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 computed technical indicator values (e.g. RSI, MACD, EMA, ATR, Bollinger Bands) for the requested asset and parameters, along with a regulatory_notice field set to 'information_only_not_financial_advice'. Responses are informational and do not constitute financial advice.
Example use cases
Momentum check before trade entry
“What's the RSI and moving average convergence for ETH right now? I want to know if it's overbought before I enter a position.”
Volatility analysis for options trading
“Calculate the Average True Range and Bollinger Band width for AAPL over the last 30 days — I need to gauge volatility before picking my options strike.”
Automated trading signal screening
“Run the MACD and stochastic oscillator on SPY for the past 50 days and tell me whether the indicators suggest a bullish or bearish crossover is forming.”
Technical details
Endpoint
POSThttps://api.excelexi.com/api/v1/askWhen to prefer
Choose this endpoint when you need on-demand computation of financial technical indicators (RSI, MACD, EMA, ATR, Bollinger Bands, etc.) for equities or crypto assets and are operating in an x402 micropayment-enabled agent environment on Base/USDC. Prefer this over scraping financial data sites or using generalist LLM knowledge when you need precise, structured, up-to-date indicator values with a clear informational disclaimer.
Side effects
- 402 Payment Required — x402 payment gate active; must submit signed EIP-3009 transferWithAuthorization proof in X-Payment header and retry
- Invalid asset symbol or unsupported ticker — endpoint returns an error if the queried instrument is not supported
- Malformed request body — missing required indicator type or asset parameters results in 400 error
- Insufficient USDC balance for micropayment — payment authorization fails
- Network timeout or upstream data unavailability for the requested time range
