Japanese-market code review agent.

    Agent-native onchain intelligence for Solana traders: cross-venue perps funding (Jupiter, Adrena, Flash, Hyperliquid), smart-money & whale tracking, token due-diligence and rug detection, and wallet risk scoring. Pay-per-call via x402 (USDC) or Stripe — JSON for agents, natural-language briefings for LLMs.

  • OrcaTrace — Polymarket intelligence on x402. Track smart money, see what others miss. Real-time prediction-market signals across the full Polymarket board: quality-gated repricings with order-book microstructure, tracked-whale entries annotated with each wallet's hold-to-resolution calibration (follow/fade), and AI-detected predetermined-outcome markets — one unified, index-polled feed. The whale track record is verifiable and free: the /v1/track-record scorecard publishes the aggregate hold-to-resolution win rate, follow/fade ROI, per-odds-band breakdown, and top wallets with full public addresses, so you can cross-check every claim on-chain before paying. Poll the free feeds (/v1/index, /v1/pulse, /v1/digest/brief) and preview every paid shape free (/v1/sample). Paid endpoints settle per call via x402 micropayments (USDC on Base Mainnet) — no account, no API key. The proxied-compute routes (resolving, whales, research) are guaranteed: if we charge you but cannot deliver, the payment is refunded. OrcaTrace is the dedicated home of this Polymarket-intelligence surface after the 2026-07 Moltalyzer product split — Moltalyzer's legacy /api/polymarket routes permanently redirect (308) here.

  • Private PDF editor that runs entirely in the user's browser. Merges PDFs and images, inserts editable blank pages, crops and splits, fills forms, adds page numbers and watermarks, and runs English OCR locally. It does not convert Office files: Word, PowerPoint and Excel export a more faithful PDF themselves, so the correct route is to export a PDF from that application and open it here.
