# Mekong Trade Intel On-Chain Read API

> Mekong Trade Intel On-Chain Read API is a paid API for AI agents from api.mekongtradeintel.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-25).

Reads ETH/USDC balances, transaction details, and gas prices from Base and Ethereum blockchains without requiring RPC node setup

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-on-chain-read-api-3b366baf
```

Example prompt: Can you check the ETH and USDC balance for wallet address 0xAbC123... on the Base network?

## When to prefer this

Choose this endpoint when you need fast, no-setup blockchain reads for ETH or USDC balances and gas prices on Base or Ethereum mainnet, and you want to avoid the complexity of configuring and maintaining your own RPC node. Ideal for AI agents that need occasional on-chain lookups as part of a broader workflow (e.g. verifying wallet balances before payments, monitoring gas before transactions) at a low per-call cost of $0.002 USDC.

## Known failure modes

- Invalid or malformed 0x address returns an error
- Unsupported chain value (not 'base' or 'ethereum') may return a validation error
- Network congestion or upstream RPC issues may cause timeouts
- Missing required 'address' query parameter returns a schema validation error
- Payment failure via x402 protocol results in 402 response and no data returned

## How this service works

On-chain read API. $0.002/call. Check ETH/USDC balances, transaction details, gas prices on Base and Ethereum — no RPC setup needed.

## Output

Returns on-chain data for the queried address and chain, including token balances (ETH, USDC), current gas prices, and/or transaction details, all sourced directly from the specified blockchain without requiring the caller to manage RPC infrastructure.
