How this service works
**Excelexi** — Financial technical indicators API marketplace. Agent-consumable OpenAPI document for the public Excelexi indicator surface. **x402 Payment**: Indicator compute endpoints require a USDC micropayment on Base (Coinbase L2, chain 8453). When the x402 gate is active, a 402 Payment Required response is returned with a payment challenge. Submit the signed EIP-3009 transferWithAuthorization proof in the `X-Payment` header and retry the request. **Discovery**: `GET /.well-known/x402` returns the current per-slug prices. **Regulatory notice**: All indicator outputs are informational only and do not constitute financial advice. Responses include `regulatory_notice` = `"information_only_not_financial_advice"`.
Output
Returns a time-series array of computed technical indicator values for the requested asset and date range, along with a regulatory_notice field set to 'information_only_not_financial_advice'. Each data point includes a timestamp and the computed indicator output(s) for that period.
Example use cases
Backtest a momentum trading strategy
“Get me 180 days of historical MACD(12,26,9) data for ETH/USD from Excelexi so I can backtest my momentum strategy.”
Volatility analysis for options pricing
“Fetch the last 60 days of historical ATR(14) values for AAPL from Excelexi — I need it for my options premium model.”
Charting historical Bollinger Bands
“Pull Bollinger Band history (20-period, 2 standard deviations) for SOL/USD over the past 30 days from Excelexi so I can plot the squeeze signals.”
Technical details
Endpoint
POSThttps://api.excelexi.com/api/v1/analytics/historyWhen to prefer
Choose this endpoint when you need historical technical indicator computations on demand without managing your own time-series database or indicator library. It is ideal for AI agents doing backtesting, signal research, or chart generation that need pre-computed indicator history rather than raw OHLCV data. Prefer this over raw market data APIs when you need indicator math (RSI, MACD, ATR, Bollinger Bands, etc.) already applied to historical prices. The per-call micropayment model suits low-frequency or exploratory use better than a subscription.
Side effects
- 402 Payment Required — x402 gate active, must submit signed EIP-3009 transferWithAuthorization proof in X-Payment header
- Invalid or unsupported indicator slug — returns 400 or 404
- Asset symbol not found or unsupported — returns 404
- Date range too large or malformed — returns 400
- Insufficient USDC balance for micropayment — payment authorization fails
- Network or compute timeout on complex indicator history — returns 503
