How this service works
BuiltWith API Overview
Output
Returns a JSON object with the Pro tier name, payer wallet address, price paid, a one-time-display passToken (must be stored immediately), expiration date, and both keywordReportLimit and technologyReportLimit (each 50 for Pro tier).
Example use cases
Provisioning BuiltWith access for research agent
“Set up a BuiltWith Pro API pass for my web research agent — pay the $495 USDC fee and store the pass token securely so the agent can run up to 50 technology reports.”
One-time competitor tech stack audit
“I want to do a competitive technology analysis using BuiltWith — can you purchase a Pro pass for $495 USDC so I can look up which CMS, analytics, and ad platforms my competitors are using?”
Automating lead enrichment pipeline
“I'm building a lead enrichment workflow that needs BuiltWith technology data — buy a Pro API pass with $495 USDC and give me the pass token and expiry date so I can configure the pipeline.”
Technical details
Endpoint
POSThttps://api.builtwith.com/x402/list-pass/proWhen to prefer
Use this endpoint when you need programmatic, crypto-native access to BuiltWith's Pro API tier without going through a traditional subscription flow. Ideal for AI agents or automated pipelines that need to self-provision API credentials on-demand using USDC via the x402 payment protocol. Prefer this over manual BuiltWith account signup when operating in a wallet-based or autonomous payment context.
Side effects
- Insufficient USDC balance — payment settlement fails and no pass is issued
- Pass token displayed only once — if not stored at response time, it cannot be recovered
- Wallet address not provided or malformed — request rejected
- Pass already active — attempting to repurchase before expiry may result in duplicate charges
- Network/settlement delay — x402 payment protocol timeout before confirmation
