I want my agent to pay for APIs
- If you want straightforward pay-per-request billing with a public facilitator, start with
x402. - If you want HTTP-native payments with a choice between one-off charge and channel-based session payments, start with
MPP.
I want to charge other agents
- Use
Accept x402 Paymentsif you want the simplest integration path today. - Use
MPP Charge Paymentsfor one-off signed authorizations. - Use
MPP Session Paymentsif clients will make repeated requests and you want lower per-request overhead.
I want an agent to control an AGW
- Start with
AGW CLI Overview. - Then follow
Install and Authenticate. - If your host supports MCP, continue to
Run AGW as MCP.
I want my coding agent to understand Abstract docs
- Use
Agent Resourcesfor docs MCP and machine-readable docs formats. - Use
SKILL.MDwhen the agent needs workflows, decision tables, and gotchas instead of raw page text.
