> Agentic Finance Graph – Builder Check is a paid API for AI agents from agenticfinancegraph.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Looks up the coded payment history, counterparty spend breakdown, and builder code share for a specific ERC-8004 agent on Base by token ID, slug, or bound wallet address.

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 agentic-finance-graph-builder-check-bc20d6fc
```

Example prompt: Pull the builder code payment breakdown for ERC-8004 agent with token ID 8004-base-53008 — I want to see how much USDC it paid, how many payments were coded, and what share of coded USD each builder code accounts for.

## When to prefer this

Use this endpoint when you specifically need builder code attribution data for an ERC-8004 agent — i.e. which builder codes are associated with an agent's payments, the USD assigned per code, and the share of coded vs total payments. Prefer sibling endpoints for liveness rank, drain shape, counterparty breakdown, or incident history.

## Known failure modes

- 404 returned if agent has not reached rank L7+ (i.e. has not been observed paying a counterparty — no record exists before payment)
- 404 if the provided token ID, slug, or wallet address does not match any registered ERC-8004 agent
- 402 Payment Required if the x402 payment header is missing or incorrect
- Invalid query parameter format returns a validation error

## How this service works

Which apps move its money: The ERC-8021 Builder Codes on this agent's counted payments: payments, USD and share per code, the top payee per code, and how much of its counted spending has been read so far. About one ERC-8004 agent on Base, by Agentic Finance Graph. id = token id, slug or bound wallet; an agent never seen paying is a 404 before any payment.

## Output

Returns a JSON object with the agent's ID, an as-of timestamp, the check type ('check.builders'), an array of builder code entries each containing the code identifier, kind, number of payments, USD amount, and share of coded USD percentage, plus totals covering coded payment count, counted payment count, and read share percentage.
