POST /verify-presence
unprobed
PRESENCE tier (deterministic, no LLM): confirms the claimed value appears on the live page — it does NOT confirm the value is the right answer to the question. Positive verdict is "present", never "pass"; check_type web_field_presence_v1. For full verification use /verify. First 100 checks per client are free: resend with header X-Use-Free-Allowance: yes and no payment to use them.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
