Go’s strong standard library and concurrency model make it a solid fit for payment middleware and facilitators that must verify thousands of payments per second. These projects bring the x402 pay-per-request flow to Go HTTP servers and clients.
Below are the Go x402 and agent-payment libraries in the directory.
The Go category right now
48 Go libraries are tracked here, together holding 13,572 GitHub stars. Attention is concentrated: 3 repositories account for the bulk of it, with nofx (12,595★) at the top, while the median project sits at 1★. Treat the tail as prior art and reference code rather than production dependencies.
Language mix: Go (77%) and Rust (4%). Repeat publishers matter in this category — go:github.com (7), gosuda (2), joelklabo (2) ship more than one project each. Most-used topics: golang, x402, ai.
Momentum check: 35% of these libraries saw a commit in the past quarter (9 in the past month alone), while 7 have been dormant for more than a year — activity is uneven — check the last-commit date before adopting. x402-go is the most recently updated repository in the group.
