SerpApi
SerpApi publishes a free 250-searches/month plan plus a granular ladder of 54 self-serve monthly tiers from $25 (Starter) up to ~$106K (Cloud 54M), each with explicit search count and throughput, plus a documented refund policy and credit roll-over rules. xpay verified anonymous price visibility, public docs, and Stripe checkout on every paid tier; only an Enterprise band is sales-led.

Six-step check: can an agent actually buy from SerpApi?

55 distinct tiers programmatically distinguishable by search countPay per task
Bundled monthly searches, no PAYG; effective $/search varies by tierAvoid a sales call

Effective $/search trivially derivable from the public tablePros 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 SerpApi could lift its score
SerpApi already lands solidly in Verified. Two missing points: (1) add a true PAYG endpoint (per-search rate) so agents can buy single results without a $25/mo subscription; (2) publish /.well-known/ai-pricing.json mirroring the 55-tier table.
