One focused program per file, written for readability. They build with the default configure (COFETCH_BUILD_EXAMPLES=ON) and hit public echo endpoints, so they need network access to run.

example	shows
example_hello.cpp	the smallest program: one GET, one callback
example_fluent.cpp	building a POST with the chainable setters
example_coroutine.cpp	dependent requests in linear code (C++20 `co_await`)
example_future.cpp	`std::future` style: start, drive, `get()`
example_sync.cpp	wrapping the async client in a blocking `SyncClient` facade
example_concurrent.cpp	20 requests in flight on one thread
example_errors.cpp	transport errors vs HTTP error statuses
example_cancellation.cpp	a time budget per request with `asio::cancel_after`
example_redirects.cpp	3xx as-is by default; `follow_redirects()` to chase them
example_http2.cpp	requests multiplexed over one HTTP/2 connection; opting a request back to HTTP/1.1
example_tls.cpp	https out of the box; TLS knobs via the `.curl()` escape hatch
example_compression.cpp	gzip/brotli responses arrive already decoded
example_keepalive.cpp	connection pooling: the second request skips the handshake
example_reactors.cpp	`run()` vs busy-`poll()` vs a foreign epoll loop; io_uring build
