The free 9-part video course, Explore The Coin Daily Research, walks through setup and the full workflow — charts, comparisons, news and using the tools in ChatGPT or Claude: https://www.youtube.com/playlist?list=PLKY7CRxbV8Fc Ask your assistant for a chart and it arrives in the conversation — scrub Bitcoin's week, set an A-to-B range, and see the move in numbers. Pull funding, open interest, liquidations and order-book depth. Catch hourly regime shifts. Compare whole sectors, like DeFi against AI tokens. Follow source-linked news and ticker video coverage, or read the latest published Market Update with its chapters. Every figure is grounded in The Coin Daily's own research pipeline: widgets render exactly what was read, missing readings stay visible gaps, and nothing is invented. Editorial market commentary — not investment advice. No trading, wallets or payments, ever. Sign in with OAuth.

Let your AI agent pay for APIs and data without handing it your money. In ChatGPT, Claude or Grok, the agent finds paid x402 APIs (with each seller's payout record from x402 Doctor) and asks to pay; you approve and sign each payment in your own wallet: MetaMask or Coinbase Wallet (USDC on Base), Phantom (USDC on Solana) or Xaman (RLUSD on the XRP Ledger). Fizzl checks every payment before you sign and every paid answer for hidden instructions. Fizzl never holds your keys. Free to start.

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.
Agent tools for discovery, payment safety, data extraction, and DeFi.

Warden MCP lets AI agents find tokens, quote swaps and trade onchain on Base, BNB Chain, Robinhood Chain, Arc and Solana, within limits you set. Market tools need no credential: list_chains, search_tokens, trending_tokens, price_history, quote_swap and swap_status. Search by name, ticker or contract address, read USD price candles, and price a swap before committing to it, including cross-chain swaps. Wallet tools act for the wallet whose owner connected the agent, by OAuth sign-in or a wk_ key. agent_permissions shows what the agent may do and its daily limits. prepare_swap builds a trade and hands the owner a review link to sign. With request_session the owner turns on hands-free trading in one tap, and execute_swap then trades within the limits they set. swap_status tracks gasless and cross-chain trades. get_wallet shows holdings on every chain. Gasless trading is available on Base, BNB Chain and Robinhood Chain. Built by Warden Protocol, the team behind Warden Token Terminal.
