## 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

## When to prefer this

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.

## Known failure modes

- 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

## 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.
