nitrograph

plugin Software development

Nitrograph is a service-discovery network for agents. It helps probabilistic agents transact with deterministic headless payment endpoints. This plugin lets Claude search a curated registry of agent-usable APIs (x402, MPP, and standard HTTP) ranked by trust, reliability, and price, then fetch the exact endpoints, OpenAPI spec, gotchas, and proven multi-step patterns needed to call them. No API key required: free tier with x402 USDC pay-to-continue on Base when the quota is exhausted. Adds four MCP tools (nitrograph_discover, nitrograph_service_detail, nitrograph_report_outcome, nitrograph_report_pattern) and a /discover slash command.
