Agent Skills · Pay Skill

Pay-skill listings are skills whose point is a charge: a metered API, a checkout, a paid tool the agent is told to call. Read them as billing questions that happen to include a prompt. The convenience is real only after you know who charges what, and how you shut it off.

Before install, name the merchant, the unit of billing, and the key that will be used. If the prompt says to paste a secret into the chat, stop. Put the key in the agent's secret store or do not continue. A production key with a spend cap of "unlimited" is not a trial. Create a key with a small quota and revoke it the same day if the output is wrong. The stop list starts with this case because it is easy to skip when the demo is a single click.

A paid skill is not how you buy a higher rank on AI Agent Hub. Our sort is mechanical. How ranking works and the corrections guide both say we do not sell placement. If a card implies that paying unlocks a badge on this site, the card is confused or misleading. Tell us.

Separate the publisher's fee from any model fee your agent already incurs. You can be billed twice for one run: once by the skill's API and once by the model that read the prompt. Write both down before you leave the skill installed overnight. Overnight plus a retry loop is how a small per-call price becomes a surprise.

If a free skill on another shelf does the same job, use that until you know you need the paid call. Payment is not quality. It is an invoice. Keep the receipt and the revoke button closer than the install prompt.
