## 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 walcert-wallet-funding-origins-grader-3d826a1d -d '<json body>'
```

Example prompt: Before I pay this agent, can you grade the funding origins of wallet 0x4B20993Bc481177ec7E8f571ceCaE8A9e22C02db — I want to know if it was funded by a mixer, bridge, or CEX, and get back an A-F score with a signed certificate?

## When to prefer this

Choose this endpoint when you specifically need to evaluate where a wallet's funds originated (CEX withdrawal, bridge inflow, mixer, or organic activity) rather than behavioral patterns, portfolio quality, or chain longevity. Ideal for pre-hire ERC-8004 agent vetting, compliance workflows requiring a signed and blockchain-anchored certificate of funding provenance, or any situation where mixer or bridge exposure is a disqualifying risk factor.

## Known failure modes

- Invalid or malformed wallet address (not 0x-prefixed or not 42 chars) — returns validation error
- Wallet has insufficient on-chain history to determine funding origin — may return low confidence or incomplete grade
- Payment of $0.05 USDC not received — request rejected with 402 Payment Required
- Network or Celo anchoring failure — certificate generation may be delayed or error out
- Wallet address exists but has no discernible funding transactions — grade may default to F or unknown

## How this service works

Before hiring or paying an ERC-8004 agent, grade the controlling wallet's funding origins (CEX, bridge, mixer, organic) A-F. POST wallet_address; signed certificate + Celo on-chain anchor. $0.05 USDC.

## Output

Returns an A-F letter grade reflecting the quality of the wallet's funding origins, categorized across sources such as CEX deposits, cross-chain bridges, mixers, and organic on-chain activity. Also includes a signed certificate and a Celo blockchain anchor proving the assessment, suitable for compliance records or pre-transaction vetting.
