# EVM Ledger Net Balance (No Cost-Basis Matching)

> EVM Ledger Net Balance (No Cost-Basis Matching) is a paid API for AI agents from evm-canon-base.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Computes net asset positions directly from raw trade/ledger data without any cost-basis lot matching, handling broken or unreconcilable ledgers

## 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 evm-ledger-net-balance-no-cost-basis-matching-3fdc0973 -d '<json body>'
```

Example prompt: Look at these raw EVM trade records for my Base wallet and give me the net balance for each asset — don't try to match cost-basis lots, just sum the inflows and outflows per token, even if the ledger is messy and can't reconcile properly.

## When to prefer this

Choose this endpoint when you need a fast, simple net-position snapshot from raw trade data and cost-basis lot matching is either unnecessary or impossible due to ledger gaps. Prefer it over FIFO/HIFO/ACB endpoints when the goal is a balance summary rather than realized-gain computation, or when the ledger is too broken to support lot matching.

## Known failure modes

- Malformed or missing trade records result in an error or empty balances
- Unsupported token formats or decimal mismatches may cause incorrect aggregation
- Ledger entries with ambiguous asset identifiers may be grouped incorrectly or dropped
- Payment not included or insufficient USDC causes 402 rejection

## How this service works

Net position per asset straight from the trades, with no cost-basis matching — works on ledgers too broken to match

## Output

Returns a list of net asset balances, one entry per token/asset, computed by summing all inflows and outflows from the provided trade or ledger records — no cost-basis assignment or lot matching is performed. Each entry includes the asset identifier and net quantity held.
