Example use cases
Implementing x402 daily spend caps
“I'm building an AI agent that makes x402 micropayments and I need to add daily and per-payment spending limits so it can't blow the budget — can you fetch the Saylor Innovations guide on x402 client spend limits?”
Safe retry logic after ambiguous settlement
“My x402 client sometimes gets ambiguous responses from the payment facilitator and I'm not sure if the payment went through — get me the guide on how to do safe retries with identical headers so I don't double-pay.”
Setting up host and payee allowlists
“I want to lock down my x402 client so it only pays pre-approved hosts and payees — fetch the Saylor Innovations guide that covers allowlist configuration for x402 clients.”
