class mp_api.client.routes.molecules.redox.MoleculesRedoxRester(api_key: str | None = None, endpoint: str = 'https://api.materialsproject.org/', include_user_agent: bool = True, session: requests.Session | None = None, s3_resource: Any | None = None, debug: bool = False, monty_decode: bool = True, use_document_model: bool = True, timeout: int = 20, headers: dict = None, mute_progress_bars: bool = False)[source]¶

Bases: BaseRester[RedoxDoc]

Args: api_key (str): A String API key for accessing the MaterialsProject REST interface. Please obtain your API key at https://www.materialsproject.org/dashboard. If this is None, the code will check if there is a “PMG_MAPI_KEY” setting. If so, it will use that environment variable. This makes easier for heavy users to simply add this environment variable to their setups and MPRester can then be called without any arguments. endpoint (str): Url of endpoint to access the MaterialsProject REST interface. Defaults to the standard Materials Project REST address at “https://api.materialsproject.org”, but can be changed to other urls implementing a similar interface. include_user_agent (bool): If True, will include a user agent with the HTTP request including information on pymatgen and system version making the API request. This helps MP support pymatgen users, and is similar to what most web browsers send with each page request. Set to False to disable the user agent. session: requests Session object with which to connect to the API, for advanced usage only. debug: if True, print the URL for every request monty_decode: Decode the data using monty into python objects use_document_model: If False, skip the creating the document model and return data as a dictionary. This can be simpler to work with but bypasses data validation and will not give auto-complete for available fields. timeout: Time in seconds to wait until a request timeout error is thrown headers (dict): Custom headers for localhost connections.

document_model¶: alias of RedoxDoc

Query molecules redox docs using a variety of search criteria.

Parameters:

molecule_ids (MPculeID, List[MPculeID]) – List of Materials Project Molecule IDs (MPculeIDs) to return data for.
property_ids (str, List[str]) – List of property IDs to return data for.
charge (Tuple[int, int]) – Minimum and maximum charge for the molecule.
spin_multiplicity (Tuple[int, int]) – Minimum and maximum spin for the molecule.
level_of_theory (str) – Desired level of theory (e.g. “wB97X-V/def2-TZVPPD/SMD”)
solvent (str) – Desired solvent (e.g. “SOLVENT=WATER”)
lot_solvent (str) – Desired combination of level of theory and solvent (e.g. “wB97X-V/def2-TZVPPD/SMD(SOLVENT=THF)”)
formula (str, List[str]) – An alphabetical formula or list of formulas (e.g. “C2 Li2 O4”, [“C2 H4”, “C2 H6”]).
elements (List[str]) – A list of elements.
exclude_elements (List(str)) – List of elements to exclude.
chemsys (str, List[str]) – A chemical system, list of chemical systems (e.g., Li-C-O, [C-O-H-N, Li-N]), or single formula (e.g., C2 H4).
electrode (str) – For redox potential queries, a string representation of the reference electrode (currently accepted: “H”, “Li”, “Mg”, “Ca”)
min_reduction_potential (float) – Minimum reduction potential considered
max_reduction_potential (float) – Maximum reduction potential considered
min_oxidation_potential (float) – Minimum oxidation potential considered
max_oxidation_potential (float) – Maximum oxidation potential considered
electron_affinity (Tuple[float, float]) – Minimum and maximum electron affinities

oxidation_energy (Tuple[float, float]) – Minimum and maximum oxidation energies
oxidation_free_energy (Tuple[float, float]) – Minimum and maximum oxidation free energies
num_chunks (int) – Maximum number of chunks of data to yield. None will yield all possible.
chunk_size (int) – Number of data entries per chunk.
all_fields (bool) – Whether to return all fields in the document. Defaults to True.
fields (List[str]) – List of fields in MoleculeDoc to return data for. Default is “molecule_id”, “property_id”, “solvent”, “method”, “last_updated” if all_fields is False.

Returns:

([RedoxDoc]) List of molecule redox documents

count(criteria: dict | None = None) → int | str¶

Return a count of total documents.

Parameters:: criteria (dict | None) – As in .query(). Defaults to None
Returns:: Count of total results, or string indicating error
Return type:: (int | str)

get_data_by_id(document_id: str, fields: list[str] | None = None) → T¶

Query the endpoint for a single document.

Parameters:

document_id – the unique key for this kind of document, typically a task_id
fields – list of fields to return, by default will return all fields

Returns:

A single document.
