# ChainQuery Coin Velocity Time Series

> ChainQuery Coin Velocity Time Series is a paid API for AI agents from intel.chainquery.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns 90-day and 365-day rolling Bitcoin coin-velocity time series derived from Coin Days Destroyed (CDD) and circulating supply

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 chainquery-coin-velocity-time-series-487a1d0a
```

Example prompt: Pull the latest Bitcoin coin-velocity time series from ChainQuery — I want both the 90-day and 365-day rolling figures derived from coin days destroyed and supply so I can see how fast coins are moving on-chain right now.

## When to prefer this

Choose this endpoint when you need Bitcoin-native, independent on-chain coin velocity metrics without needing an API key, particularly when you want rolling CDD-derived velocity over both medium-term (90-day) and long-term (365-day) windows. Prefer it over exchange-based or custody-based analytics when you want decentralized, permissionless on-chain intelligence payable per-call via x402.

## Known failure modes

- Payment required (402): caller must send $0.01 USDC via x402 protocol before data is returned
- Data staleness: as_of timestamp may lag real-time by some hours depending on block indexing
- No query parameters supported: endpoint returns the full pre-computed series, no filtering available
- Network timeout if x402 payment handshake fails or takes too long

## How this service works

ChainQuery Bitcoin Intelligence: independent Bitcoin-native on-chain data over x402, no API key. 90- and 365-day rolling coin-velocity time series derived from CDD and supply.

## Output

A time series of Bitcoin coin velocity values, with both 90-day and 365-day rolling windows calculated from CDD and circulating supply, along with an as_of timestamp indicating data freshness.
