x402 turns HTTP 402 into a working payment handshake: price one invocation, settle it on-chain, end the relationship. What I think it is for, what it is not, a live reference implementation for agents and humans, and a Terraform module that adds it to any CloudFront distribution.

User-agents are claims and fingerprints are inference. OpenAI, Cloudflare, and DuckDuckGo are already signing their requests — I captured them at the edge and verified the signatures against each signer's own published keys.

How to capture TLS fingerprints at the CloudFront edge, route them through a serverless pipeline, and query them in Athena — using a CloudFront Function, a bash Lambda, SNS, Firehose, and S3.

User-Agent strings are trivially forged. TLS handshakes are not. How JA4 fingerprinting combined with ASN classification exposes distributed scraper clusters that look exactly like real browsers.

Raw requests are interesting, but how do we distinguish crawlers, retrieval systems, previews and humans?

Building a Visibility Layer for a Static Website with CloudFront, Athena and Grafana

Analyze web traffic with composable shell functions and goaccess. Separate humans from bots, track search traffic, measure LLM consumption — then export to Grafana.

Scrape AWS Lambda runtimes, cache at the edge, serve as JSON. A shell script, a CloudFront behavior, and a cron-free refresh strategy — the pattern, end to end.
