NeverBounce
NeverBounce headlines a true PAYG model at $0.008/credit (1,000 credits for $8) plus a $49/mo Growth subscription and a sales-led Enterprise plan. Per-credit semantics are explicit, credits expire 12 months post-purchase, and developer docs are public. xpay could not verify a /.well-known manifest or a one-shot anonymous purchase 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.
- 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.
- A free tier exists, lowering the bar for an agent builder to prototype before committing budget.
- Some tiers are sales-led; the highest-capacity surfaces are not self-serve.
- 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 NeverBounce could lift its score
NeverBounce lands solidly at Verified. Two missing points: (1) publish /.well-known/ai-pricing.json declaring the per-verification $0.008 rate; (2) expose a Stripe Payment Link so an unauthenticated agent can buy 1k credits in one shot without account creation.
