Get technology adoption trends for any named technology via BuiltWith data, paid per call.
What it does
The BuiltWith Trends endpoint returns adoption trend data for a specified web technology (e.g. "Shopify", "Next.js", "React"). It is one of several BuiltWith endpoints exposed through the Locus MPP (Micropayment Protocol) gateway, which wraps the BuiltWith API behind per-call crypto payments settled on Tempo L2 in pathUSD.
To use this endpoint, send a POST request with a JSON body containing a required `TECH` field specifying the technology name. Each call costs 35,000 base units of pathUSD (pathUSD uses 6 decimals), which works out to $0.035 per request. Payment is handled via the MPP charge flow — the endpoint returns a 402 challenge that your MPP-compatible client resolves before the request is fulfilled.
This endpoint is part of a broader BuiltWith suite available at the same gateway, including domain lookups, technology lists, relationship mapping, company-to-URL resolution, product search, trust signals, keywords, redirects, recommendations, and a free summary tier. The Trends endpoint specifically focuses on historical and current adoption metrics for technologies across BuiltWith's index of 100M+ websites. No response schema is documented in the OpenAPI spec, so the exact shape of the returned trend data is not confirmed from the available material.
Capabilities
Use cases
- —Track adoption growth or decline of a specific web technology over time
- —Compare technology market share trends for competitive analysis
- —Monitor emerging frameworks or platforms gaining traction across websites
- —Feed technology trend data into automated market research pipelines
Fit
Best for
- —Agents needing programmatic access to web technology trend data without API key management
- —Competitive intelligence workflows tracking technology adoption
- —Market research on web technology ecosystems
Not for
- —Looking up the tech stack of a specific domain (use the /builtwith/domain endpoint instead)
- —Finding which sites use a specific technology (use the /builtwith/lists endpoint instead)
- —Free or high-volume bulk trend analysis (each call costs $0.035)
Quick start
curl -X POST https://builtwith.mpp.paywithlocus.com/builtwith/trends \
-H "Content-Type: application/json" \
-d '{"TECH": "Shopify"}'Example
Request
{
"TECH": "Shopify"
}Endpoint
Quality
The OpenAPI spec provides a clear request schema and pricing, and the endpoint is part of a well-structured MPP gateway. However, the probe did not capture a 402 challenge on HEAD/GET (the endpoint requires POST), no response schema is documented, and no example responses are available. The crawl pages all returned 404, yielding no supplementary documentation.
Warnings
- —Probe used HEAD/GET but this endpoint only accepts POST — the 404 does not mean the endpoint is down, just that the wrong HTTP method was used
- —No response schema documented in the OpenAPI spec; the shape of trend data returned is unknown
- —Currency address 0x20c000000000000000000000b9537d11c60e8b50 is assumed to be pathUSD with 6 decimals based on the Tempo settlement method; if this assumption is wrong the price calculation would differ
