## 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 x402stock-concept-ticker-lookup-9f75189d
```

Example prompt: Can you look up what NVDA is — give me the concept overview for that ticker, like what the company does and what kind of instrument it is?

## When to prefer this

Use this endpoint when you need a conceptual overview or background description of a ticker — what it is, what entity it represents, and its asset class — rather than live price data, historical candles, or fundamental financials. Ideal for enriching agent context before making trading decisions or explaining an instrument to a user.

## Known failure modes

- Unknown or invalid ticker symbol returns an error or empty result
- Ticker format mismatch (e.g. wrong exchange suffix) may yield no data
- Payment failure via x402/USDC results in 402 response and no data returned
- Rate limits or transient upstream errors may cause 5xx responses

## How this service works

Market and economic data for AI agents — US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities (crude, natural gas, gasoline), US and global macro (Fed funds, CPI/PCE, jobs, GDP, Treasury debt & yields, World Bank indicators), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 or MPP. This server is a pay-per-use, transparent proxy in front of x402stock's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. The complete verified paid surface is listed at /openapi.json, the source of truth for available operations. Each operation here carries its live price in x-payment-info. Use the operations and details here when they meet your needs. Filtered specs contain only matching operations; if you cannot find what you need here, use search or the service catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge, reserved for agents claimed by a human with a verified email.

## Output

Conceptual and descriptive metadata about the requested ticker, including what the instrument is, the entity behind it, its asset class or category, and other contextual information that helps an agent or user understand what the ticker represents.
