  "textContent": "I built PayGraph, an open-source Python SDK and CLI that sits between AI agents and payment rails.\n\nEvery payment tool call runs through a policy (daily budgets, transactions cap, vendor allowlist) making autonomous payments safe for AI agents.\n\nI built it because I kept writing the same wrapper around payment tools in every agent I shipped.\n\nIt worlds with x402, Stripe issuing and Stripe shared payment tokens and integrates with LangGraph and CrewAI. There is a mock gateway so you can try it without spending real money.\n\n  * pip install paygraph\n\n\n\nIts early (first commit wasn’t even one month ago) and I’m unsure about the following (would appreciate your take in the comments):\n\n  * Two concurrent requests can both pass the check before either commits, and nothing stops you from going over. Which becomes a serious problem for multi-agents fleet. Not sure if i should move the budget into a shared ledger with CAS, or if there’s a lighter primitive I’m missing.\n\n  * If the LLM retries mint_virtual_card with the same argos (which happens when the harness loses response) the gateway mints a second card. I haven’t added a dedup key because I can’t decide where it should live: the agent framework, the wallet or the gateway? Each of these has its own tradeoffs\n\n\n",
