Upload Coin Metadata
pumpfun_upload_metadataIdempotent
Upload coin metadata (name, symbol, description, image) to IPFS and get back a pump.fun-ready metadata URI. Call this before launching a coin: pass the returned uri to the launch-agent endpoint or the studio launch flow. Requires a valid bearer token (API key). Image may be a public HTTPS URL or a base64 data URI (max 10 MB). The returned uri is a permanent ipfs:// link; the call is idempotent for the same content.
