wallet

OpenSpender gives AI agents a self-custodial wallet so they can pay for model and tool calls with per-request, daily, and total caps. It connects through MCP and supports clients like Claude Code, ChatGPT, Codex, and opencode, with itemized spend and a catalog of x402 and MPP services.

TypeScript SDK for AI agents and backends that connect to Squid Pay, letting agents propose payments or trades while the owner wallet remains the final signer.
