Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 quotient-asset-directory-9729fde0
```

Example prompt: Pull the full Quotient asset directory for me — I need the stable UUIDs and assetKey values for all crypto assets so I can map them to prediction markets.

## When to prefer this

Use this endpoint when you need stable, canonical asset identifiers (UUIDs, assetKeys) to use in downstream Quotient API calls, or when building a reference directory of tracked assets. Prefer this over the asset search endpoint when you want the full catalog rather than semantic search results, and when you do not need forecast, probability, or venue-price data. Use filters for platform or asset_type to narrow results efficiently.

## Known failure modes

- Invalid platform or asset_type filter value returns empty results or a 400 error
- Service unavailable on Render cold start causing slow or failed response
- Network timeout if the catalog is large and the Render instance is spinning up
- 402 Payment Required if x402 payment header is missing or USDC balance is insufficient

## How this service works

Browse Quotient's canonical underlying-asset directory without forecast or venue-price data. Use this for stable Asset UUIDs and assetKey values, names, tickers, aliases, exact platform identifiers, and active directly linked market counts. The complete filtered catalog returns in one response; use asset search when the user needs linked prediction-market intelligence.

## Output

A complete filtered catalog of assets tracked by Quotient, returned in a single response. Each asset entry includes a stable UUID, assetKey, canonical name, ticker symbol, known aliases, exact platform-specific identifiers, and a count of active directly linked prediction markets. No forecast or venue-price data is included.
