Trade Analyst
Deterministic trading-analysis toolkit — technical, volume, orderbook, ratio and sentiment operations behind x402 micropayments, with a machine-readable trade-analyst persona.
What is Trade Analyst?
A neutral, deterministic trading-analysis backend usable by any agentic AI. It exposes granular tool operations (data fetchers and compute engines for technical indicators, volume, order book, fundamental ratios and price/volume sentiment) for use inside an agent's own reasoning loop, plus a single-call /ta/ask orchestration endpoint that returns a trade-ready brief. Every computed value comes from the deterministic analytics engine; the persona's hard rule is that no LLM arithmetic ever substitutes for it.
Pay per call in USDC, EURC across Base, Arbitrum, Polygon, Avalanche, Ethereum, Robinhood and Arc via the x402 micropayment protocol — no subscriptions, no API keys, no wallets to configure for the caller.
Every agentic AI can GET /persona and adopt the machine-readable persona/SOUL as a temporary role.

data
| Method | Endpoint | Description | Tier |
|---|---|---|---|
POST | /ta/chart | Fetch OHLCV history (timestamps/OHLCV + meta) for a symbol from Yahoo Finance. | basic |
POST | /ta/quote | Fetch fundamentals snapshot (price, EPS, mcap, debt) for ratio context. | basic |
POST | /ta/fx | Fetch FX rates (US 24h) from open.er-api (stamped midnight UTC). | basic |
POST | /ta/crypto_resolve | Resolve a crypto symbol to its CoinGecko id. | basic |
POST | /ta/crypto_chart | Fetch CoinGecko OHLCV (normalized to the same shape as chart) for a coin. | basic |
POST | /ta/crypto_quote | Fetch a live CoinGecko price + 24h change. | basic |
compute
| Method | Endpoint | Description | Tier |
|---|---|---|---|
POST | /ta/indicator | Compute a deterministic technical indicator from an OHLCV envelope (sma/ema/rsi/macd/bollinger/atr/adx/supertrend…). | basic |
POST | /ta/volume | Compute a deterministic volume indicator from an OHLCV envelope (obv/vwap/mfi/ad/volume_ma/cmf). | basic |
POST | /ta/orderbook | Compute order-book metrics from a level-2 snapshot (spread/mid/depth_imbalance/weighted_mid). | basic |
POST | /ta/ratio | Compute a fundamental ratio (pe/eps/ps/pb/ev_ebitda/peg/margins/roe/de). | basic |
POST | /ta/signal | Deterministic technical signal / sentiment from an OHLCV envelope (trend/rsi/macd/breakout/volatility/volume/adx/stoch/sentiment/snapshot). | basic |
POST | /ta/backtest | Deterministic strategy backtest over a caller-supplied OHLCV envelope with a declarative strategy spec and optional cost model. No lookahead: signal on close(t) executes at open(t+1); whole-share accounting; metrics from a daily mark-to-market equity curve. | basic |
POST | /ta/options_brief | Deterministic option-chain analytics from a caller-supplied chain + spot: ATM straddle expected move, optional VIX-1SD cross-check, IV/delta ladder, 16-delta strangle, and a sample iron-condor credit/max-loss/risk-reward. | basic |
validate
| Method | Endpoint | Description | Tier |
|---|---|---|---|
POST | /ta/verify | Cross-verify two independent values (price pct tolerance or value abs tolerance). | basic |
assembly
| Method | Endpoint | Description | Tier |
|---|---|---|---|
POST | /ta/snapshot | One structured packet for a fast trade read: quote + OHLCV + full technical signal(snapshot) + sentiment. | basic |
POST | /ta/ask | One-call trade-ready analysis. DeepSeek orchestrates the deterministic operations and returns a structured brief (snapshot, signals, levels, entry/target/stop, risk, bottom line). | exclusive |
helper
| Method | Endpoint | Description | Tier |
|---|---|---|---|
POST | /ta/sources | List the service's data sources and their reliability ratings. | basic |
POST | /ta/knowledge | Retrieve the service's methodology corpus (determinism contract, verification, sources, output format). | basic |
Workflows
- trade-read — fast trade-ready technical view:
chart -> snapshot -> verify— lead with technicals/sentiment; establish entry/reference, target, stop - technical-deep-dive — full indicator stack on a name:
chart -> indicator -> volume -> signal— batch RSI/MACD/Bollinger + OBV; cross-verify price vs chart close - crypto-scan — crypto technical + price read:
crypto_resolve -> crypto_chart -> crypto_quote -> signal— normalize to same envelope shape as equities - fundamental-context — attach valuation to a technical view:
quote -> ratio -> verify— use for context only — technicals lead - liquidity-read — order-book / depth view:
orderbook -> verify— spread, depth imbalance, weighted mid over N levels - strategy-backtest — validate a trading strategy:
chart -> backtest— fetch OHLCV, define the declarative strategy spec, run backtest, review metrics/trades - options-brief — 0DTE / expiry option-chain analytics:
options_brief— caller supplies the chain; op returns expected move, strangle, iron condor
Data sources
- Yahoo Finance v8 chart — keyless; set a desktop User-Agent
- Yahoo quoteSummary — needs cookie+crumb flow
- open.er-api FX — midnight UTC rates; ~24h staleness
- CoinGecko v3 — keyless; ~10-30 calls/min burst
