Search by Name, SMILES, InChI, InChIKey, etc. Return a list of found IDs (first 100). <span style="color: red; font-weight: bold;">This operation is deprecated and will be removed soon - use SimpleSearch instead.</span>
Get structure image in PNG format. <span style="color: red; font-weight: bold;">This operation is deprecated and will be removed soon - use GetCompoundThumbnail instead.</span>
Get record details: CSID, InChIKey, InChI, SMILES. <span style="color: red; font-weight: bold;">This operation is deprecated and will be removed soon - use GetCompoundInfo instead.</span>
Search by Name, SMILES, InChI, InChIKey, etc. Returns a list of found CSIDs ordered by the best match found (first 100 - please use AsyncSimpleSearch instead if you like to get the full list). Security token is required.
Search by Name, SMILES, InChI, InChIKey, etc results are in order of the best match found. Returns transaction ID which can be used to access search status and result. Security token is required.
Search by Name, SMILES, InChI, InChIKey, etc. and order the results by either CSID, Molecular Weight, Reference Count, Data Source Count, Pub Med Count or RSC Count. Returns transaction ID which can be used to access search status and result. Security token is required.
Search by SMILES or MOL. Returns transaction ID which can be used to access search status and result. Security token is required.
Search by SMILES or MOL. Returns transaction ID which can be used to access search status and result. Security token is required.
Search by SMILES or MOL. Valid values of the Threshold parameter are between 0 and 100. Returns transaction ID which can be used to access search status and result. Security token is required.
Search by intrinsic properties. Returns transaction ID which can be used to access search status and result. Security token is required.
Search by intrinsic properties and order the results by either CSID, Mass Defect (if searching by mass), Molecular Weight, Reference Count, Data Source Count, Pub Med Count or RSC Count. Returns transaction ID which can be used to access search status and result. Security token is required.
Search by chemical elements Returns transaction ID which can be used to access search status and result. Security token is required.

Search by LASSO. Input values for FamilyMin and FamilyMax should correspond to the short name of the relevant enzyme e.g. ACE (see http://www.chemspider.com/FullSearch.aspx for other values). Valid thresholdMin and thresholdMax should be between 0 and 0.99. Returns transaction ID which can be used to access search status and result. Security token is required.
Query asynchronous operation status. Requires transaction ID returned by Asynch<SOMETHING>Search operation. Security token is required.
Query asynchronous operation status, if the result is available a count of the records found is also included as well as a message describing how the record was found. Requires transaction ID returned by Asynch<SOMETHING>Search operation. Security token is required.
Returns the list of CSIDs found by Asynch<SOMETHING>Search operation. Security token is required.
Return a slice of the list of CSIDs found by Asynch<SOMETHING>Search operation. Returns full list if start = 0 and count = -1. If (start + count) > (# of results) all results starting at start position are returned. Security token is required.
Get compound thumbnail in PNG format. Security token is required.
Get record details (CSID, StdInChIKey, StdInChI, SMILES) by CSID. Security token is required.
Search for structure that matches provided MOL within the range specified by options. Returns found CSID list. Security token with Service Subscriber role is required. The search converts the Mol to an InChI and the options parameter allows different layers of the InChI to be searched for against ChemSpider InChIs. For example: eSameSkeleton searches on the connection layer alone (not the h layer - just the connectivity of the rest of the molecule); eAllTautomers searches on everything but the fixed-hydrogen layer; eAllIsomers searches on the molecular formula expression at the beginning of the InChI.
Search for structure that matches provided MOL within the range specified by options and within the specified list of datasources. Returns found CSID list. Security token with Service Subscriber role is required.
