Blossom /media endpoint interface is not conforming to specification

[mrkvon]

It looks like blossom.getOptimizedBlob() defined in

ndk/blossom/src/blossom.ts

Lines 400 to 456 in e51b54c

	/**
	* Gets an optimized version of a blob
	* @param url The URL of the blob
	* @param options Optimization options
	* @returns The optimized blob response
	*/
	public async getOptimizedBlob(url: string, options: BlossomOptimizationOptions = {}): Promise<Response> {
	try {
	// Parse the URL and extract relevant parts
	const urlObj = new URL(url);
	const baseUrl = `${urlObj.protocol}//${urlObj.host}`;
	const hash = urlObj.pathname.split("/").pop();
	if (!hash) {
	throw new NDKBlossomOptimizationError("Invalid URL, no hash found", "BLOB_NOT_FOUND", url);
	}
	// Construct the media URL
	let mediaUrl = `${baseUrl}/media/${hash}`;
	// Add optimization parameters as query string
	const params = new URLSearchParams();
	for (const [key, value] of Object.entries(options)) {
	if (value !== undefined) {
	params.append(key, value.toString());
	}
	}
	if (params.toString()) {
	mediaUrl += `?${params.toString()}`;
	}
	// Fetch the optimized blob
	const response = await fetchWithRetry(mediaUrl, {}, this.retryOptions);
	if (!response.ok) {
	throw new NDKBlossomOptimizationError(
	`Failed to get optimized blob: ${response.status} ${response.statusText}`,
	"SERVER_REJECTED",
	url,
	);
	}
	return response;
	} catch (error) {
	if (error instanceof NDKBlossomOptimizationError) {
	throw error;
	}
	throw new NDKBlossomOptimizationError(
	`Failed to get optimized blob: ${(error as Error).message}`,
	"SERVER_UNSUPPORTED",
	url,
	error as Error,
	);
	}
	}

is incorrect or uses some non-standard endpoint.

BUD 05 defines PUT /media, which seems to work similar to PUT /upload. OTOH, endpoint GET /media/<SHA256> used by getOptimizedBlob is not specified anywhere, afaics.

Has it been tested against existing Blossom servers, does it work, is it some non-standard behaviour?

PUT /media would be a very useful feature. Some servers may have capabilities like metadata removal, unlike PUT /upload which saves data as-is.

Actual behavior

blossom.getOptimizedBlob() uses non-standard endpoint.

Expected behavior

Standard endpoint PUT /media is available for upload via some method in this library.
