The wasi:http/incoming-handler interface relies on upstream standardized WIT interfaces (specifications on how requests are structured, etc).
To pull those third party (Bytecode Alliance maintained) WIT interfaces, one tool we can use is [wkg][wkg]:
wkg wit fetch
Once wkg has finished running, you should find your wit folder populated with a new deps folder alongside component.wit:
wit

├── wasi-clocks-0.2.6

├── wasi-http-0.2.6

├── wasi-io-0.2.6
