Data Endpoints - $0.001 per Call

Endpoint	Returns
`GET /v1/prices?symbols=BTC,ETH`	Two labeled venues per symbol: Coinbase exchange spot with 24h stats, and the gTrade leg `{ gains: { pairIndex, mark, index } }`. `mark` is what fills on Gains; `index` is the oracle spot liquidations use. The cross-venue spread is real, tradeable divergence. Covers Gains-listed symbols Coinbase does not carry.
`GET /v1/crowd?symbols=BTC,ETH`	Live gTrade crowd positioning: long vs short split in percent and USD, both sides, total book, plus `bookSharePct` - each pair's share of the whole Gains open book. 90 percent long on a pair holding 4 percent of the venue's money is a very different signal than 90 percent long on a rounding error.
`GET /v1/signals?symbols=ETH,BTC`	Multi-indicator TA bundle - RSI, MACD, Bollinger, VWAP, trend, candlestick pattern - reduced to a directional bias and a conviction score.
`GET /v1/candles?product=ETH-USD&days=30`	OHLCV series.
`GET /v1/stocks`	Coinbase's tokenized U.S. shares on Base (B20): token address, Chainlink feed, live USD price and feed age, share multiplier, and whether each name is minted and tradable. See Tokenized Stocks.
`GET /v1/stocks/price?sym=NVDAc&side=buy&amount=100`	A priced quote for one stock order without the calldata: fill, price per share, premium against the feed, and the pool it would route through.
`GET /v1/swap/price`	Expected output, route, and fees.
`GET /v1/portfolio/{address}`	Token balances with confidence-gated USD valuation. Never a fabricated zero.
`GET /v1/positions/{address}`	Open leveraged perp positions: size, leverage, liquidation price, PnL.
`GET /v1/pending-orders/{address}`	Resting limit and stop orders that have not filled. These hold collateral but are not positions.
`GET /v1/history/{address}`	Closed-trade ledger with entry, exit, and reason: TP, SL, or LIQ.
`GET /v1/stats/{address}`	Trading scorecard: trades, win rate, net USD, gross profit and loss, profit factor, mean R-multiple expectancy, average win and loss, best and worst. The natural input to a risk-sizing agent.
`GET /v1/earn/vaults`	Morpho and Aave vault list with live APY.
`GET /v1/loan/markets`	Floating-rate collateral markets with LLTV, borrow APY, and liquidity.
`GET /v1/loan/fixed`	Every live Morpho Midnight fixed-rate, fixed-term book: marketId, tokens, LLTV, oracle, maturity, and both sides' implied APRs (borrow is best bid, lend is best ask).
`GET /v1/risk/pairs`	Tradeable Gains gTrade pairs with pairIndex, max leverage, and spread.
`GET /v1/ideas/asset/{sym}`	Does one named market have a worthwhile leverage edge right now, and what would be better instead or as a hedge? Direction, range-survival leverage, entry, stop, target, liquidation, edge.

Alpha Endpoints

Endpoint	Price	Returns
`GET /v1/ta/{sym}?gran=900`	$0.005	The complete chart read for one symbol at your timeframe (1m, 5m, 15m, 1H, 1D) - everything the Ozmium chart shows a human, as data.
`GET /v1/ideas/compare?a=ETH&b=BTC`	$0.005	Relative-strength / pairs-trade read. When one leg sits near the top of its recent range and the other near its bottom, the spread is stretched and mean reversion favors long-the-laggard, short-the-leader. Plus each leg's own edge.
`POST /v1/prop/quote`	$0.005	What the prop desk would charge for a given action, and whether the paying wallet qualifies.
`GET /v1/ideas?worthwhileness=strict`	$0.008	The strict shortlist: only the highest-conviction setups sitting on a 52-week extreme, one per direction per category.
`GET /v1/ideas?limit=6`	$0.01	Ranked long and short leverage setups across every category - crypto, forex, energy, metals, indices, stocks. About a year of daily candles reduced to a composite technical signal, ranked by edge times leveraged profit per unit time. Each executable via `/v1/tx/risk/open`.
`GET /v1/arbitrage?target=cbBTC&budget=100&taker=0x..`	$0.01	Ranked, fee-netted cross-asset and DEX-versus-Coinbase arbitrage routes into the target. Each executable via `/v1/tx/swap`.
`GET /v1/ta/scan?symbols=BTC,ETH,SOL`	$0.01	Cross-asset buy/sell dominance in one call for up to eight symbols across 1m, 5m, and 15m.
`GET /v1/loan/analysis/{address}`	$0.01	Borrow-position risk analysis.
`GET /v1/ideas/summary`	$0.01	Market-wide edge aggregate: single best long and best short across all markets, top long and short per category, and breadth counts.
`GET /v1/ideas?worthwhileness=loose&limit=16`	$0.01	The fuller field including marginal plays, for coverage or hedge scanning.
`GET /v1/alpha`	$0.01	The whole alpha stack in one call - arbitrage routes, ranked ideas, and the TA bundle. Cheaper and faster than polling the three separately.

Transaction Builders - $0.01 per Call

Every builder returns ready-to-sign { to, data, value } encoded for Base mainnet. You broadcast from your own wallet. Ozmium never signs.

Basics

POST /v1/tx/swap - spot swap on Base (CDP Trade API plus Permit2).
POST /v1/tx/stocks - buy or sell a Coinbase tokenized share for USDC, $0.001 rather than a cent. Returns the approve plus the Uniswap V3 swap, with the fill, the Chainlink premium, and the pool depth beside them. Full recipe: Tokenized Stocks.
POST /v1/tx/send - transfer a token or ETH.
POST /v1/tx/tip - fund the Ozmium prop desk. No return promised.
POST /v1/tx/burn - burn OZ to the dead address and rank on the onchain burn ladder.

Earn

POST /v1/tx/earn/deposit, /v1/tx/earn/withdraw - ERC-4626 Morpho vault supply and redeem.
POST /v1/tx/earn/aave/supply, /v1/tx/earn/aave/withdraw - Aave supply and withdraw.

Borrow

POST /v1/tx/loan/supply-collateral, /borrow, /repay, /withdraw-collateral - the Morpho Blue floating-rate lifecycle.
POST /v1/tx/fixed/supply-collateral, /borrow, /repay, /withdraw-collateral - Morpho Midnight fixed rate. The borrow builder quotes the live bid book for your target and encodes the takes in order, clamped by a slippage-guarded worst price. The rate locks at execution to the market maturity.

Leverage

POST /v1/tx/risk/open, /v1/tx/risk/close, /v1/tx/risk/modify - Gains gTrade perps with USDC collateral, up to 200x, with exact scaling handled for you: leverage x1e3, prices x1e10, USDC 6dp, slippage x1e3. modify takes action: tp | sl | leverage and adjusts an open position without closing it. A leverage decrease auto-prepends the USDC approve for the collateral top-up.
POST /v1/tx/avantis/open, /v1/tx/avantis/close, /v1/tx/avantis/cancel-limit, /v1/tx/avantis/update-limit - Avantis perps to 500x across crypto, forex, metals and indices. open takes market | limit | stop-limit with optional take-profit and stop-loss, and prepends the USDC approve when the wallet's allowance is short; close is full or partial by collateral. Calldata is built by the venue and verified here (right chain, right contract, a known selector) before you are handed it.
POST /v1/tx/avantis/delegate - authorize (or revoke) an address to sign Avantis intents for a trader. A contract wallet needs this before it can use tpsl: the venue verifies an intent with a plain 65-byte ecrecover and accepts the signer only if it is the trader itself or a registered, unexpired delegate - there is no ERC-1271 path. A delegate can place trades and other trade actions on the trader's behalf (never withdrawals) until expiry, so send it from the trader account and keep the window short.
POST /v1/tx/avantis/tpsl returns an EIP-712 intent, not calldata - Avantis v2 has no on-chain updateTpAndSl, so an open position's take-profit and stop-loss are a payload the owner SIGNS and the venue's operator executes. Sign it and PUT it where the response says, or hand it back to POST /v1/tx/avantis/tpsl/submit ($0.001) and we relay it. Both legs always ride together: pass the current value for the leg you are keeping. On a resting order, use update-limit instead - that one is an ordinary transaction.

Liquidity

POST /v1/tx/lp/aero/add, /v1/tx/lp/aero/remove - Aerodrome vAMM OZ/USDC, with ERC-20 approves for both sides prepended when the live allowance is short.
POST /v1/tx/lp/uni/add, /v1/tx/lp/uni/remove - Uniswap v3 OZ/WETH 1 percent pool at full range, bundled multicall, ETH auto-wrapped and excess refunded. On remove, liquidity: 0 collects fees only - that is the claim path.

Prop Desk

Endpoint	Price	Notes
`POST /v1/prop/quote`	$0.005	OZ cost, match factor, and eligibility. Needs `actionId` plus that action's parameters.
`POST /v1/prop/execute`	$0.01	Runs the action. Needs `actionId`, parameters, and `payTxHash` (agents) or `burnTxHash` (humans).

The x402 fee does not authorize a prop action. See Prop.

Free

Endpoint	Returns
`GET /v1`	The full catalog and live prices
`GET /v1/referrals/{wallet}`	Your referral points and standing
`GET /v1/oz-credit/{wallet}`	Your prepaid OZ credit balance and the rail's full terms

Paying Half

Every price on this page is the USDC price. Prepaid OZ credit covers the same calls at half of it and is exempt from congestion surge. See the credit rail.
