Diffbot
Diffbot publishes Free / Startup ($299) / Plus ($899) / Enterprise tiers on a public page with an explicit credit-cost matrix (1 credit/page Extract, 25/Knowledge-Graph entity, etc.) and a documented overage rate at the plan's per-credit price. xpay verified self-serve checkout on the two paid public tiers and a generous no-card free tier, though the Startup floor at $299/mo lifts the minimum-commitment score below pass and no machine-readable manifest is published.

Credit-cost table per activity displayed on /pricingPros and cons for AI agents
Observational summary written by xpay from the signals captured on 2026-05-03. 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 Diffbot could lift its score
Diffbot already lands in Verified. Three missing points: (1) introduce a sub-$50 PAYG entry below the $299 Startup floor; (2) publish /.well-known/ai-pricing.json mirroring the credit table; (3) enable an anonymous Stripe-link purchase path for one-shot agent buys.
