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 JSON object containing the requested symbol, interval, computed indicator values (e.g. RSI as a float), provider metadata including data freshness and schema version, and a regulatory notice stating outputs are informational only and not financial advice.
Example use cases
Crypto momentum check before trade
“What's the RSI for ETH on the 4-hour chart right now? I want to know if it's overbought or oversold before I make a move.”
Automated trading signal monitor
“Check the technical indicators for SOL on the 1-day interval and tell me whether the RSI suggests a buy or sell signal.”
Multi-asset indicator comparison
“Get me the RSI values for BTC and ETH both on the 1-hour timeframe so I can compare their momentum right now.”
Technical details
Endpoint
POSThttps://api.excelexi.com/api/v1/technical-analysisWhen to prefer
Choose this endpoint when you need programmatic, agent-consumable financial technical indicator values (especially RSI) for a specific asset symbol and time interval, and you can handle micropayment gating via the x402/USDC flow on Base. Prefer this over scraping charting sites or using heavyweight financial data subscriptions when you need lightweight, per-call pay-as-you-go indicator computation without a monthly commitment.
Side effects
- 402 Payment Required — x402 payment gate active, must submit signed EIP-3009 transferWithAuthorization proof in X-Payment header
- Missing required 'symbol' field returns a 400 Bad Request
- Invalid or unsupported symbol returns an error or empty indicator set
- Stale or unavailable market data may affect indicator accuracy
- Network timeout if upstream data provider is slow
