# market2000.xyz Agent-Demand Intelligence (Top Endpoints)

> market2000.xyz Agent-Demand Intelligence (Top Endpoints) is a paid API for AI agents from market2000.xyz, paid per call via x402, $5/call, status unknown (last checked 2026-09-15).

Returns the top endpoints ranked by AI agent payment-quote requests over a configurable lookback window, revealing what the agent economy is actively trying to buy.

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 market2000-xyz-agent-demand-intelligence-top-endpoints-13a671aa
```

Example prompt: Show me the top 25 most in-demand x402 endpoints that AI agents have been requesting payment quotes for over the last 7 days — ranked by how many quotes were triggered.

## When to prefer this

Use this endpoint when you need real revealed-intent demand data about the x402 agent economy — i.e., which endpoints agents are actually willing to pay for, not just which ones exist. Prefer it over supply-side census endpoints when you want buyer-side signals. Ideal for market research, deciding what to build, tracking weekly trends in agent purchasing behavior, or understanding category-level demand distribution.

## Known failure modes

- days parameter out of range 1-90 returns validation error
- limit parameter out of range 1-100 returns validation error
- insufficient data for the requested window returns sparse or empty results
- endpoints seen by fewer than 3 distinct clients are withheld for privacy, reducing visible rows
- payment failure or x402 protocol error prevents call from completing

## How this service works

x402 Agent-Demand Intelligence — what AI agents actually try to buy, ranked.

Derived from the live request log of an origin that x402 agent crawlers already index: 402 payment quotes are revealed intent (an agent asked the price of a call), so the ranking shows what the agent economy is shopping for right now, by endpoint and by category.

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

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

RESPONSE: endpoints[] ranked by payment quotes, each with category, hits, and a bucketed buyer count; by_category[] rollup; coverage metadata.

PRIVACY: aggregate-only. No per-client logs are sold. Rows seen by fewer than 3 distinct clients are withheld and client counts ship as buckets.

PRICING: $0.05 per call.

## Output

A JSON object containing an array of endpoints ranked by number of x402 payment quotes received, each entry including endpoint URL, category, total hit count, and a bucketed distinct-buyer count; plus a by_category rollup summarizing demand across service types and coverage metadata about the observation window.
