## Pricing

from $0.35 / 1,000 charts

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).

## Helm Repo Index Extractor

Point at **any** Helm chart repository's `index.yaml` and get one clean,
structured row per chart **version** — the entire repository catalogue as a flat
dataset you can filter, diff, inventory, or feed into an SBOM / supply-chain
pipeline.

Every Helm repository — [Prometheus Community](https://prometheus-community.github.io/helm-charts/index.yaml),
[Grafana](https://grafana.github.io/helm-charts/index.yaml),
[Jetstack / cert-manager](https://charts.jetstack.io/index.yaml),
[Bitnami](https://charts.bitnami.com/bitnami/index.yaml),
[HashiCorp](https://helm.releases.hashicorp.com/index.yaml),
[ingress-nginx](https://kubernetes.github.io/ingress-nginx/index.yaml),
and the tens of thousands of self-hosted and GitHub-Pages-hosted repos — publishes
the **identical** Helm repository index standard. So this one actor works against
all of them. No per-repo scraper, no host enumeration: give it an `index.yaml`
URL and it returns the whole catalogue.

### What you get

One dataset row per chart version, with every standard Helm index field
flattened and safely nullable (a repo that omits a field simply yields `null`):

| Field | Description |
| --- | --- |
| `chart` / `name` | Chart name |
| `version` | Chart version (SemVer) — one row each |
| `appVersion` | Version of the app the chart deploys |
| `chartApiVersion` | Chart schema (`v1` / `v2`) |
| `chartType` | `application` or `library` |
| `created` | Publish timestamp (ISO-8601) |
| `digest` | SHA-256 digest of the packaged chart |
| `description` | Chart description |
| `deprecated` | Whether the version is deprecated |
| `kubeVersion` | Compatible Kubernetes version range |
| `home` / `icon` | Project home URL / icon URL |
| `chartUrl` | Direct, absolute download URL of the `.tgz` (relative repo URLs resolved for you) |
| `urls` | Raw download URL list |
| `sources` | Source-code repository URLs |
| `keywords` | Chart keywords |
| `dependencies` | Sub-chart dependencies (name, version, repository, condition, …) |
| `maintainers` | Maintainers (name, email, url) |
| `annotations` | Chart annotations (e.g. ArtifactHub metadata) |
| `_raw` | The lossless original version entry |
| `_source`, `_chartCount`, `_versionCount`, `_chartVersionCount` | Provenance & totals |

### Input

| Field | Required | Description |
| --- | --- | --- |
| `indexUrl` | ✅ | URL of a Helm repository `index.yaml`. Redirects are followed. |
| `chartFilter` | | Case-insensitive substring; only matching chart names are emitted. |
| `maxRecords` | | Global cap on emitted rows (each row = one chart version). |
| `bearer` | | Bearer token for a private/gated repo. Never logged. |
| `extraHeaders` | | Extra request headers (JSON object) for gated repos. Never logged. |

#### Example

```json
{
  "indexUrl": "https://charts.jetstack.io/index.yaml",
  "chartFilter": "cert-manager",
  "maxRecords": 25
}
````

### Notes

- **Large repos:** a single popular chart can have hundreds of releases (Bitnami's
  index is tens of MB and holds thousands of versions). Use `maxRecords` and/or
  `chartFilter` to scope a run; charts are processed in sorted name order so a
  capped run is deterministic.
- **Robust by design:** fields are read by key presence, so a repository that
  omits `appVersion`, `dependencies`, `maintainers`, `type`, etc. never breaks the
  run — the missing column is simply `null`.
- **Honest failure:** if the URL doesn't return a Helm repository index (an HTML
  error page, a 404, or YAML without an `entries` map) the run fails fast rather
  than emitting empty rows.

### Pricing

Pay-per-event: **one `chart` charge per emitted chart-version row.** You only pay
for the rows you extract.

# Actor input Schema

## `indexUrl` (type: `string`):

URL of a Helm chart repository's index.yaml. Every Helm repo publishes the identical index standard, so one actor works against any of them: https://charts.jetstack.io/index.yaml (Jetstack / cert-manager), https://prometheus-community.github.io/helm-charts/index.yaml (Prometheus Community), https://grafana.github.io/helm-charts/index.yaml (Grafana), https://helm.releases.hashicorp.com/index.yaml (HashiCorp), https://kubernetes.github.io/ingress-nginx/index.yaml, or any self-hosted / GitHub-Pages repo. Redirects are followed (Bitnami's index 302-redirects). The URL usually ends in /index.yaml.

## `chartFilter` (type: `string`):

Optional case-insensitive substring. Only charts whose name contains it are emitted; charts that do not match are skipped entirely. Leave empty to extract every chart in the repository. Example: prometheus (matches kube-prometheus-stack, prometheus-node-exporter, …).

## `maxRecords` (type: `integer`):

A GLOBAL cap on the number of chart-version rows to emit (each row is one chart version and one billable event). Charts are processed in sorted name order, so a small cap is deterministic. Leave empty to emit every version of every chart — note a large repo can hold thousands of versions (a single chart may have hundreds of releases).

## `bearer` (type: `string`):

Optional bearer token for a private/gated Helm repository (sent as Authorization: Bearer \*\*\*). Not required for public repos. Never logged.

## `extraHeaders` (type: `object`):

Optional extra HTTP headers as a JSON object, e.g. {"x-api-key": "..."} for gated/authenticated repositories. Not required for public repos. Header values are never logged.

## Actor input object example

```json
{
  "indexUrl": "https://charts.jetstack.io/index.yaml"
