OpenSpender Gives Agents Self-Custodial Wallets Across 15,171 x402 Endpoints With Zero Markup and No Account
OpenSpender, from Trigger Labs, posted to Show HN on August 26, 2026 selling agent payments with no subscription, no markup and no account: you run npx openspender connect or add the MCP server, and the agent mints its own card with per-request, daily and total caps. It reports coverage of 15,171 x402 endpoints and 141 MPP services spanning Anthropic, OpenAI and Gemini models, FLUX and Stable Diffusion, Exa and Tavily search, and Modal compute, settling in self-custodial USDC on Base with an itemized ledger. Ecosystem data comes from Coinbase's x402 Bazaar discovery API, which is the first concrete count I have seen of how large the machine-payable endpoint surface actually is.
