**Category:** Government & Public Data | **Website:** [worldometers.info/](https://worldometers.info/) | **Docs:** [parse.bot/marketplace/f8834cdf-439d-4d36-ab03-1e9be0bcbda0/worldometers-info-api](https://parse.bot/marketplace/f8834cdf-439d-4d36-ab03-1e9be0bcbda0/worldometers-info-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.beta.paywithlocus.com/api/wrapped/credits/worldometers/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get country populations

Get the full list of countries and their populations, including rank, yearly change percentage, net change, density per km², land area, and world share. Returns all 234 countries in a single response ordered by population rank.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/worldometers/get-country-populations \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get historical data

Get historical world population data by year, including yearly change percentage and absolute yearly change figures. Covers years from 2026 back to 1951, ordered most recent first.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/worldometers/get-historical-data \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### Get population projections

Get future world population projections by year through 2100, including yearly change percentage and absolute yearly change figures. Covers years from 2026 to 2100, ordered earliest first.

**Estimated cost:** Metered

  -H "Content-Type: application/json" \
  -d '{}'
```

### Get world population stats

Get general world population statistics, including the current population estimate, recent historical highlights by year, and population breakdown by region with world share percentages. Returns a single snapshot object containing all three data sets in one call.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/worldometers/get-world-population-stats \
