Hey there, probably a bad idea, if so please disregard and close the request!
At the moment, I can reproduce this in TiTiler for an input COG using the |

@jo-chemla there is no such thing as bad idea! It's already possible 😅, instead of passing a simple url (e.g see #555 (comment) |

Sorry I think I got excited too quickly - before really decoding the url param with the wmts string. What I'd actually like to merge/crop are TMS/XYZ tiles with url like I don't know lots of ways to transform a TMS url to a WMTS capable server - one is using mapproxy with the below config file 1 for reference, but this would defeat the purpose of a pure client-side TMS/XYZ tiles merger/cropper. So, by digging a bit the list of gdal raster drivers, I found the TMS mini-driver within the WMS driver. So I tried to use the following url, URL-encode it, and use it as the url param of the TiTiler crop endpoint, with no luck atm. Do you think I'm stepping in the right direction? Note the WMS strings are these of the gdal WMS driver example here for osm and there for google

Hi again, For standard TMS servers:: URL-encode this XML string: https://titiler.xyz/cog/crop/-110,-70,110,70.png?url=<GDAL_WMS><Service name='TMS'><ServerUrl>http://example.com/tileset1/${z}/${x}/${y}</ServerUrl></Service><DataWindow><UpperLeftX>-20037508.34</UpperLeftX><UpperLeftY>20037508.34</UpperLeftY><LowerRightX>20037508.34</LowerRightX><LowerRightY>-20037508.34</LowerRightY><TileLevel>18</TileLevel><TileCountX>1</TileCountX><TileCountY>1</TileCountY><YOrigin>top</YOrigin></DataWindow><Projection>EPSG:3857</Projection><BlockSizeX>256</BlockSizeX><BlockSizeY>256</BlockSizeY><BandsCount>3</BandsCount><Cache /></GDAL_WMS>Similar than for a WMS compliant server: |

@MisterTiago can you open a new issue in rio-tiler repo The problem is that you're trying to read a part that intersect with the dataset boundary which will fail the test here: https://github.com/rasterio/rasterio/blob/fd4163d4b59ac628b2ed596f6828173baf8f25a3/rasterio/windows.py#L319-L324 called here https://github.com/cogeotiff/rio-tiler/blob/main/rio_tiler/reader.py#L441 |

@jo-chemla there is no such thing as bad idea!
It's already possible 😅, instead of passing a simple url (e.g
{endpoint}/tilejson.json?url=cog.tif) you can pass a GDALwmtsstring: https://titiler.xyz/cog/crop/-69.99510242702613,41.85313673098173,-69.99038118408833,41.857529724573766.png?url=WMTS%3Ahttp%3A%2F%2Ftitiler.xyz%2Fcog%2FWMTSCapabilities.xml%3Furl%3Dhttps%3A%2F%2Fnoaa-eri-pds.s3.amazonaws.com%2F2022_Pre_Event%2FEC2201a_OB_N_RGB%2FEC2201a_OB_N_C0700000w415145n.tif%26bidx%3D1%26bidx%3D2%26bidx%3D3%26tile_format%3Dpng&unscale=false&resampling=nearest&max_size=128&return_mask=truesee #555 (comment)
