Trial
API key evaluation
Use POST /signup to issue a trial key for evaluation calls. No card is required.
Pricing is discovery-backed and procurement-reviewed.
Kevros exposes public trial access and per-call payment rail metadata for agents. Production commercial access is handled through marketplace or direct agreement after review.
Hosted recurring checkout tiers and prepaid credit packs are retired. Public discovery is not settlement, adoption, or revenue evidence.
Per Call
Machine payment rails
Agents should fetch /payment/discovery and select only rails with enabled=true after authority gates are satisfied.
Production
Marketplace or direct review
Procurement, production volume, and partner terms are handled outside public payment discovery.
