Sentinel Aleph: free crypto signals you can curl, give to your AI agent, or run as a paper bot

A developer named Ahmet has launched Sentinel Aleph, a free crypto market scanner in open beta that monitors 570+ Binance spot and futures markets on the 4-hour chart and publishes trade signals with entry, stop and target levels alongside a public ledger of every outcome, net of fees. The service exposes roughly 40 public API routes callable via curl and an MCP server with 16 tools that lets Claude, Cursor or other MCP clients query open signals, track records and market snapshots, though it places no orders. The accompanying Rust/Tauri desktop app Aleph Edge, whose source is on GitHub, trades on the signals, and the project states plainly that no edge after costs is established yet.

I'm Ahmet. For the past two to three years I've been building a crypto market scanner for myself in Switzerland, because I was tired of signal groups that only ever post screenshots of their wins. It's now in open beta as Sentinel Aleph , and it's free. This post is about what you, as a developer, can do with it in the next five minutes. In one sentence: Sentinel Aleph scans 570+ Binance spot and futures markets on the 4-hour chart, publishes trade signals with entry, stop and targets, and records every outcome wins, losses, break-evens and the setups it rejected on a public ledger, net of fees. No account, no key: curl -s "https://ribqa.com/api/public/signals/pending?limit=3" Each signal comes back with its market, direction, entry, stop, take-profit levels and the engines that agreed on it: POLUSDT spot long entry 0.10635 stop 0.10156 tp1 0.11040 KGENUSDT futures long entry 0.1478 stop 0.13654 tp1 0.15590 SOONUSDT futures long entry 0.31 stop 0.28870 tp1 0.31903 There are about 40 public routes in total: the monthly ledger, vetoed signals, a scheduled BTC chart read, news. The API Center https://ribqa.com/api-center lists every route with its access level and a copyable curl. Sentinel Aleph runs an MCP server, so Claude, Cursor or any MCP client can query it directly: claude mcp add --transport http sentinel-aleph https://ribqa.com/api/v1/mcp That gives your agent 16 tools. Seven of them answer without a key: open signals, the ledger's track record, vetoed signals, market snapshots, tickers, the BTC chart read and news. The other nine work on your own account with a free API key add it as an Authorization: Bearer header : save and edit strategies, run backtests, list your bots. Then you can ask things like: "Which futures signals are open right now, and how did last month's signals do after fees?" It can't trade: the MCP server places no orders of any kind. Setup, tool list and JSON config are on the MCP page https://ribqa.com/mcp . Aleph Edge https://ribqa.com/edge is the desktop app that trades on these signals. It's built in Rust with Tauri 2 and the source is on GitHub https://github.com/sentinelaleph/AlephEdge . Most signal services show you a win rate. We show the whole book: every published signal and how it ended, settled against real Binance candles, after fees, with the sample size next to every figure. Ratios only count signals at least 96 hours old, because losers take longer to settle than winners and early numbers look better than they are. That honesty cuts both ways. Here is the ledger by month, without the BTC-veto closes: | month | trades | net after fees | |---|---|---| | August 2026 | 498 | +62.23 pts | | September 2026 | 460 | +12.39 pts | | October 2026 running | 275 | +261.01 pts | Points are sums of per-trade percentages, not an account return. Counting the positions the BTC veto closed early, August and September turn negative. So the site says it plainly: no edge after costs is established yet. You can see every month in full https://ribqa.com/reports and judge for yourself. Everything is free during the beta. I'd really like to hear from you: Market research, not financial advice.
