Should I use a vendor API or scrape public records?

It depends on your use case, risk tolerance, and the kind of data you need. Here’s the practical way to decide:

Use a vendor API if:

• You need reliability and consistent uptime
• The data has clear licensing/terms or you need commercial use rights
• You want lower maintenance and fewer breakages
• You need support, SLAs, documentation, or change notifications
• You care about compliance, auditability, and legal clarity

Consider scraping public records if:

• The data is truly public and no API exists
• You need one-off or experimental access
• The cost of a vendor is too high
• You can tolerate site changes, anti-bot measures, and maintenance
• You’ve checked that scraping is allowed by the site’s terms, robots rules, and applicable law

Key tradeoffs

Vendor API

Pros

• Stable, predictable format
• Easier integration
• Better legal/commercial clarity
• Often cleaner, enriched data

Cons

• Cost
• Rate limits
• Less flexibility
• Vendor lock-in

Scraping

Pros

• Can be cheaper initially
• No dependency on a vendor’s product decisions
• Useful when no API exists

Cons

• Fragile
• More engineering time
• Higher legal/compliance risk
• Harder to scale and maintain

A good rule of thumb

• If this is core to your business, use a vendor API unless there’s a strong reason not to.
• If it’s temporary, exploratory, or low stakes, scraping may be acceptable.
• If the records are public but sensitive, regulated, or used in decision-making, lean toward a vendor or official data source.

Questions to ask before deciding

1. How often do I need the data?
2. What happens if the source layout changes?
3. Do I need commercial usage rights?
4. Can I afford outages or inaccurate data?
5. What are the legal/contract terms?
6. Is there an official bulk download or open data feed?

If you want, I can help you choose for a specific source by comparing:

• cost,
• legal risk,
• maintenance burden,
• data quality,
• and speed to build.
