So I made a different list. I signed up for seven free tiers in a single afternoon, ran the same ten queries through each one, and recorded what worked, what failed, and where the limits hit. If you would rather skip APIs entirely, see how far you can [scrape Google without proxies](https://apiserpent.com/blog/scrape-google-without-proxies-free-limits) before a single IP hits the free-ride ceiling. Here is the honest version. No affiliate links. The "best" pick depends entirely on what you are building. **The short answer:** there are seven free Google Search API tiers worth trying in 2026, and their free allowances are Google Custom Search (100 queries/day, but closed to new signups and shutting down 1 January 2027), Serper.dev (2,500 one-time trial queries), Tavily (1,000 credits/month), DataForSEO (~1,500 queries on a $1 trial deposit), SerpApi (250 queries/month), Serpent API (10 free searches), and Brave, whose free tier was withdrawn in late 2025. For an AI agent or RAG pipeline, Serper's 2,500 trial queries go furthest; for checking a JSON shape before you commit, SerpApi's recurring 250/month is the most convenient. All limits below were re-verified on 12 August 2026. ## The Test Same ten queries on every tier: - 5 informational queries (mesothelioma, react vs vue, best protein powder, climate change effects, how to fix leaking tap) - 3 transactional queries (buy iphone 17 case, best ergonomic chair under 300, online MBA programs) - 2 brand queries (apple support, anthropic claude) From the United States, English, desktop. I logged: how many free queries you actually get, what the JSON returns, whether the API includes [AI Overview](https://blog.google/products/search/generative-ai-google-search-may-2024/), response time, and whether a credit card is required to sign up. ## The Results Table Provider Free quota Card required? AI Overview returned? Verdict Google Custom Search (CSE) 100 queries/day No (Google Cloud project) No Sparse data; closed to new signups — EOL Jan 1, 2027 SerpApi.com 250 queries/month No Yes Best for testing the JSON shape Serper.dev 2,500 trial queries No Partial Most usable free tier for AI agents Tavily 1,000 credits/month No n/a (LLM-shaped) Best for RAG, returns content not links DataForSEO $1 trial credit (~1,500 queries) Yes ($1 deposit) Yes Most queries for the money, but the deposit puts off some Brave Search API Free tier removed in late 2025 Yes n/a Skip in 2026 [**Serpent API**](https://apiserpent.com/) 10 free Google searches No Yes (full text + sources) Smallest free quota, richest data shape ## 1\. Google Custom Search Engine (CSE) — Official, but Closed to New Users Google's own free search API. Free up to 100 queries per day per project, then $5 per 1,000 queries. **⚠️ 2026 update:** the Custom Search JSON API is now [closed to new customers](https://developers.google.com/custom-search/v1/overview), and existing customers have until **January 1, 2027** to migrate. If you don't already hold a CSE key, this option is off the table entirely; if you do, treat it as end-of-life and plan your [migration](https://apiserpent.com/blog/google-custom-search-api-shutdown-migration) now. **What you get:** a thin response with title, link, snippet, and minimal SERP feature data. No AI Overview. No People Also Ask. No structured ads. No [featured snippet](https://developers.google.com/search/docs/appearance/featured-snippets) field. **What you do not get:** by default, CSE only searches a list of sites you configure. Toggle "Search the entire web" in the CSE control panel or you will get embarrassingly few results. ``` import requests r = requests.get("https://customsearch.googleapis.com/customsearch/v1", params={ "key": API_KEY, "cx": SEARCH_ENGINE_ID, "q": "best protein powder" }) results = r.json().get("items", []) ``` **Verdict:** good for compliance-strict projects that need the official answer. Bad for anything that needs SERP feature data or rich JSON. ## 2\. SerpApi.com — 250 Free Per Month SerpApi now gives you 250 free Google searches per month on the free plan, no credit card—raised from the 100/month cap we originally tested in May (re-verified July 20, 2026). Unused queries do not roll over. **What you get:** the full SerpApi JSON shape. Organic, ads, AIO, PAA, related searches, knowledge panels. Same response you would get on a paid plan, just rate-limited. **The catch:** the cap is monthly, not per-day. Burn through 100 in an afternoon and you are locked out for the rest of the month unless you upgrade to the $75/month Developer plan. **Verdict:** the best free tier for evaluating the JSON shape before committing. Painful for anything more. ## 3\. Serper.dev — 2,500 Trial Queries Serper has the most generous free trial of the lot — 2,500 queries on signup. It is a one-time credit, not monthly, but 2,500 is enough to ship a real prototype. ``` import requests r = requests.post("https://google.serper.dev/search", headers={"X-API-KEY": API_KEY, "Content-Type": "application/json"}, json={"q": "best protein powder", "gl": "us"}) data = r.json() ``` **What you get:** a clean, AI-agent-friendly Google JSON. Organic, knowledge graph, related searches, PAA. AI Overview is partial — you get the text but not always the full source list. **Catch:** Google only. No Bing, Yahoo, DuckDuckGo. If your prototype only needs Google, this is the friendliest free tier on the list. ## 4\. Tavily — 1,000 Credits/Month for AI Apps Tavily is purpose-built for LLM and RAG pipelines. Free plan is 1,000 credits per month, no card. **What you get:** a relevance-ranked list of _content_ (already extracted from the source pages), not just SERP links. Great for handing straight to an LLM. Not great if you need positions or SERP features — that is not Tavily's job. **Verdict:** if you are building a chatbot or RAG agent, Tavily's free tier is the easiest start. ## 5\. DataForSEO — $1 Trial Credit DataForSEO does not have a "free tier" in the strict sense. They give you $1 in trial credit on signup. With Standard Queue at $0.60 per 1,000, that buys you ~1,500 free queries — the most queries of any free tier in this comparison. **The catch:** the $1 lands after you submit a payment method. Some teams find that off-putting for a sandbox. **What you get:** the full DataForSEO JSON, both Standard Queue and Live mode. Live mode burns the credit faster ($2 per 1,000) but is synchronous. ## 6\. Brave Search API — Skip in 2026 Brave used to have a 1,000-query-per-month free tier. They removed it in late 2025. There is now a 14-day trial that requires a payment method, after which it auto-converts to a paid plan. **Verdict:** if you specifically want Brave's independent index, the trial works. If you are looking for a free tier to play with, look elsewhere. ## 7\. [Serpent API](https://apiserpent.com/) — 10 Free Queries, Richest Data Disclosure: I run Serpent API. I include it because the free quota is small but the data shape is the richest in this comparison — full AI Overview text plus the entire source citation list, plus full SERP feature parsing. Ten queries is enough to hit the playground, run a few real keywords against your code, and decide whether the JSON shape works for what you are building. After that you fund the account or move on. ``` import requests r = requests.get("https://apiserpent.com/api/search", params={ "q": "best protein powder", "engine": "google", "country": "us", "api_key": API_KEY, }) data = r.json() ``` No credit card on signup. The free quota is genuinely free; we do not auto-convert you to anything. ## The Decision Tree - **You are building an LLM/RAG app.** → Tavily (1,000/mo). Or Serper.dev (2,500 trial) if you need SERP shape. - **You are evaluating the JSON shape before committing.** → SerpApi 250/mo or Serpent 10. Both no card. - **You are doing one-off compliance / official-Google work.** → Google CSE. - **You want maximum free queries in a single shot.** → Serper.dev (2,500 trial). - **You want the richest data per call.** → Serpent or SerpApi (both return AIO + full SERP features). ## Why "Free" Always Has a Limit Google does not give SERP data away. Every provider in this comparison either pays a residential proxy network, hits Google directly with rotating infrastructure, or pays Google for indexed access (CSE). All of those have unit costs — cents per query — that the provider has to recoup. Free tiers exist to convert evaluators into paying customers. That is fine; just plan around it. Use the free tier to verify the JSON shape works for your code, then move to a paid plan when you ship. ## What "Cheap Paid" Looks Like After Free For context, here is what each provider charges right above their free tier: Provider First paid tier Cost per 1K queries Google CSE $5 / 1,000 $5.00 SerpApi.com Developer $75/mo $15.00 Serper.dev $50 starter pack $1.00 Tavily Pro $30/mo $0.30 (token-priced) DataForSEO Standard $50 deposit minimum $0.60 **Serpent API Default** $10 deposit minimum **$0.60 (Default), $0.06 (Growth), $0.03 (Scale)** Once you hit the paid tier, the cheapest is Serpent at Scale ($0.03 per 1,000 pages), then Tavily, then Serper. SerpApi is roughly 50× more per query than the cheapest options. ## Recommended Reading Free tiers run out fast.

Enough to confirm the JSON shape works for your project. Pay-as-you-go after that, from $0.03 per 1,000 pages on the Scale tier.

No API gives unlimited free Google search forever. Every provider has either a per-month cap, a one-time credit, or a credit-card requirement. The most useful free tiers are Google CSE (100/day, sparse data), SerpApi (250/mo), Serper.dev (2,500 trial), Tavily (1,000/mo), and Serpent API (10 free, no card). ### What is the catch with Google Custom Search Engine? First: it is closed to new customers, and existing users lose access on January 1, 2027. Beyond that, it searches a limited subset of the web by default, caps at 100 queries/day, and the response is sparse—no AIO, no PAA, no rich SERP features. ### Which free tier gives the most usable data? Serper.dev's 2,500-query trial for sheer volume; Serpent API's 10 free queries for richest data shape; SerpApi 250/month if you want both quality and quantity within a small budget. ### Can I rely on a free tier in production? No. Every free tier is below typical production volume. Use them for evaluation. Paid tiers start at around $0.30 per 1,000 queries on the cheapest providers. ### Do any free tiers require a credit card? DataForSEO requires a $1 minimum deposit. Brave requires a payment method. SerpApi, Serper, and Serpent API let you sign up and use credits with no card. ### Can I combine multiple free tiers to get more queries? Technically yes, but only for evaluation. Most providers' terms forbid running production traffic across multiple free accounts. For real production, pick one paid plan that fits your budget.
