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.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.
Install — not run by us — no falsifiable install+entry probe from deploy_spec
Runtime: Node.js (npx setup) or hosted MCP
npx @dexterai/opendexter setup Setup command creates a local wallet and wires OpenDexter into Claude Code, Cursor, Codex, Windsurf, Gemini CLI, or VS Code; tools: x402_wallet, x402_search, x402_check, x402_fetch, x402_access, x402_settings
You supply: Setup creates a wallet on your machine (local key custody risk); hosted mode instead uses a funded session wallet
MCP invocation: hosted URL: open.dexter.cash/mcp (point any MCP client at it)

State changed on 2026-09-12 (unreachable from our probe → failing), 2026-09-23 (failing → unreachable from our probe), 2026-10-19 (unreachable from our probe → failing), 2026-10-20 (failing → unreachable from our probe).
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. 39 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. Every one of them passed, so the rate covers them too.
Last 30 days — to 2026-10-22, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
