Vaunt signals (x402, USDC on Base)

Vaunt runs real money on Hyperliquid and records every outcome. These routes sell the RESULTS — never the rules. Every paid call is one HTTP request with an x402 payment header; any x402 client (@x402/fetch, @coinbase/cdp-sdk/x402, x402-python) does the payment in one round trip. The first call without payment returns HTTP 402 with the price, the input schema and an example output.

When to use which route

You want to know	Route	Price
Is this a buy right now? BUY or NO + buy price + sell price for ASSET, from Vaunt's live real-money strategies	POST /agent/x402/ask {asset}	$0.50
What will a trade on ASSET cost me on Hyperliquid (slippage, fee, latency, depth)?	GET /agent/x402/cost/<ASSET>	$0.001
Did the last two weeks of signals actually pay? (the answer key)	GET /agent/scorecard	free
Evidence for or against MY trade (asset + LONG/SHORT)	POST /agent/x402/evaluate {asset, direction, horizon_h}	$0.50
Same, plus the asset's own trade history, execution cost and liquidity	POST /agent/x402/evidence	$1.00
Just the label (STRONG/MODERATE/WEAK/AGAINST)	POST /agent/x402/preview	$0.001

<ASSET> is a Hyperliquid ticker: BTC ETH SOL HYPE XRP DOGE SUI LINK ARB or a tokenized equity written as xyz-NVDA xyz-TSLA xyz-COIN.

Free, no payment

• GET /agent — manifest with every route and price
• GET /agent/evidence — per-strategy live record (n, independent days, mean, win, hold)
• GET /agent/sample — ten closed trades with context
• GET /agent/venues — execution quality per venue class
• GET /agent/scorecard — the answer key: every position the live routes showed in the last 14 days with its outcome, plus the weekly and per-lane record. Free so it can be checked, not trusted.

Reading the answer

• support: STRONG / MODERATE / WEAK / AGAINST / UNKNOWN — the basis is in basis[].
• cell_evidence.verdict: VALIDATED needs 20+ independent days and t ≥ 2; UNDECIDED means the record is real but short. Read the label before the rank.
• holding_now.yes: Vaunt's own money is in it, shown 60 minutes after entry.
• Returns are per trade, net of fees, on notional. Independent days, not rows, are the sample size.

What is never returned

Entry, invalidation, exit geometry, size, or the thresholds that define a cell. If you need those, this is not the product.
