Three steps to published replies

Get from zero to live Reddit & X comments in minutes, not weeks.

1

Get your API key

Sign up and get your key instantly. No credit card required for test mode.

2

Send a POST request

Pass the target URL and your reply text. We handle account selection, rate limits, and publishing.

3

Reply gets published

We publish from an aged account with karma and history, then return the live URL.

Built for reliability at scale

Everything you need to publish replies without managing accounts yourself.

Aged accounts with karma

Every reply is posted from accounts with real history, karma, and age. No fresh throwaway accounts that get flagged.

Content moderation

Built-in AI moderation flags spam, hate, and policy violations before publishing. Keep accounts safe.

Reply health monitoring

We track every reply after publishing. Get notified via webhook if a reply is removed or flagged by moderators.

Upvotes API

Boost visibility of your replies with organic-looking upvotes. Available as a separate endpoint.

Webhooks

Receive real-time status updates. Know immediately when a reply is published, pending, or removed.

Test mode

Validate requests without publishing. Test mode runs moderation and returns realistic responses. Free on all plans.

Built for your workflow

Whether you're building an AI agent or running a marketing team, DropReply fits right in.

AI Agents

Build agents that participate in Reddit & X conversations. Use our API as a tool in your LangChain, CrewAI, or custom agent pipeline.

Marketing Automation

Connect via n8n, Make.com, or Zapier. Automate replies when your brand or keywords are mentioned.

SaaS Products

Add "post to Reddit" as a feature in your product. Let your users publish through your app without managing accounts.

Agencies

Manage Reddit presence for multiple clients from one API key. Scale without hiring a social media team.

One request, one published reply

Send JSON, get a live comment on Reddit. It's that simple.

You send
{
  "platform": "reddit",
  "target_url": "https://reddit.com/r/SaaS/...",
  "content": "Great tool! We switched to
    ProductX and cut response
    time by 40%."
}
We publish
u/careful_penguin42 · r/SaaS · just now
Great tool! We switched to ProductX and cut response time by 40%.

Your risk: zero

  • Our accounts, our proxies. If one gets banned, we replace it.
  • Built-in content moderation prevents policy violations before publishing.
  • 50% credit refund if a reply is removed within 24 hours.

Simple to integrate

A single POST request. Works with any language, framework, or AI agent.

});

console.log(reply.id);     // rpl_a1b2c3d4e5f6

Frequently asked questions

Everything you need to know before integrating.

We maintain a pool of aged Reddit and X (Twitter) accounts with real karma, post history, and account age. Accounts are rotated to avoid detection patterns. You never need to provide your own accounts.

No, links are not allowed in replies. Our moderation system automatically blocks URLs, emails, and phone numbers to protect account health. Reddit and Twitter heavily penalize comments with links from non-established accounts. Instead, mention your product by name — users will Google it.

We monitor every published reply. If a reply is removed by a moderator, we notify you via webhook with the reason (if available). Removed replies don't count against your monthly quota, and you can retry with adjusted content.

Currently we focus on replies and comments, which have higher engagement rates and lower moderation risk. New post creation is on our roadmap. Contact us if this is a priority for your use case.

Yes. Use your test API key (prefixed with drpl_test_) to validate requests without actually publishing. Test mode returns realistic responses and runs content moderation, but nothing gets posted. Free on all plans.

Reddit and Twitter/X are both fully supported. Specify the platform in your API request. We're considering LinkedIn support in the future.
