What Each One Does Best
ActOnce Spend Gateway
Who is it for
Developers and teams using AI agents who need controlled spending and approval workflows.
Problem it solves
AI agents often require purchasing power, which can lead to uncontrolled spend and risky merchant choices. Without clear controls, teams struggle to monitor, approve, or restrict transactions, increasing security and compliance concerns.
How it solves it
ActOnce Spend Gateway provides configurable spending controls and an approval workflow, allowing AI agents to request purchases while you set limits, trusted merchants, blocked categories, and review queues. It integrates with MCP-compatible agents and never handles payment credentials, offering a secure, auditable spending layer.
What makes it unique
Unlike generic payment tools, ActOnce Spend Gateway specializes in AI agent spend governance with per-merchant allowlists, category blocks, duplicate request detection, and an approval queue. It provides both a local MIT-licensed gateway and paid hosted dashboards for team-wide visibility and control.
Use cases
- Set per-agent spending limits
- Approve high-value purchases
- Block risky categories
- Enable trusted merchants only
- Flag duplicate requests
- Manage team approvals
MockBase
Who is it for
Frontend teams, QA engineers, and developers who need reachable API endpoints before a real backend exists.
Problem it solves
Front-end and QA teams struggle when backend APIs aren’t ready, causing integration delays and uncertain tests. They need realistic, controllable endpoints to validate flows, error paths, and performance without a live backend.
How it solves it
MockBase provides a hosted mock API server supporting REST, GraphQL, and SOAP, with conditional routing, live request inspection, and sandboxed templates. It lets teams simulate real-world responses, delays, and rate limits to accelerate testing and debugging.
What makes it unique
It combines a hosted, easy-to-use mock server with stateful Redis-backed storage, deterministic and chaotic response capabilities, and a live streaming inspector for every request. It also supports import/export of OpenAPI definitions and record/replay of real APIs, plus granular matching on query params, headers, bodies, and GraphQL/SOAP specifics.
Use cases
- Create mock REST endpoints
- Create mock GraphQL schema
- Simulate conditional responses
- Stream live request inspector
- Import OpenAPI specs
- Record and replay real APIs
