Common questions about connecting and running Moejeaux Nexflow Smf.
What is x402 and why would I use NexFlow for payments?
x402 is a payment standard for blockchain transactions on Base. NexFlow's Smart Meta-Facilitator handles routing, verification, and settlement of these payments programmatically, reducing integration complexity.
How do I authenticate with NexFlow?
Set the NEXFLOW_API_KEY environment variable with your API key (format: nf_live_* for production or nf_test_* for testing). The server defaults to https://api.nexflowapp.app unless you override NEXFLOW_BASE_URL.
Can I use this server in a test environment?
Yes. Use an nf_test_* API key in NEXFLOW_API_KEY to test against the sandbox. Switch to nf_live_* keys for production payments.
What payment operations does this MCP server support?
The server supports routing payments through NexFlow, verifying transaction status, and settling payments on Base. Exact operation details are available in the NexFlow API documentation.
What happens if my API key is invalid or expired?
The server will reject requests with an authentication error. Verify your NEXFLOW_API_KEY is correctly formatted (nf_live_* or nf_test_*) and has not been revoked in your NexFlow dashboard.
