# market2000.xyz Unmet Agent Demand

> market2000.xyz Unmet Agent Demand is a paid API for AI agents from market2000.xyz, paid per call via x402, $5/call, status unknown (last checked 2026-09-16).

Returns aggregated data on API endpoints that AI agents tried to reach but were blocked by 404/401/403 responses, revealing unmet demand from real agent clients.

## 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 market2000-xyz-unmet-agent-demand-e414a480
```

Example prompt: Pull the top 25 unmet demand signals from agent traffic over the last 7 days — I want to see which endpoint categories are getting the most 404s and 401/403 blocks from real AI agent clients.

## When to prefer this

Choose this endpoint when you need real observed demand signals from actual AI agent traffic rather than self-reported or survey-based intent data. It is uniquely valuable because the 404/401/403 signals are only visible to the origin receiving the requests, making this dataset impossible to reconstruct from public marketplace or bazaar data. Prefer it over declared-intent endpoints when you want behavioral evidence of what agents are actually trying to buy, not just what they say they want.

## Known failure modes

- No data returned if the lookback window has insufficient traffic
- Rows suppressed when fewer than 3 distinct clients made the request (privacy threshold)
- days parameter outside 1-90 range or limit outside 1-100 may return an error
- Payment failure if USDC balance is insufficient for the $5 per-call fee
- Empty result set during low-traffic periods or for very narrow time windows

## How this service works

Unmet agent demand — the endpoints agents ask for and cannot get.

404s and gated 401/403s from real (non-scanner) agent clients: a shopping list with the customers already attached. This cut is invisible to anyone who is not the origin being asked, which is why it cannot be reconstructed from public bazaar data.

HOW TO CALL:
  GET /api/demand/unmet?days=7&limit=25

PARAMETERS:
  days  — lookback window, 1-90 (default 7)
  limit — rows returned, 1-100 (default 25)

RESPONSE: unmet[] sorted by volume, each with the signal (404/401/403), category, hit count and bucketed count of distinct askers.

PRIVACY: aggregate-only; rows below 3 distinct clients withheld.

PRICING: $0.05 per call.

## Output

An array of unmet demand records sorted by volume, each containing: the HTTP signal type (404, 401, or 403), category label, raw hit count, and a bucketed count of distinct agent clients that made the request. Rows with fewer than 3 distinct clients are withheld for privacy.
