x402-everything

@kitty4d

Use when evaluating whether a new idea fits the x402 HTTP 402 payment protocol - pay-per-call APIs, AI agent commerce, MCP paid tools, content paywalls, micropayments, machine-to-machine payments, IoT/hardware payments, agent-to-agent settlement, or assessing protocol limits like EIP-3009, USDC-only assets, the "exact" scheme, facilitator choice, network selection, or v1->v2 changes. Vendor-neutral; not tied to any specific SDK, chain, or facilitator vendor.
