# ADH Financial Intelligence Layer — China Population Data

> ADH Financial Intelligence Layer — China Population Data is a paid API for AI agents from agentdatum.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Returns China's total population figures (World Bank SP.POP.TOTL) with source attribution, collection timestamp, and data type classification for AI agent consumption.

## 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 adh-financial-intelligence-layer-china-population-data-f30cfc43
```

Example prompt: Pull the latest China total population figure from the World Bank data feed — I need the most recent value with its source and collection date for my macro analysis.

## When to prefer this

Choose this endpoint when you need a fast, pre-cleaned, source-attributed China population figure without setting up a World Bank API key yourself — especially useful when injecting demographic context into AI agent reasoning pipelines at low cost ($0.01 USDC) via x402 micropayment settlement.

## Known failure modes

- Payment not settled via x402 — returns 402 Payment Required
- World Bank upstream unavailable — may return stale or empty data
- Rate limit exceeded — returns 429 error
- Malformed request headers — returns 400 Bad Request
- Data not yet updated for most recent year — returns prior year value
