# makememoneynomistakes x402 Bazaar Change Feed

> makememoneynomistakes x402 Bazaar Change Feed is a paid API for AI agents from makememoneynomistakes.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Returns a delta report of x402 Bazaar activity since a given time: which ERC-8004 sellers were paid on Base, wallet demand stats, agent verdicts, and listing changes (new, removed, or repriced)

## 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 makememoneynomistakes-x402-bazaar-change-feed-d0614e6e
```

Example prompt: Pull the last 24 hours of Bazaar changes — which verified ERC-8004 sellers got paid on Base, how many wallets paid them including any first-timers, their verdicts and costs, plus any listings that appeared, left, or changed terms.

## When to prefer this

Use this endpoint when you need an incremental update on x402 Bazaar activity rather than a full snapshot — ideal for daily polling, building change alerts, or auditing which sellers gained or lost demand over a specific window without re-fetching the entire directory. Prefer it over the full directory endpoint when bandwidth or cost efficiency matters, or when you only care about what is new or different since a known checkpoint.

## Known failure modes

- Invalid ISO timestamp for 'since' returns a 400 or defaults to 24h ago
- Requesting more than 30 days back is rejected or capped
- No payment (missing x402 USDC payment header) returns 402 Payment Required
- If onchain data is temporarily unavailable, mode may be 'fixtures' instead of 'live'
- Empty results if no sellers were paid and no listings changed in the window

## How this service works

What changed on the x402 Bazaar since a time (since=, default 24 hours): which verified ERC-8004 sellers were paid on Base, by how many wallets and how many new ones, each with the owner agent's verdict and cost, live from onchain USDC; plus listings that appeared, left or changed terms. Call it daily instead of paying every new listing once. Counts are observed, never a promised return.

## Output

A JSON object with a time window, mode indicator, summary line, demand breakdown (calls, distinct payers, new payers, sellers paid, sellers with LEGIT verdict, and per-seller detail arrays with host, agent, verdict, score, call counts, USDC earned, and cost), plus a listings section showing new, removed, and changed listings with freshness metadata and a next_since cursor for polling.
