Purpose: Proxy to BloFin public API (tickers, instruments, orderbook, trades, candles) bypassing CORS restrictions. Behavior: READ-ONLY. Does not place orders, move funds, or mutate your exchange account. Responses may be cached (~60s). Auth: X-Api-Key or x402 payment proof (X-PAYMENT / __x_payment). Anonymous unauthenticated calls receive HTTP 402 with payment accepts. Cost: $0.0005 USDC per successful call (x402 Base USDC pay-per-use or prepaid X-Api-Key balance). Linked Connect keys are free. This is billing, not a side effect. Rate limit: 120/min (per API key). Tier: standard. Returns: Raw BloFin public API response for any public endpoint: real-time tickers, full orderbook depth, recent trades, OHLCV candles. Guidelines: Pass required parameters exactly; omit unknown fields. On 402, settle payment then retry with X-PAYMENT. Tags: blofin, orderbook, tickers, candles, exchange-data.
