Both provide nationwide U.S. property data by API and bulk delivery. Realie is an agent-native, self-service property data API — Free tier, month-to-month plans at $50, $150, and $350, agent-first MCP + CLI on the same self-serve API key, and public docs — sourcing county assessor, recorder, and parcel records across 180M+ addresses · nationwide U.S. county coverage. Realie publishes ~20 ms average (docs.realie.ai). In Realie’s separate September 2026 benchmark (blog.realie.ai) on the same 100 properties across 25 states, ATTOM `/property/basicprofile` averaged 232.6 ms mean (minimum 108.5 ms, P90 325.0 ms). Verify ATTOM coverage, pricing, and latency from your own stack.
Realie and ATTOM both sell nationwide U.S. property records by API and bulk. The decision usually comes down to buying model, time-to-first-query, cost at your volume, and whether latency fits inside a live request path. This page states Realie specifics we can verify — including published Realie latency and a separate September 2026 ATTOM benchmark on the same property set — plus ATTOM commercial terms from their public site (always verify with ATTOM). For competitor coverage, contract terms, and performance outside this test, evaluate what ATTOM actually quotes you rather than a third-party summary.

Where Realie goes deeper
Agent-native access on self-serve API keys
Create an account, add a payment method, and generate an API key without a sales call. The free tier uses the same production dataset and endpoints as paid plans. Month-to-month plans are Free, $50, $150, and $350 — same fields on every tier.
Realie is agent-native: self-serve API keys work across REST, CLI, and MCP. Onboard agents via `/agents`, `/agents.md`, and `llms.txt`. Docs Mintlify MCP vs app `/api/mcp` — see docs.realie.ai for which surface matches your IDE workflow.
Published Realie latency vs September 2026 ATTOM benchmark
Realie publishes ~20 ms average on docs.realie.ai — a separate measurement from any vendor benchmark. Verify from your infrastructure when sizing live request paths and agent loops.
ATTOM `/property/basicprofile` on a 100-property test set across 25 U.S. states. Each property queried once; request order randomized; persistent HTTP session; connection warm-up excluded. ATTOM returned property for 100/100 requests. Observed September 2026; latency varies by network, load, query type, and geography. In that ATTOM-only test, mean latency was 232.6 ms (minimum 108.5 ms, P90 325.0 ms). Re-run from your region and with your query types before committing.
County public-records sourcing
Realie normalizes what county assessors and recorders publish: parcel identity and geometry, owner of record and mailing address, assessment and tax, sale and transfer history, mortgages, liens, and zoning — 180M+ addresses · nationwide U.S. county coverage. Data is for property research and analytics; not for FCRA-regulated credit, insurance eligibility, employment, or tenant screening decisions.
Where ATTOM goes deeper
Enterprise licensing and API pricing
Public site: trial then contact sales (no full public price card). ATTOM does not publish a full self-serve price card with monthly call quotas — contact sales for production pricing and contract terms. Teams on an existing ATTOM agreement may have negotiated bundles worth preserving.
Coverage and refresh in your counties
National coverage figures rarely settle a county-specific decision. Ask ATTOM for refresh cadence, field availability, and identifier formats in the counties you ship — then map those against your product requirements.
When to choose Realie vs ATTOM
| Scenario | Recommendation |
|---|---|
| You need to evaluate on a free tier this week without a sales call | Realie — self-serve signup with production API access |
| Latency-sensitive lookups run inside a live HTTP request | Realie — ~20 ms average vs ATTOM 232.6 ms in Sept 2026 benchmark; verify from your stack |
| You already have a negotiated ATTOM enterprise bundle you rely on | Stay on ATTOM until you map required fields; verify switch cost with ATTOM |
| You need MLS listings or active for-sale inventory | Neither vendor alone — add an MLS or listing provider; Realie is public records only |
| Cursor, Claude Code, or terminal agents need property lookups without custom wrappers | Realie — agent-first MCP + CLI on self-serve keys; verify ATTOM agent tooling with ATTOM |

FAQ
- Is Realie a drop-in replacement for ATTOM?
- For public-records use cases — parcel, ownership, assessment, tax, transactions, mortgage, lien, zoning — the data categories overlap. Map your required fields against both before switching, and confirm ATTOM specifics with ATTOM.
- Can I evaluate Realie without talking to sales?
- Yes. Sign up, add a payment method, generate an API key, and query the production dataset on the free tier.
- Does Realie offer bulk delivery as well as an API?
- Yes — nationwide, state-level, or county-scoped datasets delivered to AWS, Google Cloud, or Azure. Bulk is licensed separately from self-service plans.
- Does Realie include MLS listings?
- No. Realie is public-records data. If you need active for-sale inventory you need an MLS or listing provider in addition.
