## 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 x402-bazaar-erc-20-portfolio-net-worth-e4afde6e -d '<json body>'
```

Example prompt: What are all the ERC-20 tokens held by 0xAbC123...def on Base, and what is the total portfolio worth in USD right now — spam filtered and sorted by value?

## When to prefer this

Use this endpoint when you need accurate, spam-filtered USD valuations of all ERC-20 holdings on Base, especially when stablecoins and long-tail tokens must be priced correctly. Prefer it over generic balance endpoints that lack USD conversion or spam filtering.

## Known failure modes

- 402 Payment Required — must pay $0.01 USDC on Base to the specified address and retry
- Invalid or malformed wallet address returns an error
- Address with no ERC-20 tokens returns an empty portfolio
- Covalent pricing unavailable for a token may result in missing USD values
- Network or relay timeout returns 5xx error

## How this service works

Complete ERC-20 portfolio for a Base address with accurate USD values from Covalent (handles stablecoins & long-tail tokens). Spam-filtered, sorted by value, with a total. The reliable portfolio endpoint. Paid via x402: $0.01 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.

## Output

A sorted list of ERC-20 token holdings for the given Base address, each with token symbol, balance, and USD value derived from Covalent pricing (including stablecoins and long-tail tokens), spam filtered, plus a total USD portfolio net worth.
