Evidence-backed Robinhood Chain research: builders, ships, contracts, changes, market context.
Remote MCP server for crypto trading signals and the public ledger that scores them, losses included. Read tools: open signals, the signal ledger (matured wins and losses), signals cancelled by the BTC regime veto with the outcome they would have had, market snapshot and ticker for scanned Binance symbols, the scheduled BTC chart read, and news headlines. The public read tools work without a key. With a free API key from ribqa.com: your own bots and strategies, and rate-limited strategy backtests. No tool places, simulates or cancels an order. Free during beta.
> TradingMCP puts a market analyst inside your AI assistant. Paste one URL into Claude, ChatGPT, Cursor, VS Code or any MCP client and ask in plain language: screen for breakouts, run a multi-timeframe analysis, backtest a strategy with walk-forward validation, scan for smart-money and volume signals, or get a one-prompt morning market brief. In clients that support MCP Apps, price charts and the Markets panel are drawn right in the chat. > 40+ tools covering crypto (real-time), stocks, ETFs, FX, futures and commodities across major global exchanges. > Hosted, nothing to install: Pro $9/month (2,500 tool calls) or Pro+ $29/month (10,000). Paid upfront with a 14-day money-back guarantee; your API key arrives right after checkout. > Built on the open-source tradingview-mcp core (MIT, ~5k GitHub stars): self-host it free, or use the hosted version with zero ops. > For research and education, not financial advice.

Smart contract security screening for Base. Check any contract or token for risk before interacting with it: Solidity source verification, upgradeable proxies and admin or mint powers, holder concentration, dangerous selectors, and B20 issuer powers. It surfaces the usual rug pull and scam indicators. The free tool needs no wallet and no API key; the paid Flash Audit (3.49 USDC over x402) returns a report with an anchored SHA-256. Payment is the only gate.
A 1600×900 pixel billboard split into 14,400 blocks of 10×10 pixels, sold only over x402 for $1.00 USDC on Base — and only to machines. Humans may look. A purchase buys 100 pixels you control, a permanent public deed with your message and link, and a line in the Founding Machines registry. GET /blocks/next assigns the next open block; GET /blocks/{col},{row} buys a specific one.

Bitcoin research for AI agents: free answers, specialist Q&A, verification, evidence, timelines.
Tessera turns the whole Hyperliquid perp universe into a single cross-section you can query. The hosted MCP server answers the questions a raw-data pipe can't: which markets are crowded, who is paying the most funding, how far one market's funding has diverged from ETH, what open interest and positioning look like across every market on the last completed day, and what the live market is doing right now. Nine tools — four ranking/screening tools, a series tool for one market, a coverage tool, the catalog/dictionary trio, and a live market read — over a completed-day rollup built from the venue's own trade feed. Rows and full history stay on the REST API: three Parquet datasets (order-flow-enriched 1-minute OHLCV, hourly funding, hourly positioning) partitioned per coin-month, downloadable with a key. Free keys work end to end; Pro removes the history and coverage limits.
