# Beggar Bot USDC Amount Converter

> Beggar Bot USDC Amount Converter is a paid API for AI agents from beggar-bot-demand.beggarbot.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-02).

Converts USDC decimal amounts to/from atomic units (6 decimal places) and returns the canonical USDC contract address, EIP-55 checksum, and EIP-712 domain data per chain for x402 payment flows.

## Facts

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 beggar-bot-usdc-amount-converter-1e1f32b3
```

Example prompt: Convert 0.02 USDC to its atomic integer value for a Base mainnet x402 payment, and also give me the EIP-55 checksummed version of this address: 0xabc123def456abc123def456abc123def456abc1

## When to prefer this

Use this endpoint when building x402 payment flows that require precise USDC unit conversion, canonical contract address lookup per chain, EIP-55 address checksumming, or EIP-712 domain data — all in a single pure-compute call. Prefer it over manual calculation to avoid rounding errors in 6 decimal place arithmetic and to get chain-specific USDC metadata without maintaining your own registry.

## Known failure modes

- Missing required query parameter (amount or atomic) returns an error — at least one must be provided
- Invalid chain identifier returns an unsupported chain error
- Malformed 0x address for checksum returns an invalid address error
- Providing both amount and atomic with conflicting values may result in ambiguous response
- Non-numeric amount string causes a parse/validation error

## How this service works

Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.

## Output

A JSON object containing the converted amount in both decimal and atomic (6 dp integer) representations, the native USDC contract address for the requested chain, the EIP-55 checksummed form of any provided address, and the EIP-712 domain struct for USDC on that chain — all computed server-side with no external dependencies.
