# PubChmAPI Library

## Overview

### Introduction

The **PubChmAPI** Python package simplifies interaction with the PubChem database via the PUG-REST API. Unlike traditional wrappers with hard-coded functions, PubChmAPI uses dynamic metaprogramming to generate endpoints, ensuring full coverage of the PubChem schema. It handles URL generation, automatic batching, and throttling to provide a seamless data retrieval experience.

---

## Naming Convention

Functions in **PubChmAPI** follow a strict semantic naming convention to eliminate ambiguity:

`domain_identifier_get_operation_option`

* **Domain:** The primary database being queried (e.g., `compound`, `substance`, `assay`, `gene`).
* **Identifier:** The input type provided (e.g., `cid`, `name`, `smiles`, `geneid`).
* **Operation:** The specific data to retrieve (e.g., `properties`, `aids`, `synonyms`).
* **Option (Optional):** Filters or variants (e.g., `active`, `inactive`, `2d`).

---

## Functions

### Compound Property Functions (By Name)

Retrieve calculated properties using a compound name (e.g., "Aspirin").
**Format:** `compound_name_get_[Property](identifier)`

#### Code Example

```python
# test_pubchmapi.py
from PubChmAPI import (
    compound_name_get_Title,
    compound_name_get_MolecularFormula,
    compound_name_get_MolecularWeight,
    compound_name_get_CanonicalSMILES,
    compound_name_get_InChI,
    compound_name_get_InChIKey,
    compound_name_get_IUPACName,
    compound_name_get_XLogP,
    compound_name_get_ExactMass
)

def test_pubchmapi():
    compound = "Aspirin"
    print("Testing PubChmAPI functions for:", compound)

    print("Title:", compound_name_get_Title(compound))
    print("Molecular Formula:", compound_name_get_MolecularFormula(compound))
    print("Molecular Weight:", compound_name_get_MolecularWeight(compound))
    print("Canonical SMILES:", compound_name_get_CanonicalSMILES(compound))
    print("InChI:", compound_name_get_InChI(compound))
    print("InChIKey:", compound_name_get_InChIKey(compound))
    print("IUPAC Name:", compound_name_get_IUPACName(compound))
    print("XLogP:", compound_name_get_XLogP(compound))
    print("Exact Mass:", compound_name_get_ExactMass(compound))

if __name__ == "__main__":
    test_pubchmapi()
```

#### Sample Output

```text

### Compound CID Functions

Retrieve data using a Compound Identifier (CID).
**Format:** `compound_cid_get_[Operation](identifier)`

#### Code Example

```python
# test_pubchmapi_cid.py

    compound_cid_get_description,
    compound_cid_get_synonyms,
    compound_cid_get_sids,

    compound_cid_get_aids,
    compound_cid_get_aids_active,
    compound_cid_get_aids_inactive,
    compound_cid_get_assaysummary
)

def test_cid_functions():
    cid = 2244  # Aspirin CID
    print(f"Testing PubChmAPI CID functions for CID: {cid}")

    print("Description:", compound_cid_get_description(cid))
    print("Synonyms:", compound_cid_get_synonyms(cid)[:5], "...")
