# Blockpin Agent Income Rebuild

> Blockpin Agent Income Rebuild is a paid API for AI agents from check.blockpin.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Reconstructs an agent wallet's income from payments in a single asset (ERC-20 or native ETH) over a block range, filtering out mints, zero-value transfers, self-transfers, and optional owner top-ups, with contract-payer flagging and optional claim reconciliation.

## 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 blockpin-agent-income-rebuild-843072b6
```

Example prompt: Can you rebuild the income statement for my agent wallet 0xAbc...123 in USDC (0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48) on Base from block 14000000 to block 14100000, excluding top-ups from owner 0xDef...456, and check whether it matches my claimed total of 500 USDC?

## When to prefer this

Use this endpoint when you need a clean, filtered income reconstruction for a specific agent wallet in a single asset over a defined block range — especially when you want automatic exclusion of noise (mints, zeros, self-transfers, owner top-ups), contract-payer flagging, and optional claim reconciliation. Prefer this over raw transfer queries or block explorers when building Agent Income Statements or auditing agent earnings on Ethereum, Base, or Robinhood Chain.

## Known failure modes

- Missing required params (chain, address, token, since) returns a 400-level error
- Block range exceeding chain limits (e.g. >1,000,000 blocks back on Ethereum) may return an error or truncated results
- Invalid token address or unrecognized chain enum returns an error
- Payment required (402) if no x402-compliant payment header is included
- Very large block ranges with high transfer volume may time out or return partial data
- If the address has no qualifying income in the range, returns zero income with empty payer list

## How this service works

Agent income rebuild: every payment into an agent wallet in one asset (an ERC-20, or native ETH including escrow withdrawals) between two blocks, with the draft Agent Income Statements exclusions (zero, mints, self, optional owner top-ups), payers that are contracts flagged, and an optional claim= compared as matched or mismatched. Ethereum, Base and Robinhood Chain. Independent, by Blockpin; not a Claus Network service.

## Output

Returns a structured JSON object with a plain-English summary, a breakdown of qualifying income (amounts per payer, total), excluded transfers (zeros, mints, self-transfers, owner top-ups) with counts, a list of all payers with contract flags, the largest individual payments, and — if a claim was provided — a matched or mismatched status comparing the claimed total against the computed income.
