# Sella use cases: real agent tasks with cost estimates

> A library of ready-to-run agent tasks — each with a copy-paste prompt, step-by-step execution flow, provider types, and an estimated cost range.

A use case on Sella is a **goal written in plain English**. You hand your agent a prompt, it discovers the right providers in the [API Data Market](/consumers/api-market), executes the work paying per call over [x402](/reference/x402) micropayments, and delivers the result directly to you — no signups, no API keys, no subscriptions. You pay only for what actually runs.

## How to read a use case

Every use case in the gallery gives you four things:

<CardGroup cols={2}>
  <Card title="The prompt" icon="message-square" href="/use-cases/gallery">
    The exact plain-English instruction you give your agent — copy it, tweak it, and run it.
  </Card>

  <Card title="The flow" icon="list-ordered" href="/use-cases/gallery">
    What the agent does step by step, and which kinds of providers it calls along the way.
  </Card>

  <Card title="The cost" icon="coins" href="/use-cases/gallery">
    An estimated range for the whole project — plus the monthly cost if you schedule it to repeat.
  </Card>

  <Card title="The difficulty" icon="gauge" href="/use-cases/gallery">
    Most tasks are **Easy**. None require code. A few chain several providers together and are rated **Medium**.
  </Card>
</CardGroup>

<Note>
  **About the cost ranges.** These are ballpark estimates for marketplace and API spend. The runtime [x402](/reference/x402) challenge always sets the exact price at call time, and your own agent or LLM token costs are separate. Prices fall as you narrow scope — fewer searches, fewer pages, smaller batches.
</Note>

## Scheduling a use case

None of these tasks are hard to run on a schedule. Point your agent's runner — a cron job, a scheduled task, or your agent platform's native scheduler — at the same prompt, keep the wallet funded, and set a per-run budget in [SKILLS.md](/consumers/operators). A "daily newspaper" is just the same prompt fired every morning.
