# Anansi Data Velocity Movers

> Anansi Data Velocity Movers is a paid API for AI agents from anansidata.xyz, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Ranks keys by how fast they are moving on a specified field over a given time window, derived from Anansi's proprietary archive.

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 anansi-data-velocity-movers-6a65a073
```

Example prompt: Which keys are moving the fastest on the 'price' field in the 'crypto_assets' dataset over the last 6 hours? Give me the top 10 movers ranked by velocity.

## When to prefer this

Choose this endpoint when you need to identify which keys or items are accelerating or decelerating fastest within a dataset over a specific window — particularly when upstream sources don't offer velocity or rate-of-change views. It is purpose-built for momentum detection and trend surfacing, distinct from raw current-value lookups or anomaly/outlier detection offered by sibling endpoints.

## Known failure modes

- Unknown dataset or field name returns an error or empty result
- Time window too short to compute meaningful velocity — may return sparse or zero-velocity rankings
- Rate limit or payment failure returns a 402 or 429 error
- Invalid or malformed request body returns a 400 validation error
- Field has no historical archive data, making velocity computation impossible

## How this service works

Velocity ranking: which keys are moving fastest on a field over a window. Derived from the archive; exists nowhere upstream.

## Output

A ranked list of keys ordered by their velocity (rate of change) on the specified field over the requested window, including velocity scores or rates derived from the Anansi archive — data that is not available from upstream sources.
