## 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 402-com-tr-erc-20-wallet-portfolio-base-658d4afd
```

Example prompt: What's the full ERC-20 portfolio and total USD net worth for Base wallet 0x1234abcd...? Show me all tokens sorted by value, spam filtered.

## When to prefer this

Use this endpoint when you need a complete, USD-valued ERC-20 token breakdown for a Base network wallet address. It is specifically optimized for Base chain, uses Covalent for accurate pricing of both stablecoins and long-tail tokens, and applies spam filtering — making it more reliable than generic balance checkers. Prefer this over raw RPC calls or generic multi-chain portfolio APIs when Base-specific accuracy and spam filtering matter.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Address with no ERC-20 holdings returns an empty portfolio with $0 total
- Covalent pricing unavailable for extremely obscure tokens may result in $0 value for those tokens
- Rate limiting or payment failure returns 402 or 429 error
- Non-Base chain addresses may return empty or incorrect results

## How this service works

Complete token portfolio for a Base address with USD values: every ERC-20 the wallet holds, priced from live DEX liquidity, plus native ETH — sorted by value with a total. Holdings nobody quotes are listed and counted separately rather than silently valued at zero.

## Output

A spam-filtered list of ERC-20 tokens held by the queried Base wallet, each with token symbol, balance, and accurate USD value (sourced from Covalent, handling stablecoins and long-tail tokens), sorted descending by value, plus an aggregated total USD net worth.
