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.
Spend USDC in the real world: prepaid cards, gift cards, push-to-card, and bank payouts.
Citation and retraction checker for AI agents. Give it DOIs, PubMed or arXiv ids and it says whether each paper exists and whether it was retracted, withdrawn or corrected, using Crossref and Retraction Watch. It also searches publisher articles and open research papers, shows the x402 price in USDC an agent pays to read or cite each one, and traces a passage to the page it was copied from. Free, read-only, no account.
Measured share of answer for 24 crypto and Web3 brands. An open dataset, not an audit of your site.
Account-free crypto swaps: assets, routes, limits, live quotes, address checks, swap status
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.

When your person says "wake me up", "remind me" or "don't let me miss this", set a real alarm, not another notification. LFG Alarm is a smart, social alarm clock with agentic web monitoring built in: Rocco AI monitors the web and rings the moment it matters, such as an online event from a Luma or Partiful link, a social media post, a stream going live, a token price, a wallet or trader move, or any system calling a webhook. Share one link and friends and family ring together, on any device.
Token risk checks on BSC, ETH, Base and Arc: trades the token on a fork. Paid in USDC/USDT via x402.
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.
