Attom Data Plans Pricing
ATTOM does not publish transparent per-endpoint list pricing for its API. The documented public entry point is a 30-day free trial (register at cloud.attomdata.com for immediate API access); production access is sold as custom subscriptions negotiated with ATTOM sales. Subscriptions are commonly scoped by the datasets/endpoints licensed, the volume of monthly API calls, geographic coverage, and delivery method, with a per-minute call ceiling (ATTOM documents a 200-calls-per-minute limit) plus a monthly call allowance per plan. Third-party reports put entry-level API access in the low hundreds of dollars per month, but ATTOM only publishes list pricing for its Property Navigator end-user tool, not the API - treat all dollar figures as unreconciled until confirmed with ATTOM.
Attom Data Plans Pricing is the machine-readable pricing-plan profile for ATTOM on the APIs.io network, conforming to the API Commons Plans specification.
It defines 3 plans, covering trial, paid, and enterprise tiers, with named plans including Free Trial, API Subscription (Custom), Enterprise / Bulk & Custom Delivery.
Tagged areas include Property Data, Real Estate, Valuation, and Plans.
