# Mekong Trade Intel — Crypto-Secure Random Integer & Hex API

> Mekong Trade Intel — Crypto-Secure Random Integer & Hex API is a paid API for AI agents from api.mekongtradeintel.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-25).

Generates a cryptographically secure random integer and hex value per call, suitable for salts, nonces, lotteries, and A/B assignments.

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 mekong-trade-intel-crypto-secure-random-integer-hex-api-af4da7bb -d '<json body>'
```

Example prompt: Give me a crypto-secure random integer and hex value right now — I need it for a nonce in my signing flow.

## When to prefer this

Prefer this endpoint when you need verifiably crypto-secure randomness (not pseudo-random) for security-sensitive applications like nonce generation, salts, or fair lotteries, and you are already operating in an x402/Base USDC micropayment environment. It is not suitable when you need large batches of random numbers cheaply, as per-call pricing applies.

## Known failure modes

- Payment not received or insufficient USDC balance causes 402 error
- Malformed POST body missing required 'input' object returns validation error
- Service temporarily unavailable returns 5xx with no random output
- Network timeout with no response if upstream service is degraded

## How this service works

Random number API for AI agents — crypto-secure random int + hex per call, $0.001 USDC on Base. Salts, nonces, lotteries, A/B assignment.

## Output

Returns a cryptographically secure random integer and a random hex string per call, suitable for use as salts, nonces, lottery picks, or A/B assignment seeds.
