# x402 Ecosystem Population Statistics

> x402 Ecosystem Population Statistics is a paid API for AI agents from intel.opusai.work, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-01).

Returns aggregated market-wide statistics for the x402 machine-payment ecosystem, including wallet demand concentration, repeat usage, bilateral vs open-market volume splits, pricing, and category breakdowns.

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 x402-ecosystem-population-statistics-dae58d2c
```

Example prompt: Give me the current x402 ecosystem snapshot — how many providers and resources are active, what the demand concentration looks like, what share of volume is bilateral versus open-market, and how the numbers compare to yesterday.

## When to prefer this

Choose this endpoint when you need an unbiased, aggregate, market-wide view of the x402 machine-payment ecosystem — especially for understanding demand concentration, bilateral vs open-market volume split, or ecosystem growth trends. It does not rank or endorse individual providers, making it ideal for neutral market intelligence. Prefer alternatives if you need to look up a specific provider's stats, search for services matching a use case, or need historical time series beyond daily deltas.

## Known failure modes

- No query parameters supported beyond what the schema exposes — malformed property names return default or empty results
- Daily snapshot comparisons may be unavailable if the prior day's data has not yet been computed
- Rate-limited or throttled if called excessively without payment
- If the x402 network has low coverage for a given day, counts and deltas may reflect incomplete data

## How this service works

Population statistics for the x402 machine-payment market. Bands paid volume by how many distinct wallets paid for each endpoint, separating open demand from volume running between a single buyer and seller. Returns demand concentration, repeat-usage distribution, pricing, metadata quality, category mix with demand per listing, and day-over-day change from our own daily snapshots. No provider is named, rated or endorsed.

## Output

A JSON object with schema version 'ecosystem.v1' containing: provider and resource counts, 30-day call totals, repeat-usage metrics (median calls per wallet, share of single-use buyers), demand concentration (top-1% share of calls, providers needed to reach half of volume), market structure (bilateral vs contestable share of calls), category mix with per-category demand, and day-over-day deltas derived from daily snapshots.
