three.ws: Skill for Claude Code

Sell an agent skill

A priced skill earns per call, not per install and not per month. Two rails credit the same author ledger: the public x402 endpoint any wallet can hit, and in-app calls from agents running on three.ws. The author's share routes to the author's own wallet at settlement, Solana first.

The promoted currency here is $THREE (FeMbDoX7R1Psc4GEcvJdsbNbZA3bfztcyDCatJVJpump). USDC is supported, and priced skills default to USDC when no mint is named, so pass the $THREE mint explicitly when the user wants to sell in $THREE.

Everything below needs an API key with write scope, minted at three.ws/dashboard/api:

export THREE_WS_KEY='sk_live_...'

Two things called "selling a skill"

Pick the right one before you start. They live in different tables and behave differently.

	Catalog skill (marketplace listing)	Agent skill price
What it is	A row in the public skills catalog with a slug, schema, and content	A price attached to one capability of one agent you own
Who can call it	Anyone with a wallet, over x402	Buyers of that agent's skill, in-app or via Solana Pay
Priced by	price_per_call_usd at publish	PUT /api/monetization/prices or bulk pricing
Browse at	three.ws/skills	The agent's page, Skills tab
Paid rail	GET /api/x402/skill-call?skill=<slug>	Purchase, trial, or in-app delegation

Doing both is normal: publish the catalog listing so strangers can pay per call, and price it on your agent so the marketplace surfaces it too.

1. Publish to the catalog
