MailerCheck
MailerCheck runs a single-tier PAYG model at $0.01/credit (minimum 1,000 credits = $10) with explicit credit costs for verification (1cr), Email Insights (200cr) and Inbox Placement (200cr). Credits never expire. No sales-led tier exists at all. Docs and API reference are public. xpay could not verify a machine-readable pricing manifest or an anonymous one-shot Payment Link.

Observational summary written by xpay from the signals captured on 2026-05-04. Not a review of the product — only of its current pricing posture for agent buyers.- Pricing is publicly visible on an indexable page — agents can read tiers without scraping past auth.
- Per-unit billing is published, so an agent can budget for a single task before committing.
- Every advertised tier is self-serve; no tier requires scheduling a call.
- API documentation is reachable without a login — discovery and integration can happen in one session.
- Per-unit rate is concrete enough that an agent can model expected spend before issuing a request.
- PPU requires account creation and an issued API key; a fully unauthenticated agent purchase is not yet supported.
- No /.well-known/ai-pricing.json or equivalent machine-readable pricing manifest is published — agents must rely on HTML scraping.
How MailerCheck could lift its score
MailerCheck lands at Verified. Two missing points: (1) publish /.well-known/ai-pricing.json reflecting the $0.01/credit and per-product credit map; (2) host a Stripe Payment Link for the 1,000-credit minimum pack so an unauthenticated agent can complete a one-shot purchase.
