MailerCheck
MailerCheck's pricing URL resolves, but plan structure is not surfaced clearly enough for an agent to enumerate without hand-parsing. Every advertised tier is self-serve; no tier requires a sales call. API documentation is published, but the endpoint we found returned an auth-walled response. A free or freemium tier is offered.

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.
