# Particle Pro: List Entity Charts

> Particle Pro: List Entity Charts is a paid API for AI agents from api.particle.pro, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Returns all entity charts with headline state of their current edition, including edition date, narrative status, and the rank-1 entity, optionally filtered by a 7d or 24h measurement window.

## 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 particle-pro-list-entity-charts-e380f26a
```

Example prompt: Show me all the entity charts from Particle Pro for the last 24 hours — I want to see each chart's edition date, whether narratives have been written, and what entity is sitting at rank 1.

## When to prefer this

Use this endpoint when you need a high-level overview of all entity charts at once — particularly to check which entities lead each chart, whether editorial narratives are complete, and what the edition dates are. Prefer this over individual chart lookups when doing a sweep or dashboard-style summary across all entity chart types.

## Known failure modes

- Invalid window value (not '7d' or '24h') returns a validation error
- No charts available for the requested window returns an empty list
- Authentication or payment failure (x402) returns a 402 Payment Required
- API unavailability returns a 5xx error

## How this service works

List entity charts. Returns every entity chart with the headline state of its current edition: the edition date, whether narratives have been written yet, and what sits at rank 1.

## Output

A list of all entity charts, each with its current edition's headline state: the edition date, a flag indicating whether narratives have been written, and the entity occupying rank 1 in that edition. The optional window parameter (24h or 7d) scopes which editions are summarized.
