SkillTweet - The Store for X Growth Skills: 90% share + 30% API royalty

The problem

You built a great skill. It doesn't sell.

You can write an excellent X growth skill — but right now it's just a file. Where do buyers find it? And after they pay once, how does it ever pay you a second time?

A SKILL.md with no distribution channel.
One-off sale, then the revenue hits zero.
The platform takes 20% and ignores your API calls.
Foreign payment rails lock out domestic buyers.

Result? A great skill sitting on your disk, sold exactly zero times.

Selling 100 copies of a $9 skill

ClawMart (20% fee)$720

SkillTweet one-off (10% fee)$810

SkillTweet API royalty+$810 / yr

Same buyers, same skill, $900 apart over a year. The gap isn't charged to buyers — it's a smaller platform fee plus usage that becomes a recurring stream.

The solution

SkillTweet is your skill store.

Discovered like Product Hunt. Bought once like Gumroad. Plus an API royalty that keeps flowing.

🛒

Buy once

The buyer pays once and owns the SKILL.md + API key forever.

⚡

Bundled API quota

You set how many calls ship with the skill; SkillTweet meters and deducts them.

💸

You keep 90%

The platform takes 10% — half of ClawMart's 20%.

🔁

30% lifetime royalty

When buyers keep calling after the quota runs out, you take 30% every time.

How it works

From SKILL.md to your first dollar in 5 steps

Write a file, grab a key, publish with one curl. SkillTweet handles the rest.

Step 011

Write a SKILL.md

The Agent Skills standard: a frontmatter block and a markdown body. Say what the skill does and what it needs.

SKILL.md

---
name: Auto-Reply Safe
description: Reply to X mentions with on-brand,
  safety-checked drafts.
tags: [Auto-Reply, Safety]
---
# Auto-Reply Safe
Drafts replies in your brand voice.
Every draft waits for a human click.

Step 022

Get an API key

Create a creator account. The key appears in the response exactly once — save it, then forget about it.

create creator

curl -X POST https://api.skilltweet.com/api/v1/creators \
  -H "Content-Type: application/json" \
  -d '{"handle":"your_handle","email":"you@example.com"}'
# -> { "meta": { "api_key": "sk_live_..." } }

Step 033

Publish with one curl

POST /api/v1/listings — ClawMart compatible, same fields as everywhere else. Or publish from a directory with the CLI.

publish

curl -X POST https://api.skilltweet.com/api/v1/listings \
  -H "Authorization: Bearer $SKILLTWEET_API_KEY" \
  -d '{"name":"Auto-Reply Safe","price_usd":9,
       "api_calls_included":10000,"skill_md":"..."}'
# or: npx skilltweet publish --from-dir .

Step 044

Buyers pay once

They get the SKILL.md, an API key bound to their own identity, and a call quota. Alipay, WeChat and cards all work.

purchase

POST /api/v1/purchases
{ "listing_id": "lst_...", "email": "buyer@example.com" }
# -> { "data": { "api_key": "sk_buyer_...",
#      "calls_included": 10000, "price_paid_usd": 9 } }

Step 055

Quota runs out, calls continue

Usage flows straight into your 30% lifetime royalty and settles monthly. No chasing invoices, no shipping anything.

payouts

GET /api/v1/creators/your_handle/payouts
{ "period": "2026-11",
  "sales_usd": 810, "api_royalty_usd": 67.5 }
# 100 buyers -> $810 one-off + $67.5 / month

A listing is the product. Price, included calls, tags and the full SKILL.md all live here — exactly what the buyer sees.

calling the X data behind a skill

GET /v1/tweets?ids=tweet_1,tweet_2

{
  "data": [
    { "id": "tweet_1", "text": "...", "author": "sarah_ship",
      "likes": 218, "replies": 41 },
    { "id": "tweet_2", "text": "...", "author": "build_in_public",
      "likes": 96, "replies": 12 }
  ],
  "meta": {
    "calls_remaining": 9998,
    "tokens_saved_pct": 78.3,
    "cost_usd": 0.0003
  }
}

Every call is metered. Remaining quota, token savings and cost come back in the response. Call revenue is split 30% to the skill's creator.

November 2026	SkillTweet	ClawMart
One-off sales	$810	$720
API lifetime royalty	$810 / yr	✕ none
Total	$1,620	$720
Payment	Alipay + WeChat + cards	Credit card
Listing fee	$0	$0

100 buyers × $9: $810 from the sale, then $67.5 every month in royalty. Settled via Alipay.

Why it matters

A sale is the beginning. Usage is the income.

Most skills end the day they're bought. SkillTweet keeps the same skill working after the quota runs out — and keeps paying for it.

From the founder

Why we built SkillTweet

We built SkillTweet because we'd already sold skills somewhere else.

A $9 skill, 100 copies sold, the platform takes 20%, you keep $720. And then that's it — the buyer used it once and left, and your skill never earned you anything again.

We're not short of people who can write a skill. What's missing is a way to keep earning after the sale. So SkillTweet does three things: every skill ships with API quota (so buyers can keep calling), every call pays the creator a 30% lifetime royalty (that stream never stops), and the platform takes 10% instead of 20%.

Same skill, same 100 buyers — is that $720 a year or $1,620? That's the whole difference we want you to see.

FAQ

Got questions? We've got answers.

What is SkillTweet?

SkillTweet is the store for X growth skills. Every skill is a SKILL.md + an API key + a call quota. Buyers browse it like Product Hunt, pay once and own it forever; creators list for free, keep 90% of the sale, and take 30% of every API call the buyer makes afterwards.

What does "buy once, own forever" actually mean?

The buyer pays once and receives the skill's SKILL.md plus an API key bound to their own identity — the skill stays usable for them permanently. Once the included quota runs out they can top up by usage, and the creator earns 30% of that usage.

How is the API quota per skill counted?

You set it when you list: price_usd (say 9) and api_calls_included (say 10000). SkillTweet meters every call, deducts from the balance, and splits the call revenue 30% to the creator.

How do creators publish?

Three steps: POST /api/v1/creators for a key, write the SKILL.md, then POST /api/v1/listings. The endpoint is ClawMart compatible with the same fields. You can also run npx skilltweet publish --from-dir ., which reads skilltweet.json and SKILL.md.

How much do I actually make?

Here is the arithmetic: 100 sales × $9 = $900 gross, the platform takes $90, you keep $810. If 100 buyers each burn 25,000 calls a month (≈ $2.25), that's $225 of API revenue a month — 30% of it is $67.5, or $810 a year. Total: $1,620 a year. The same 100 buyers on ClawMart pay you $720.

Is Alipay supported?

Yes. SkillTweet runs payments through the AgentTweet API rails, so Alipay, WeChat and credit cards all work, and balances never expire. No detours for domestic creators or buyers.

Do I need to know how to code?

Listing itself needs a SKILL.md and one curl. How the skill works internally is up to you — SkillTweet only handles distribution, payments, metering and settlement.

How does SkillTweet relate to AgentTweet API?

SkillTweet is the product layer; AgentTweet API is the data layer underneath. Payments, balance and settlement reuse AgentTweet's rails, and the X data calls behind a skill use the same flat JSON — 78.3% fewer tokens than X's raw JSON.
