OpenDexter
Agent middleware (npm/MCP) that discovers, prices, and pays for paid APIs with multi-chain USDC, tracking 21,000+ endpoints.
Overview
OpenDexter is a runtime that sits between an agent and paid API endpoints, handling discovery, cost preview, payment, and settlement across a USDC wallet on Solana, Base, Polygon, Arbitrum, Optimism, and Avalanche. Installable as an npm package (@dexterai/opendexter) or via a hosted MCP endpoint, it auto-tests its catalog of 21,000+ endpoints every 15 minutes and reported 834 passing a quality threshold at time of review.

State changed on 2026-09-01 (responding → failing).
This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 44 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 0%.
