## 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-ticker-corporate-events-api-b5ad71f4
```

Example prompt: What are all the corporate events on record for AAPL — including any ticker changes — and what's its SEC CIK and Bloomberg FIGI identifier?

## When to prefer this

Use this endpoint when you need authoritative corporate event history — especially ticker symbol changes, SEC CIK numbers, or Bloomberg FIGI identifiers — for a US-listed stock. Prefer over general company info APIs when you specifically need structured event timelines or cross-referencing identifiers (CIK, FIGI) for a ticker. Ideal for AI agents needing to resolve or track corporate identity changes over time without requiring an API key.

## Known failure modes

- Unknown or invalid ticker symbol returns empty events list or 404
- Ticker for non-US or unlisted company may have no data
- Payment failure (insufficient USDC balance) returns 402 Payment Required
- Malformed ticker parameter returns 400 Bad Request
- Rate limiting or service downtime returns 5xx error

## How this service works

Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.

## Output

A JSON object containing the company name, SEC CIK number, Bloomberg composite FIGI, a list of corporate events (each with a date and type such as ticker_change), and the ticker queried, sourced from x402stock as of a specific timestamp.
