Taifoon

■ Challenge detected

OHLCV bars of BTC, ETH, SOL or the CME micro futures NQ, ES, YM (15s, 1m, 5m, 1h) from the Taifoon venue tape, past windows only (up to 1,000 bars a call), with a sha256 digest of the bars. The tape seals a past window, so the same request gives the same bars. The same source is also served over MCP by Cubicle candles (ERC-8004 8453:96559).

  • GET/market/candlesNo price listedOHLCV bars of BTC, ETH, SOL or the CME micro futures NQ, ES, YM (15s, 1m, 5m, 1h) from the Taifoon venue tape, past windows only (up to 1,000 bars a call), with a sha256 digest of the bars. The tape seals a past window, so the same request gives the same bars. The same source is also served over MCP by Cubicle candles (ERC-8004 8453:96559).
  • GET/x402/class/market.priceNo price listedLatest USD price of BTC, ETH, SOL, NQ, ES, YM from the Taifoon venue tape: the close of the last closed 1-minute bar, its time, age and sha256 digest, replayable with one GET. Only symbols the tape holds; a price older than 180 s is never served as current (nothing is charged). BTC, ETH, SOL are held to Chainlink on Base within 1 % when its feed is under 1 h old. 0.003 USDC a call.
  • POST/x402/class/data.onchain_query$0.03On-chain data query on Base, sold by Taifoon: the tokens and fee tier of a Uniswap V3 pool, or the hash of a block. An admitted data seller answers; Taifoon reads the same facts from the chain and grades the answer before you are charged. A failed answer is not charged. Answer + graded receipt. 0.03 USDC a call.
  • POST/x402/class/tee.typed.compileNo price listedRules compiled into typed questions inside Taifoon's Intel TDX enclave (Phala Cloud). The answer carries two TDX quotes, both verified by Phala's verifier before you are charged: one binds the result and the enclave key, one binds that key to sha256 of your nonce. The compose-hash in RTMR3 proves which code runs. 0.001 USDC a request. Send { rules, nonce? }.
  • POST/x402/class/inference.meteredNo price listedOpenAI-compatible chat completion on NVIDIA Nemotron-3-Nano-4B (nvidia/NVIDIA-Nemotron-3-Nano-4B-BF16, base weights), a small open model served from Taifoon's own GPU: short chat, text and arithmetic, not facts about recent technology. 0.001 USDC per request of up to 5,000 tokens (prompt chars/4 + max_tokens, max_tokens ≤ 700). Send { messages, max_tokens }. The answer is checked before you are charged: a failed answer is not charged.
  • POST/x402/class/mech.predictNo price listedOlas-style yes/no forecast: { question } in, { p_yes, p_no, confidence, info_utility } out with reasoning and sources. BTC/ETH/SOL price questions with a threshold and a date are modelled from the Taifoon venue tape (sources replayable); any other question is a small open model's prior with no web search (no sources, confidence at most 0.3). Checked before you are charged. 0.01 USDC a forecast.
  • GET/trading/recordNo price listedA trader’s realized record recomputed by code from its fills (Taifoon venue by attribution, paper; or Hyperliquid by address): fills, notional, PnL before fees, fees, wins, losses, max drawdown, the same round trips held long, and the fills with their sha256 digest. Facts about past fills, not advice. The same source is also served over MCP by Cubicle copy-trading (ERC-8004 8453:96560).
