## How to call it through Zero

```sh
zero fetch --capability x402stock-exchanges-list-91a524ef
```

Example prompt: Can you give me a list of all supported US stock exchanges with their MIC codes and acronyms so I can figure out which exchange identifier to use for my trading app?

## When to prefer this

Use this endpoint when you need to discover or validate exchange identifiers (MIC codes, acronyms, participant IDs) for US markets before querying stock data by exchange. Prefer this over hardcoding exchange IDs or using generic financial reference databases when working within the x402stock ecosystem.

## Known failure modes

- Payment failure: 402 response if USDC payment via x402 is not provided or insufficient
- Upstream data unavailable: source 'massive' may return stale or empty data
- Rate limiting or provider downtime resulting in 5xx errors
- Malformed response if exchange list is empty or partially populated

## How this service works

Reference list of US equity exchanges and market centers with names, MICs, operating MICs, and SIP participant IDs. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

## Output

A JSON object containing an as_of timestamp, total count of exchanges, data source, and an array of exchange records each with id, MIC code, operating MIC, name, type (exchange/dark pool/etc.), acronym, participant ID, and URL.
