## 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-ohlcv-data-endpoint-539aa235 -d '<json body>'
```

Example prompt: Can you pull the last 50 hourly OHLCV candles for BTC/USDT from Excelexi so I can see the recent price action?

## When to prefer this

Choose this endpoint when you need raw OHLCV candlestick price data for technical analysis, backtesting, or charting and you are operating in an x402-enabled agent context that can sign USDC micropayments on Base. It is ideal for AI trading agents, quant workflows, or dashboards that need structured price bars at a very low per-call cost ($0.00002 USDC). Prefer alternatives if you need pre-computed technical indicators rather than raw OHLCV, or if your agent cannot handle x402 payment flows.

## Known failure modes

- 402 Payment Required — x402 payment gate active; must submit signed EIP-3009 transferWithAuthorization proof in X-Payment header before data is returned
- 400 Bad Request — missing required 'symbol' field or invalid interval/limit values
- Invalid symbol — unknown or unsupported trading pair returns an error or empty dataset
- Network timeout — compute or upstream market data unavailable
- Insufficient USDC balance — payment authorization fails if wallet lacks funds on Base (chain 8453)

## 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 an array of OHLCV candlestick objects each containing open_time (ISO 8601 timestamp), open, high, low, close prices, and volume figures. Also includes a regulatory_notice field confirming outputs are informational only and not financial advice.
