Paid ($0.05 via x402 in USDC on Base, Solana, Monad, Polygon, Arbitrum, Avalanche, Algorand or Stellar, in RLUSD on the XRP Ledger, or in USD₮0 on X Layer), once for 7 days: instead of calling ichimoku_signal again and again, an alert whenever the Ichimoku Cloud signal of a crypto pair turns bullish, bearish or neutral on the timeframe you pick (15m, 30m, 1h, 2h, 4h, 6h, 8h, 12h, 1d, 3d, 1w; checked every 5 minutes). Delivery: "telegram": true gives a t.me link in the answer; your owner opens it once and presses Start, and every turn is then a Telegram message with the price, the plan in the new direction (entry, stop, two targets with risk/reward) and the nearest support and resistance; /levels in that chat shows the levels and targets at any time. And/or webhook_url (https): a POST signed with HMAC-SHA256 on every turn. "on" limits it to one direction (default any). Same as POST /watch. Keep the returned id and secret: status and cancel are free at GET/DELETE /watch/{id} with header X-Watch-Secret. Invalid input (pair, timeframe, webhook) is rejected before payment. Signals from price history, not trade advice.
