coil.trade/api/board/hold
Per-symbol HOLD-STATE read — is the published trend state behind a name intact? GET /api/board/hold?sym=NVDA (up to 10, comma-separated, one price) returns each name's state, hold strength 0-100, readiness, maturity-late flag, overnight gap-risk grade and its book's regime, with the mechanical rules states flip on. BTC-USD/ETH-USD return the crypto book's IN|CASH daily-close state. Impersonal publication — never your entry or size. ~5-min refresh in market hours. Research, not advice.

On-chain payments
Payment shape (25 most recent sampled): 25 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-10-06: 19 payments. Last indexed day 2026-10-09: 1. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 23 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
