How much do BuiltWith plans and API credits cost?

BuiltWith sells two things: API credits for programmatic lookups, and plans for building lead lists in its web app. Plans also include API credits, and those credits accumulate month to month. Figures from builtwith.com on November 10, 2026.

What does each BuiltWith endpoint cost?

Costs come from BuiltWith’s API reference. Most endpoints use 1 credit per lookup, which is about $0.0495 on pay-as-you-go credits. Prices checked November 10, 2026.

What does each BuiltWith endpoint cost?
Endpoint	Cost
Domain API (full technology profile)	1 credit per domain
Free API (group counts)	Free
Trends API	Free
Lists API (sites using a technology)	Needs a plan from $295 a month

What does it cost to look up the tech stack of 1,000 domains?

With pay-as-you-go credits, 1,000 Domain API lookups use half of a $99 pack, about $49.50 of credit. The rest never expires. On the Team plan used in full, the same 1,000 lookups cost about $9.95.

Failed lookups use no credits on BuiltWith. If you only need technology group counts, the Free API returns them at no cost. Prices checked November 10, 2026.

What are the catches in BuiltWith pricing?

BuiltWith is flexible to cancel, but check these terms.

The Lists and Keyword Search APIs need a plan. Pay-as-you-go credits do not unlock them.
Plans have a minimum term of 1 month, or 1 year on yearly billing. A canceled plan stays active to the end of the term.
The API allows 10 requests a second and 8 at once. More returns a 429 error.
The Trust API uses an extra credit when you ask for a live check.
A Domain API call can look up 16 domains, and each domain costs 1 credit.
Basic’s 2,000 monthly credits cost about $0.15 each. Buy API credits alone if you do not need lists.

What does Locus Pro add for BuiltWith lookups?

Locus Pro offers BuiltWith’s Domain, Lists, Relationships, Trends, Free and other APIs as per-call endpoints. Your agent pays from one prepaid credit balance shared with Apollo, Hunter and other providers, with no BuiltWith account, credit pack or plan. That includes Lists, which BuiltWith itself sells only with a plan.

Your agent sees the price before each call and can cap it. A monthly hard limit stops new calls once you reach it. On Enterprise, you can bill your own customers for the lookups their agents run.

Which BuiltWith option should you choose?

Pick by how often you need lists and how many domains you look up.

Thousands of lookups a month: Pro or Team. At full use, Team costs about $0.01 a lookup.
Occasional domain lookups without lists: a $99 credit pack, since the credits never expire.
An agent that needs a lead list for one technology now and then: Locus Pro’s Lists endpoint, billed per call.
An agent that mixes BuiltWith with contact data from Apollo or Hunter: one Locus balance for all of them.
Technology group counts and adoption trends only: BuiltWith’s Free and Trends APIs, which use no credits.

Frequently asked questions

Does BuiltWith have a free API?

Yes. The Free API returns technology group counts for a site, and the Trends API returns adoption trends. Neither uses credits. Single site lookups on builtwith.com are also free.

Do BuiltWith API credits expire?

No. Pay-as-you-go credits do not expire, and credits included with a plan accumulate month to month. Failed lookups do not use a credit.

What is the BuiltWith API rate limit?

Up to 10 requests a second and 8 concurrent requests per key. Going over returns a 429 error. BuiltWith offers dedicated endpoints for higher throughput by arrangement.

Can I get a one-off BuiltWith report?

BuiltWith suggests signing up for Basic, pulling the report and canceling. The minimum term is still 1 month, so a one-off list costs at least $295.
