# Delx Commerce — EVM Token Balance Budget Check

> Delx Commerce — EVM Token Balance Budget Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Checks whether a raw EVM token balance is sufficient to cover a required raw amount, returning a pass/fail result with shortfall details.

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 delx-commerce-evm-token-balance-budget-check-b0d2e7ea -d '<json body>'
```

Example prompt: Before submitting this EVM token transfer, check if my available balance of 2500000 raw units is enough to cover the required 1500000 raw units — I need to know if it's sufficient, and if not, by how much I'm short.

## When to prefer this

Use this endpoint when you need a lightweight, privacy-preserving, verifiable computation to check whether an EVM token balance covers a required spend amount before committing to a blockchain transaction. Prefer this over on-chain balance reads when you already have the raw values in memory and need a fast, auditable preflight result with cryptographic evidence of non-retention. It is especially useful for AI agents orchestrating DeFi workflows or on-chain payments that need a trustless sanity check without storing sensitive financial data.

## Known failure modes

- Malformed or non-numeric string values for amount_raw or balance_raw may cause a validation error
- Excessively large strings beyond the 8192 character limit will be rejected
- Missing required fields returns an error response
- Network or payment (x402) issues may prevent the call from completing

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object indicating whether the balance is sufficient (boolean), the required and available amounts in raw units, the shortfall (0 if sufficient), a pass/fail status, and a tamper-evident evidence block including input SHA-256 hash and confirmation that no data was retained and no external calls were made.
