Enrichment APIs — agent-ready pricing benchmark

Per-credit billing exists but most vendors gate paid plans behind sales — partial agent-readiness.

5 Approaching Agent-Ready
2 Partially Agent-Ready
3 Not Agent-Ready Yet
#1
Hunter
hunter.io · Enrichment APIs
78
/ 100
Approaching Agent-Ready
Hunter exposes a complete public price table (Free, Starter $34, Growth $104, Scale $209, Enterprise) with explicit per-credit accounting (1 credit per email, 0.5 per verification) plus a standalone bulk credit-pack flow visible on the same page. The pricing page also surfaces an MCP integration row alongside its public API. xpay could not verify a /.well-known manifest or anonymous one-shot purchase, leaving 18 points unclaimed.
#2
People Data Labs
peopledatalabs.com · Enrichment APIs
71
/ 100
Approaching Agent-Ready
PDL publishes Free, Pro starting at $98/mo for 350 records, and Enterprise (custom) with a transparent volume-based discount narrative on the page. Records-retrieved is the metering unit and is fully exposed; docs are public. The Pro entry sits above the $20 'low minimum' threshold, so the Low/no minimum dimension is partial. Enterprise tier is sales-led.
#3
Snov.io
snov.io · Enrichment APIs
70
/ 100
Approaching Agent-Ready
Snov.io publishes a six-tier ladder (Trial, Starter $29.25, Pro S/M/L, Custom Ultra) with per-credit pricing visible (~3.9¢ on Starter, ~0.9¢ on Pro M) and a public REST API + Webhooks + Email Finder API. Five tiers are self-serve. xpay could not verify a machine-readable pricing manifest or an unauthenticated one-shot purchase path.
#4
Apollo.io
apollo.io · Enrichment APIs
68
/ 100
Approaching Agent-Ready
Apollo publishes four named tiers (Free, Basic $49, Professional $79, Organization $119) with per-credit semantics openly documented (1 credit per email, 8 per phone, 1 per AI research run). Three tiers offer a 'Buy now' self-serve checkout flow, and the Free plan grants 900 credits per year with no card. xpay could not verify a one-shot anonymous PPU path or a machine-readable pricing manifest, so two dimensions are partial.
#5
Lusha
lusha.com · Enrichment APIs
68
/ 100
Approaching Agent-Ready
Lusha publishes a five-tier ladder (Free, Starter $37.45, Pro $52.45, Premium $299.95, Scale custom) with an explicit credits breakdown table mapping each action to a numeric cost. API access is gated to Pro and above with rate limits, and docs are public. xpay could not verify an unauthenticated one-shot purchase or a machine-readable pricing manifest.
#6
RocketReach
rocketreach.co · Enrichment APIs
60
/ 100
Partially Agent-Ready
RocketReach publishes three numeric tiers (Essentials $33, Pro $75, Ultimate $142) plus an Enterprise sales-led plan, with self-serve checkout backed by Stripe/PayPal/Braintree. Quotas are denominated in monthly lookups and annual exports rather than a per-call dollar rate, which is observed as a softer match for the metered-pricing dimension. xpay could not verify a machine-readable pricing manifest or one-shot anonymous purchase.
#7
ContactOut
contactout.com · Enrichment APIs
56
/ 100
Partially Agent-Ready
ContactOut lists Free, Email $25/mo (annual), Email+Phone $49/mo (annual), and a sales-led Team/API tier with discounted promo strikethroughs visible. API access lives behind the Team tier and the API documentation page is referenced but credentialing details require sales contact. Quotas are export-based rather than per-call $$. Self-serve covers the two consumer tiers.
#8
ZoomInfo
zoominfo.com · Enrichment APIs
15
/ 100
Not Agent-Ready Yet
ZoomInfo's pricing page lists six product packages (Professional, Copilot Advanced, Copilot Enterprise, Marketing Demand, ABM Lite, ABM Enterprise) with feature deltas but no monetary numbers; every CTA routes to a 'Get Pricing' form or 'Talk to Sales'. The page describes that pricing depends on licenses, credit usage, and add-ons but does not publish per-credit rates. API documentation is reachable without login.
#9
FullContact
fullcontact.com · Enrichment APIs
8
/ 100
Not Agent-Ready Yet
The /pricing/ URL redirects to a 'Get In Touch' contact form requesting first name, company, country, job function and use case. xpay could not surface any tier names, numeric prices, or self-serve flow on the public page. Developer documentation at docs.fullcontact.com is publicly browsable, which is the sole positive signal.
#10
Clearbit
clearbit.com · Enrichment APIs
5
/ 100
Not Agent-Ready Yet
Following Clearbit's acquisition by HubSpot, the legacy /pricing URL now redirects to a HubSpot-branded landing page that does not display tier numbers, per-unit rates, or a self-serve purchase path. xpay could not verify any agent-purchasable plan from the public page; the historical Clearbit API documentation referenced under dashboard.clearbit.com requires authentication to inspect.
