GET /v1/status

live

Is a vendor down right now? Current outage status for one SaaS vendor. $0.01 USDC on Base per call. Returns status, active-incident summary, last-checked time, source URL and freshness fields, read live from PulseWatch. Unknown vendors return 404, not charged. Don't use this for past incidents; use /v1/incidents.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
