# Excelexi Technical Analysis API

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability excelexi-technical-analysis-api-167836f6 -d '<json body>'
```

Example prompt: What's the current RSI for BTC on the 1-hour interval? Pull the technical analysis indicators from Excelexi.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
