# Delx Commerce — EVM Amount Minimum Check

> Delx Commerce — EVM Amount Minimum 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).

Validates whether an EVM token amount (in raw units) meets a specified minimum threshold, returning sufficiency status and 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-amount-minimum-check-b7291a85 -d '<json body>'
```

Example prompt: Before I execute this EVM transaction, check if my available balance of 1000000 raw units is sufficient to meet the minimum requirement of 990000 raw units.

## When to prefer this

Use this endpoint when you need a fast, verifiable, privacy-preserving preflight check that an EVM raw token amount meets a minimum threshold — especially in agentic pipelines where you want cryptographic evidence of the check (input SHA-256, no data retention) without running your own comparison logic. Prefer it over custom code when auditability and pay-per-use pricing matter.

## Known failure modes

- Invalid or non-numeric string values for actual_raw or minimum_raw may cause a validation error
- Strings exceeding 8192 characters will be rejected
- Missing required fields returns an error response
- Malformed JSON body results in a 400-level error

## 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 with: a boolean 'sufficient' flag indicating if the actual amount meets the minimum, 'required_raw' and 'available_raw' strings for reference, 'shortfall_raw' showing how much is missing (0 if sufficient), plus evidence metadata including input hash and a confirmation that no data is retained or external calls made.
