthropic, OpenAI)
  • 3.Test a single API call to verify wallet settlement and cap enforcement
  • 1.Integrate the agent with the client's chosen paid API (e.g., scheduling or SMS)
  • 2.Configure alert thresholds for approaching daily limits
  • 3.Run a full workflow test with multiple requests to confirm per-request caps hold
  • 1.Document the wallet custody process and security practices for the client
  • 2.Set up a monitoring dashboard for spend tracking and audit trails
  • 3.Train client staff on how to revoke agent access instantly if needed
  • 1.Finalize the service agreement including API spend limits and overage policies
  • 2.Deliver a handoff guide covering wallet management and cap adjustments
  • 3.Schedule a post-launch review to assess actual usage against caps
OpenSpender charges usage-based fees per API call, with MPP pricing at $0.003 to $0.04 per image for Tempo, so a typical client deployment might see monthly API costs ranging from $50 to $500 depending on call volume.5-7 days
ROI Logic

Agencies can charge a setup fee of $1,800 for a 16-hour deployment, while OpenSpender's per-call fees are passed through to the client, leaving the agency with a healthy margin. The usage-based pricing means the agency's cost is proportional to client usage, so the margin stays consistent even as the client scales.

Deliverables
  • Configured OpenSpender wallet with USDC funding and security checklist
  • Allowance tokens with per-request, daily, and total caps for each agent
  • MCP integration code and configuration files for the client's agent
  • Spend monitoring dashboard and alert setup documentation
  • Client handoff guide covering wallet custody, cap adjustments, and revocation procedures
Definition of Done

The client's AI agent successfully completes a full workflow using OpenSpender's wallet, with all spending caps enforced and the client able to revoke access independently.
