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 agent402-rwa-issuer-detail-lookup-5bea95ed
```

Example prompt: Pull up the RWA issuer details for 'coinbase-ecosystem' — I want to see the full list of tokenized assets they issue, their current market cap, and 24-hour trading volume.

## When to prefer this

Choose this endpoint when you need structured market data (market cap, volume, token list) for a specific known RWA issuer by ID, especially within the Coinbase ecosystem or other indexed issuers. Prefer it over general crypto market APIs when you specifically need tokenized real-world asset issuer context, per-call pay-as-you-go pricing with no API key, or when integrating into an agent workflow that pays over x402/USDC.

## Known failure modes

- Invalid or unknown issuer ID returns an error or empty response
- Rate limiting or payment failure over x402 results in 402 Payment Required
- CoinGecko data source temporarily unavailable causing stale or missing data
- Cached response may lag behind real-time market movements
- Missing required 'id' query parameter causes a 400 Bad Request

## How this service works

One issuer of tokenized real-world assets by id: aggregate tokenized market cap, 24h cap change and 24h volume, plus every token it issues with symbol, name and contract address per platform (e.g. Coinbase's Base-chain tokenized Apple, Nvidia, Meta, Alphabet). Use rwa-issuers for ids. Cached in-process for 5 minutes.

## Output

Returns a JSON object with the issuer's ID, display name, total token count, market cap in USD, 24h volume, 24h market cap change, last updated timestamp, data source (e.g. CoinGecko), fetch timestamp, cache status, and an array of tokenized asset objects each containing token ID, name, symbol, and per-platform contract addresses.
