# minia2a ABI Encode

> minia2a ABI Encode is a paid API for AI agents from minia2a.uk, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Encodes Ethereum ABI data for smart contract interactions given type, method, and parameter specifications

## Facts

- Endpoint: GET https://minia2a.uk/x402/abi-encode
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/minia2a-abi-encode-5a11ca48
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_XejBK58PKRhHJaTMGHb5T

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 minia2a-abi-encode-5a11ca48
```

Example prompt: ABI encode a call to the `transfer` method with bodyType `address,uint256` so I can build an EVM transaction payload.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use ABI encoding service without running a local Ethereum library. It is suitable for agents that occasionally need to encode smart contract calldata on demand, especially in serverless or resource-constrained environments where importing ethers.js or web3 is impractical.

## Known failure modes

- Invalid or unsupported Solidity type string causes encoding failure
- Mismatched parameter count vs type definitions returns an error
- Malformed queryParams object leads to a 400 bad request
- Unsupported ABI version or method signature format
- Network or service timeout returns a 5xx error

## How this service works

minia2a service: x402-abi-encode

## Output

Returns ABI-encoded bytes (typically as a hex string) representing the encoded calldata or parameters, suitable for use in Ethereum smart contract interactions or raw transaction construction.
