Gemini + live news
Native function declarations plus an OpenAI-compatible endpoint. Very large context, which pairs well with reading article bodies in bulk.
| Vendor | Google, United States |
|---|---|
| Base URL | https://generativelanguage.googleapis.com/v1beta |
| Model id | gemini-2.5-flash |
| Model credential | GEMINI_API_KEY |
| Tool format | Gemini-native function declarations. An OpenAI-compatible endpoint also exists if you prefer the common shape. |
| News API key | none required |
| Vendor docs | https://ai.google.dev/gemini-api/docs/function-calling |
Base URLs and model ids change often, and several vendors run separate mainland and international endpoints with non-interchangeable keys. Check the vendor docs above before copying. The part that does not change is the tool itself — our API has no key, no version negotiation and no SDK.
Working example
import requests
from google import genai
from google.genai import types
client = genai.Client() # GEMINI_API_KEY
search_news = types.FunctionDeclaration(
name="search_news",
description=("Search worldwide news published in the last 30 days. "
"Free, keyless. Use 2-5 keywords, not a question."),
parameters={
"type": "OBJECT",
"properties": {
"q": {"type": "STRING"},
"date": {"type": "STRING", "enum": ["today", "yesterday", "24h", "7d", "30d"]},
"lang": {"type": "STRING"},
"size": {"type": "INTEGER"},
},
"required": ["q"],
},
)
IDENT = {"agent_name": "news-agent", "software": "gemini",
"model": "gemini-2.5-flash"}
cfg = types.GenerateContentConfig(tools=[types.Tool(function_declarations=[search_news])])
chat = client.chats.create(model="gemini-2.5-flash", config=cfg)
r = chat.send_message("What happened with grain exports this week?")
for part in r.candidates[0].content.parts:
if part.function_call:
data = requests.get("https://freenewsapi.ai/v1/search",
params={**dict(part.function_call.args), **IDENT},
timeout=20).json()
r = chat.send_message(types.Part.from_function_response(
name="search_news", response={"result": data}))
print(r.text)Worth knowing about Gemini
- Native format nests declarations under
tools[].function_declarationsand returns afunctionCallpart. - An OpenAI-compatible base exists at
generativelanguage.googleapis.com/v1beta/openai/if you would rather reuse the OpenAI snippet. - Has its own Google Search grounding. Turn it off when you want news from this corpus specifically, or you will not know which source answered.
Test the tool without the model
Before debugging a tool-calling loop, confirm the data side works. It needs no credentials, so this runs anywhere:
curl "https://freenewsapi.ai/v1/search?q=grain+exports&date=7d&size=5"If that returns results and your loop still fails, the problem is in the model's tool handling, not in the data.
Prompt it properly
The single most common failure is the model phrasing the query as a sentence. Search is
AND across every term, so q=what happened with grain exports matches nothing.
Put this in the system prompt:
Use search_news for anything about current events or recent developments.
Phrase the query as 2-5 keywords that would appear in a headline, never as a question.
Good: "grain export prices". Bad: "what is happening with grain exports".
Scan titles first. Only request full_text for articles you will actually cite.
If a search returns nothing, drop the least essential keyword and try once more.
No results means no coverage in this corpus \u2014 not that the event did not happen.More in system prompts.
Same format
Gemini uses the gemini tool-calling shape. These take the same code with a different base URL and model name: none in this list.
