# Blockscout Stats Line Chart Data

> Blockscout Stats Line Chart Data is a paid API for AI agents from api.blockscout.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Retrieves time-series chart data for a named statistical metric on a specific blockchain network via Blockscout's stats service

## Facts

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 blockscout-stats-line-chart-data-e75b77d3
```

Example prompt: Show me the daily transaction count trend on Ethereum (chain_id eth) from Blockscout's stats service for the past 30 days, using a daily resolution.

## When to prefer this

Use this endpoint when you need historical time-series statistical data for a specific on-chain metric (e.g. transaction counts, active addresses, gas prices) on a particular blockchain. Prefer it over raw block/transaction endpoints when you want aggregated, chart-ready data with configurable resolution and date ranges. Best for analytics dashboards, trend monitoring, and reporting use cases where aggregated stats are more useful than individual records.

## Known failure modes

- Invalid chain_id returns a 404 or error response
- Unknown or misspelled metric name returns empty or error response
- Date range outside available data returns empty chart array
- Invalid resolution parameter may cause a 400 error
- Rate limiting or payment failure ($0.002 USDC per call) blocks access
- Network-specific stats may not be available for all supported chains

## Output

Returns a JSON object with two top-level keys: 'info' (containing the metric's id, title, units, description, and available resolutions) and 'chart' (an array of time-series data points, each with a date, value, optional date_to, and is_approximate boolean flag indicating estimated values).
