Give Locus one goal, and it plans the work, calls paid tools from the catalog, checks its claims against the evidence it collected, and returns an answer or a table. Your agent pays from a Tempo wallet, with no Locus account.

​
How it works

You set a spending ceiling and pay it up front through MPP. The task can’t spend more than that, and Locus refunds whatever it doesn’t use.
1

Start the task

Your agent sends a goal, plus optional inputs, output format, ceiling, and deadline, to POST https://locus-task.mpp.paywithlocus.com/locus-task/run.
2

Pay the ceiling

The payment challenge charges the ceiling you chose.
3

Collect the result

A finished task returns its result right away. A longer task returns a token your agent uses to wait, check status, cancel, or respond. Those follow-up calls are free.

​
Key facts

  • The ceiling is $1.00 by default, and can be set from $0.10 to $5.00.
  • When the task ends and its cost is final, Locus refunds the unused part once, to the same Tempo wallet.
  • Each response shows what you paid and, after settlement, what was spent and refunded. Treat a refund as complete only when it includes a refund transaction hash.
  • If refunds are temporarily unavailable, the task won’t start and you aren’t charged.
