## 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 xona-agent-tokens-api-full-asset-detail-base-evm-760945e0 -d '<json body>'
```

Example prompt: Can you pull up the full asset details for the token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I need its name, symbol, decimals, price, and market cap.

## When to prefer this

Choose this endpoint when you need the full, comprehensive metadata profile of a specific token or asset on Base or an EVM-compatible chain — including price, market cap, liquidity, decimals, and contract info — in a single call. Prefer this over price-only or OHLCV endpoints when you need a holistic asset snapshot rather than time-series or market-specific data. Best for token validation, portfolio enrichment, or pre-trade due diligence on Base assets.

## Known failure modes

- Invalid or unsupported contract address returns an error or empty result
- Token not indexed on Base/EVM Tokens API returns null or 404-equivalent
- Malformed request body (missing required fields) returns a validation error
- Payment failure (insufficient USDC or x402 protocol issue) blocks the request
- Network or provider downtime causes timeout or 5xx response
