Use Zhihu topic search to map an unfamiliar subject

Locate the question within a wider subject

When exploring home energy storage, you may encounter batteries, solar power, and backup supplies together. Search topics with keyword to find entry points for further reading. This is not a professional terminology standard, and similarly named topics may have different scopes. Write down what you need to understand before deciding which candidates are useful.

Do not merge neighbouring concepts too early

Use offset and limit to inspect ranges and examine the context of each candidate. If hypothetical results include energy storage and portable power banks, their shared use of batteries does not make them identical subjects. Record possible relationships as questions to verify through reliable references and concrete discussions. The operation does not build an independently validated concept tree.

Plan the next reading step

Your concept worksheet could include the source, question it may help answer, related but distinct concepts, and material to read next. The number of results is not a measure of knowledge coverage, and a missing term does not prove a concept does not exist. The useful outcome is a limited, revisable reading index. Before publishing technical explanations, substantiate conclusions with reliable evidence rather than relying solely on the name of a platform topic.

Request URL and parameters

Run the Python example

Install requests and set TRMESH_API_TOKEN in your environment. Replace the sample identifiers with the public object you intend to inspect. Example IDs may no longer be available.

import os
import requests

# Read your own developer key from the server environment.
url = "https://api.trmesh.com/openapi/api/v1/zhihu/web/fetch_topic_search_v3"
params = {
    "keyword": "YOUR_KEYWORD"
}
response = requests.get(
    url, params=params, timeout=30,
    headers={"Authorization": f"Bearer {os.environ['TRMESH_API_TOKEN']}"},
)
response.raise_for_status()
payload = response.json()
print(payload)  # Inspect the actual response before mapping fields
