TRY FIRST · INSPECT TERMS · NO AUTO-SPEND

Try before you buy.

Seven useful AI-agent jobs with a no-spend inspection path first. Check what the tool does, whether it is ready, what it costs, and where the evidence comes from before authorizing any x402 payment.

Transparent payment rule: a 402 means payment is required. It is not a purchase and it is not settlement proof. The fresh target PAYMENT-REQUIRED challenge is the authority for exact x402 terms. The caller controls spending.

WHY THIS IS DIFFERENT

Useful before payment, explicit after payment.

1 · InspectReadiness, contract, scope and limitations first.

2 · ChallengeA 402 exposes exact current terms without proving a purchase.

3 · AuthorizeThe caller decides whether the price fits its own spending policy.

4 · VerifySettlement, successful delivery and acceptance remain separate evidence stages.
