## Pricing

from $6.80 / 1,000 results

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?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

The most complete Farcaster cast scraper available. It returns every field a public cast exposes, including full author profile and follower counts, all engagement metrics with a combined recast total, thread and reply structure, embedded images and links, channel tags, plus optional AI enrichment, and gives you username, FID and keyword inputs to target exactly the casts you need.

### What it does

The actor collects public Farcaster casts by username, by numeric FID, or by keyword search, and writes one normalized record per cast to the run's dataset. Each record carries the cast hash and text, the cast time (ISO and epoch), the full author profile (FID, username, display name, follower and following counts, bio, avatar), all engagement metrics (replies, reactions, recasts, quotes, watches, views, and a combined recast total), the thread and reply structure, embedded image and link counts with the first of each, channel tags, and the Warpcast URL. You can require a minimum reaction count and choose whether replies are included. Missing source values are returned as `null`.

Two opt-in AI add-ons (paid Apify plans only) can classify each cast's sentiment (`withAiSentiment`) and tag it with topics (`withAiTopics`).

### Quickstart

Open the actor, paste this into the input, and press Run. It returns up to 15 recent casts from two accounts plus a keyword search, replies included.

```json
{
  "usernames": ["dwr.eth", "vitalik.eth"],
  "searchQueries": ["base"],
  "maxCasts": 15,
  "includeReplies": true
}
```

Provide at least one of `usernames`, `fids`, or `searchQueries`. All inputs combine into one run, and each record is tagged with the `sourceType`/`sourceValue` that produced it.

### Input reference

| Field | Type | Required | Default | Description |
|---|---|---|---|---|
| `usernames` | string\[] | no | `["dwr.eth"]` | Farcaster usernames to fetch casts from, with or without `@`. One run does the whole list. |
| `fids` | string\[] | no | (empty) | Farcaster IDs (numeric) to fetch casts from, as an alternative to usernames. |
| `searchQueries` | string\[] | no | (empty) | Keywords or phrases to search casts for, for example `base`, `ethereum`, `AI agents`. |
| `includeReplies` | boolean | no | `true` | Include reply casts. Turn off to keep only top-level casts. |
| `minReactions` | integer | no | (none) | Keep only casts with at least this many reactions (likes). |
| `maxCasts` | integer | no | `50` | Maximum casts to collect across all inputs. Free Apify plans are capped at 10 per run. |
| `withAiSentiment` | boolean | no | `false` | Paid AI add-on. Classify each cast's sentiment (positive/neutral/negative) with a score. |
| `withAiTopics` | boolean | no | `false` | Paid AI add-on. Tag each cast with 1 to 5 topics. |

Provide at least one of `usernames`, `fids`, or `searchQueries`.

### Run via API and CLI

Start a run and wait for it to finish, then read the dataset. Replace `<TOKEN>` with your Apify API token.

Run synchronously and get dataset items in one call:

```bash
curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~farcaster-casts-scraper/run-sync-get-dataset-items?token=<TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"usernames":["dwr.eth"],"maxCasts":25,"includeReplies":false}'
```

Start a run asynchronously:

```bash
curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~farcaster-casts-scraper/runs?token=<TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"searchQueries":["base","AI agents"],"minReactions":50,"maxCasts":200}'
```

Apify CLI:

```bash
apify call scrapers_lat/farcaster-casts-scraper \
  --input '{"usernames":["vitalik.eth"],"maxCasts":10}'
```

### Fetch results

Every run writes to a dataset. Fetch items as JSON, CSV, or Excel by changing `format`:

```bash
## JSON
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&clean=true&format=json"

## CSV
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&clean=true&format=csv"

## Paginate large datasets
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&offset=1000&limit=1000"
```

`<DATASET_ID>` is returned as `defaultDatasetId` in the run object. Use `offset` and `limit` to page through large result sets. `clean=true` drops empty and internal fields.

### Billing and limits

- **Pay per result.** You are charged per cast returned (`result` event). See the [pricing tab](https://apify.com/scrapers_lat/farcaster-casts-scraper/pricing) for the current per-result price.
- **AI add-ons bill separately.** Sentiment and topics are opt-in, off by default, and each carry their own per-item charge.
- **No charge on failure.** If a run errors, the actor writes a single item with a populated `error` field and does not charge for it. Empty runs cost nothing.
- **Spend cap respected.** Set `maxTotalChargeUsd` on the run; once reached, the actor stops emitting and charging further billable results.
- **Free Apify plans** are capped at 10 records per run. Upgrade for higher `maxCasts`.

### FAQ and troubleshooting

**A run returned 0 records. Why?**
The usernames or FIDs may have no matching casts under your filters (for example `minReactions` too high, or replies excluded), or the keyword matched nothing. Loosen the filters. Zero-result runs are not charged.

**Can I mix usernames, FIDs and keywords?**
Yes. All three inputs combine into one run and each record is tagged with the `sourceType` and `sourceValue` that produced it.

**How do I get only high-engagement casts?**
Set `minReactions` to a threshold; only casts with at least that many reactions are kept.

**What is `combinedRecastCount`?**
Recasts plus quote casts, so you can rank by total amplification in one number.

**Is this an official Farcaster or Warpcast tool?**
No. This actor is independent and has no affiliation with Farcaster or Warpcast. It reads only publicly available cast data.
