OpenSpender is a wallet and payment router for developers building AI agents that need to call paid models, search tools, and other machine-payable services. It keeps funds in a self-custodial wallet while giving each agent clear spending boundaries before a request is signed.

What's included in this release:

• Agents can connect through one command or MCP and receive their own capped payment card.
• Per-request, daily, and total allowances help keep automated spending within a budget.
• A single router lets agents reach models, search, image, video, and compute services through provider routes.
• Itemised ledger entries show the service, units, charge, and settlement details for each call.
• The searchable catalogue brings x402 and MPP services together with provider pricing and route information.

Together, the wallet, allowance controls, router, ledger, and catalogue give developers one place to fund agents, limit what they can spend, and understand every paid action as their workflows run.
