> Delx EVM Amount Min Check is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Checks whether a raw EVM token amount meets or exceeds a required minimum threshold, returning sufficiency status and shortfall details.

## 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-evm-amount-min-check-a02cb791 -d '<json body>'
```

Example prompt: Before executing the swap, check if the available raw amount of 1000000 meets the minimum required raw amount of 990000 on EVM — tell me if it's sufficient and by how much.

## When to prefer this

Use this endpoint when you need a lightweight, auditable, in-memory preflight check that a raw EVM token amount meets a minimum before committing to a blockchain transaction, swap, or payment. It is preferable over doing this comparison locally when you need a logged, hashable evidence trail or when operating within an agent pipeline that requires governed service calls. It does not make on-chain calls itself — it is purely a computation over two numeric strings.

## Known failure modes

- Missing or malformed actual_raw or minimum_raw strings may cause a 400 validation error
- Non-numeric string values for raw amounts will likely result in a processing error
- Extremely large numeric strings exceeding maxLength of 8192 characters will be rejected
- Network timeout or service unavailability returns a 5xx error

## How this service works

EVM Amount Min Check: EVM Amount Min Check checks an actual raw amount against a minimum raw amount from bounded caller-supplied values without an external provider. Call EVM Amount Min Check before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for EVM Amount Min Check as versioned deterministic JSON. Price: $0.001 USDC via x40…

## Output

Returns a JSON object with a boolean 'sufficient' field, the required_raw amount, available_raw amount, and shortfall_raw (zero if sufficient). Also includes operation metadata, input hash for auditability, and confirmation that no data was retained.
