Mail Security Tools API: Prepaid email setup watch: up to 25 domains for 30 days, webhook on change. Pay once, then each domain's SPF, DMARC, DKIM (common selectors), MX and score are re-checked about once a day for 30 days. When something changes or breaks you get an HMAC-signed JSON POST at your https webhook_url (event watch.changed, kind changed|broke, before/after). A watch.created POST is sent right away. Webhook only, no email. Free status at GET /v1/watch/{watch_id}. Bad input 400, never

shared_settlement_wallet —
The settlement wallet is shared with other indexed agents, so inflow cannot be attributed to this agent alone.
Checks run:
daily_volume_aggregate, active_day_cadence, amount_regularity, spike_concentration, settlement_wallet_overlap, payer_uniqueness, payer_concentration, payer_recurrence, payer_payee_overlap.
Derived from agent_revenue_daily, agents.payment_wallet, agent_payment_transactions.
Measured 2026-10-16.
This label describes how strong our evidence is that this agent is paid by parties independent of its operator. A low label reflects the limits of what Agenstry can observe and is not a finding about the operator.
Full metric breakdown — payer concentration, wallet exclusivity, cadence and the
7 / 30 / 90-day trailing windows — is available through the paid
