## 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 dapplooker-crypto-token-metadata-list-b178aed3
```

Example prompt: Show me all indexed crypto tokens on the Ethereum chain from DappLooker — give me page 1 and include any available metadata like addresses and ecosystem info.

## When to prefer this

Use this endpoint when you need to discover, enumerate, or validate the full set of crypto tokens tracked by DappLooker on a specific blockchain. It is best for building token registries, validating token addresses, or bootstrapping downstream analytics pipelines. Prefer this over search-based endpoints when you need a complete or paginated list rather than a specific token lookup.

## Known failure modes

- Missing required 'chain' parameter returns a 400 validation error
- Invalid or unsupported chain identifier returns empty results or 404
- Invalid API key returns 401 unauthorized
- Page number out of range returns empty list or error
- Rate limiting or quota exceeded returns 429 too many requests
- Network timeout or service unavailability returns 5xx error

## How this service works

Fetch a complete list of indexed crypto tokens along with essential metadata. Useful for discovery, enumeration, and validation of active tokens across supported chains and protocols.

## Output

A paginated list of crypto tokens indexed on the specified blockchain chain, including token metadata such as addresses, ecosystem affiliations, and other descriptive fields for each token.
