## 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-financial-technical-indicators-signal-query-e9d81385 -d '<json body>'
```

Example prompt: Can you pull the latest RSI and MACD signals for BTC/USD from Excelexi so I can see whether Bitcoin is currently overbought or in a bullish trend?

## When to prefer this

Choose this endpoint when you need programmatically computed financial technical indicator signals (RSI, MACD, Bollinger Bands, moving averages, etc.) for a specific asset and are comfortable with a USDC micropayment per query. Prefer this over generic market data APIs when you specifically need technical analysis signal computation rather than raw price data or fundamental analysis.

## Known failure modes

- 402 Payment Required — x402 gate active, must submit signed EIP-3009 transferWithAuthorization proof in X-Payment header and retry
- Invalid or unsupported indicator slug — returns error indicating unknown signal type
- Malformed query parameters — returns 400 Bad Request with validation details
- Asset or symbol not found — returns error if the requested ticker or pair is not supported
- Payment amount insufficient — if USDC micropayment does not meet the per-slug price, request is rejected

## 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 and signals for the queried asset, along with a regulatory_notice field set to 'information_only_not_financial_advice'. Responses include the indicator slug, computed numeric values, and signal interpretation metadata.
