DOC: install index url missing from high level doc and incorrect docstring:

micropip/micropip/_commands/install.py

Lines 96 to 98 in e107d89

	- The index URL should support the
	`JSON API <https://warehouse.pypa.io/api-reference/json/>`__ .

state that index "should support json api", as far as I can tell this is not true as we can see that Transation will use query_package:

micropip/micropip/package_index.py

Lines 262 to 284 in e107d89

	_fetch_kwargs["headers"].setdefault(
	"accept", "application/vnd.pypi.simple.v1+json, */*;q=0.01"
	)
	if index_urls is None:
	index_urls = INDEX_URLS
	elif isinstance(index_urls, str):
	index_urls = [index_urls]
	for url in index_urls:
	if _contain_placeholder(url):
	url = url.format(package_name=name)
	else:
	url = f"{url}/{name}/"
	try:
	metadata, headers = await fetch_string_and_headers(url, _fetch_kwargs)
	except OSError:
	continue
	content_type = headers.get("content-type", "").lower()
	parser = _select_parser(content_type, name)
	return parser(metadata)

micropip/micropip/package_index.py

Lines 80 to 88 in e107d89

	def from_simple_html_api(data: str, pkgname: str) -> "ProjectInfo":
	"""
	Parse Simple HTML API response
	https://peps.python.org/pep-0503
	"""
	project_detail = from_project_details_html(data, pkgname)
	name, releases = ProjectInfo._parse_pep691_response(project_detail) # type: ignore[arg-type]
	return ProjectInfo._compatible_only(name, releases)

which does support simple API.

(I have not tried though).

I think mentioning index could also be added in the pyodide documentation itslef in adiition to direct URLS:

Thanks. You are right. micropip now support Simple APIs (both HTML and JSON). Could you open a PR?

[Carreau]

Yes, I can send a pr a bit later. I'll try to do both one here, and on Pyodide to document it.
