SerpApi's free tier gives you 250 searches per month, which runs out fast. And while plenty of APIs advertise "free tiers," many require a credit card on file before you can use them — which means a forgotten card on file could start charging you months later.
This guide covers every search API that offers a genuinely free tier with no credit card required. Each one tested and verified as of April 2026.
Key Takeaways
- 7 APIs offer free search access without a credit card — SearchHive, Serper.dev, Brave Search API, Tavily, Google CSE, Bing API, and DuckDuckGo
- Brave Search API gives $5 free every month — that's 1,000 searches, auto-replenished
- SearchHive SwiftSearch gives 500 free credits with full access to all API endpoints
- Serper.dev gives 2,500 free queries on signup — the most generous one-time free tier
- Google Custom Search offers 100 free queries/day (3,000/month) — the highest sustained free volume
- DuckDuckGo via community libraries is completely free and unlimited but unofficial and fragile
Why "No Credit Card" Matters
It's not just about avoiding charges. APIs that require a credit card upfront often:
- Auto-charge when you exceed free limits instead of blocking requests
- Charge for overage at rates you didn't agree to when you signed up
- Make it intentionally difficult to cancel — you have to find the billing page, navigate past retention offers, and confirm
- Store your card on file indefinitely, creating a security surface
The APIs listed here either don't require a card at all, or let you use their free tier without one. If you exceed the limit, they block requests — they don't charge you.
1. SearchHive SwiftSearch
Free tier: 500 credits on signup. No credit card. Full access to SwiftSearch, ScrapeForge, and DeepDive APIs.
SearchHive is built specifically for developers building AI and data tools. The free tier isn't a trial — it's a permanent free plan with 500 credits. You get access to search, scraping, and deep analysis endpoints.
import requests
# Get started in under a minute — just sign up, grab your key, go
response = requests.get(
"https://api.searchhive.dev/v1/search",
headers={"Authorization": "Bearer YOUR_FREE_API_KEY"},
params={"q": "best python frameworks 2026", "limit": 10}
)
for result in response.json()["results"]:
print(f"{result['title']} → {result['url']}")
What you get for free:
- 500 API credits (across all three APIs)
- Google search results
- Web scraping with anti-bot features
- Deep analysis endpoint
- Dashboard access
- No rate limit throttling on free tier
No CC required: Confirmed. Sign up with email, get API key, start immediately.

2. Serper.dev
Free tier: 2,500 free queries on signup. No credit card required.
Serper is one of the fastest Google Search APIs available, returning results in 1-2 seconds. The free tier is generous but it's one-time — once your 2,500 queries are used, you need to buy credits.
import requests
response = requests.post(
"https://google.serper.dev/search",
headers={"X-API-KEY": "YOUR_FREE_KEY"},
json={"q": "best python frameworks 2026"}
)
for result in response.json().get("organic", []):
print(f"{result['title']} → {result['link']}")
What you get for free:
- 2,500 Google search queries (one-time)
- Real-time results in 1-2 seconds
- Knowledge graph, organic results, people also ask
- All search types (images, news, maps, etc.)
No CC required: Confirmed. Sign up with Google or email.
Caveat: This is a one-time grant, not a monthly replenishment. Good for evaluation and small projects, not sustained free usage.
3. Brave Search API
Free tier: $5 in free credits every month (1,000 searches). No credit card required.
Brave runs its own independent search index — 30B+ pages — and offers API access. The free tier auto-replenishes monthly, making this the best option for sustained free usage.
import requests
response = requests.get(
"https://api.search.brave.com/res/v1/web/search",
headers={"X-Subscription-Token": "YOUR_KEY"},
params={"q": "best python frameworks 2026", "count": 10}
)
for result in response.json().get("web", {}).get("results", []):
print(f"{result['title']} → {result['url']}")
What you get for free:
- 1,000 searches per month (auto-replenished)
- Full Brave search results (not Google — their own index)
- Web, images, news, video endpoints
- Up to 50 queries/second
No CC required: Confirmed. Sign up with email.
Caveat: Brave uses its own search index, not Google. Results quality is good but different from what you'd get from a Google SERP API.
4. Tavily Search
Free tier: 1,000 API credits per month. No credit card required.
Tavily is designed for AI agents and LLM applications. The free tier gives you optimized search results with content chunks ready for model consumption.
from tavily import TavilyClient
client = TavilyClient(api_key="YOUR_FREE_KEY")
results = client.search(
query="best python frameworks 2026",
max_results=5
)
for r in results["results"]:
print(f"{r['title']} → {r['url']}")
print(f" {r['content'][:120]}...\n")
What you get for free:
- 1,000 API credits per month (auto-replenished)
- Search results optimized for LLM consumption
- Answer extraction
- LangChain and LlamaIndex integration
No CC required: Confirmed.
5. Google Custom Search JSON API
Free tier: 100 queries per day (3,000 per month). No credit card required for the free tier.
This is Google's official programmatic search API. It requires setting up a Custom Search Engine in Google Cloud Console, which takes about 10 minutes.
import requests
response = requests.get(
"https://www.googleapis.com/customsearch/v1",
params={
"key": "YOUR_API_KEY",
"cx": "YOUR_SEARCH_ENGINE_ID",
"q": "best python frameworks 2026"
}
)
for item in response.json().get("items", []):
print(f"{item['title']} → {item['link']}")
What you get for free:
- 100 queries per day, 3,000 per month
- Official Google search results
- Good documentation
No CC required: Confirmed for the free tier. Billing is required only if you enable paid usage.
Caveat: Setup is more involved — you need a Google Cloud project, API credentials, and a Custom Search Engine configuration. Also limited to 10 queries/second.
6. Bing Web Search API (Azure Free Tier)
Free tier: 1,000 transactions per month. Azure free account required (no CC).
Microsoft's Bing search API through Azure Cognitive Services gives you 1,000 free searches per month.
import requests
response = requests.get(
"https://api.bing.microsoft.com/v7.0/search",
headers={"Ocp-Apim-Subscription-Key": "YOUR_KEY"},
params={"q": "best python frameworks 2026"}
)
for result in response.json().get("webPages", {}).get("value", []):
print(f"{result['name']} → {result['url']}")
What you get for free:
- 1,000 searches per month
- Bing search results
- Azure SDK integration
No CC required: Azure free account signup requires phone verification but no credit card for the free tier.
Caveat: Azure setup is heavier than other options. The free tier is generous but you need to navigate Azure's console.
7. DuckDuckGo (Unofficial Libraries)
Free tier: Completely free, unlimited. No API key, no account, no credit card.
Multiple Python libraries interface with DuckDuckGo's HTML search results. Completely unofficial, but functional for many use cases.
from duckduckgo_search import DDGS
with DDGS() as ddgs:
for result in ddgs.text("best python frameworks 2026", max_results=10):
print(f"{result['title']} → {result['href']}")
print(f" {result['body'][:120]}...\n")
What you get for free:
- Unlimited searches
- No account needed
- Decent result quality
No CC required: N/A — no account at all.
Caveat: Unofficial. DuckDuckGo can block automated requests. Libraries can break when DuckDuckGo changes their HTML. Not suitable for production.
Best Practices for Free Tiers
Stagger your usage. If you have 3,000 monthly queries on Google CSE, that's 100/day. Set up rate limiting to spread requests across the day rather than burning through them in a burst.
Combine multiple free tiers. Running Google CSE (100/day) + Brave ($5/mo = ~167/day) + SearchHive (500 total) + Bing (33/day) gives you roughly 10,000+ searches per month for free. Build a wrapper that distributes queries across providers.
import random
import requests
def search_any(query: str) -> list:
"""Search across multiple free APIs, falling back on failure."""
providers = [search_brave, search_searchhive, search_google_cse]
random.shuffle(providers)
for provider in providers:
try:
results = provider(query)
if results:
return results
except Exception:
continue
return []
Cache everything. If you're building a tool that searches for the same terms repeatedly (like a price tracker), cache results with a TTL. A 1-hour cache can reduce your API usage by 90%.
