You are charged both the fixed price for specific events and for Apify platform usage.

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). # README ## Blacklist & Spam Reputation Checker — DNSBL / RBL Lookup Check any IP address or domain against 16 active blacklists in one run. Get a reputation score, risk level, and a full per-list breakdown — no API key, no signup, no scraping. Used by email marketers checking sender reputation, security teams auditing infrastructure, and developers enriching domain or IP data in their pipelines. --- ### What it checks The Actor queries a curated set of 16 DNS-based blacklists (DNSBLs) that are: - Free for commercial use with no cloud IP restrictions - Currently active and maintained - Not known for excessive false positives Lists are automatically split by target type — IP lists for IP inputs, domain lists for domain inputs. #### IP Blacklists (9 lists) | List | Tier | About | |---|---|---| | `b.barracudacentral.org` | Critical | Barracuda Networks — used by major enterprise mail filters | | `bl.spamcop.net` | Critical | SpamCop — aggregates spam reports from users worldwide | | `spam.abuse.ch` | High | abuse.ch — tracks active spam infrastructure | | `drone.abuse.ch` | High | abuse.ch — tracks botnet and drone IPs | | `bl.0spam.org` | Medium | 0spam — free community-maintained blocklist | | `rbl.0spam.org` | Medium | 0spam — secondary RBL zone | | `ips.backscatterer.org` | Medium | WPBL — backscatter spam sources | | `psbl.surriel.com` | Medium | PSBL — passive spam block list | | `dnsbl.spfbl.net` | Medium | SPFBL — reputation-based blocklist | #### Domain Blacklists (7 lists) | List | Tier | About | |---|---|---| | `multi.surbl.org` | Critical | SURBL — domains found in spam message bodies | | `black.uribl.com` | Critical | URIBL — URI-based domain blacklist | | `dbl.nordspam.com` | High | NordSpam — free for all commercial use, no restrictions | | `uribl.spameatingmonkey.net` | High | SpamEatingMonkey — URI domain blocklist | | `fresh.spameatingmonkey.net` | Medium | SpamEatingMonkey — recently listed domains | | `rbl.0spam.org` | Medium | 0spam domain zone | | `dnsbl.spfbl.net` | Medium | SPFBL domain reputation | --- ### Scoring | Score | Label | Meaning | |---|---|---| | 100 | Clean | Not listed on any blacklist | | 85–99 | Low Risk | Listed on one or more medium-tier lists only | | 70–84 | Medium Risk | Listed on high-tier list(s) | | 1–69 | High Risk | Listed on multiple high-tier lists | | 0 | Critical | Listed on one or more critical-tier lists | Each critical listing deducts 30 points, high deducts 15, medium deducts 5. --- ### Input | Field | Type | Required | Description | |---|---|---|---| | `target` | string | Yes | IPv4 address (e.g. `8.8.8.8`) or domain name (e.g. `example.com`) | The Actor auto-detects whether the input is an IP or domain and queries the appropriate lists automatically. --- ### Example output — clean IP ```json { "target": "8.8.8.8", "targetType": "ip", "checkedAt": "2026-04-25T21:00:31.131Z", "totalChecked": 9, "totalListed": 0, "totalClean": 9, "reputationScore": 100, "reputationLabel": "Clean", "riskLevel": "none", "criticalListings": 0, "results": [ { "list": "b.barracudacentral.org", "tier": "critical", "listed": false }, { "list": "bl.spamcop.net", "tier": "critical", "listed": false } ] } ```` ### Example output — listed IP ```json { "target": "1.2.3.4", "targetType": "ip", "totalChecked": 9, "totalListed": 1, "reputationScore": 95, "reputationLabel": "Medium Risk", "riskLevel": "medium", "criticalListings": 0, "results": [ { "list": "dnsbl.spfbl.net", "tier": "medium", "listed": true, "responseCode": "127.0.0.4" } ] } ``` *** ### Use cases **Email deliverability** Before sending a campaign, check your sending IP and domain against all major blacklists. A single critical listing can cause Gmail, Outlook, and Yahoo to reject your mail entirely. **Security & infrastructure auditing** Check every IP in your server fleet or every domain in your vendor list. Integrate into your CI/CD pipeline or scheduled monitoring workflow via the Apify API. **Lead enrichment & CRM hygiene** Before reaching out to a prospect domain, verify it isn't blacklisted. Emailing a domain that's on SURBL or URIBL signals to receiving servers that your list hygiene is poor. **Threat intelligence** Check suspicious IPs or domains encountered in logs, headers, or incident reports against active threat-tracking lists like abuse.ch. *** ### Integrate via API ```bash curl -X POST \ "https://api.apify.com/v2/acts/obicodes~blacklist-reputation-checker/run-sync-get-dataset-items?token=YOUR_TOKEN" \ -H "Content-Type: application/json" \ -d '{"target": "8.8.8.8"}' ``` *** ### Pricing - **$0.05** Actor start fee (once per run) - **$0.01** per result A complete blacklist check costs **$0.06 total**. # Actor input Schema ## `target` (type: `string`): The IPv4 address or domain name to check (e.g. 1.2.3.4 or example.com) ## Actor input object example ```json { "target": "google.com" } ``` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "target": "google.com" }; // Run the Actor and wait for it to finish const run = await client.actor("obicodes/blacklist-reputation").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
