Six common jobs, the engine and parameters each one needs, and how many searches a typical setup uses in a month. Pick the closest one and adapt the numbers.

**Quick answer — What is a SERP API used for?**

A SERP API turns a search engine's results page into JSON that software can read. Teams use **SerpCrypto** to give AI agents a web search tool, track rankings, check local results city by city, monitor prices, follow news about a brand and research keywords. Every engine costs one credit per successful search, from $0.30/1K searches as of October 2026, paid in crypto with no KYC.

## Which use case is closest to yours?

- **[AI agents and LLM grounding](https://serpcrypto.com/use-cases/ai-agents/)** — A search tool for agents and RAG apps: fresh, citable results in a compact form.
- **[Rank tracking](https://serpcrypto.com/use-cases/rank-tracking/)** — Positions per keyword, country, city and device, with AI Overview citations.
- **[Local SEO](https://serpcrypto.com/use-cases/local-seo/)** — The map pack and local results as seen from each city you serve.
- **[Price monitoring](https://serpcrypto.com/use-cases/price-monitoring/)** — Google Shopping offers by country: price, merchant and delivery line.
- **[Brand monitoring](https://serpcrypto.com/use-cases/brand-monitoring/)** — New stories and web pages about your names, checked hourly or daily.
- **[Keyword research](https://serpcrypto.com/use-cases/keyword-research/)** — People Also Ask questions, related searches and the features each query triggers.

## Which engine does each use case need, and how many searches?

Typical setups and their monthly searches. A month is 30 daily checks, 4 weekly checks or 720 hourly checks.

| Use case | Engine and key parameters | Example setup | Searches per month |
| --- | --- | --- | --- |
| AI agents | `google` or `bing`; `gl`, `hl`, `period` | 20 agent tasks a day, 50 searches each | 30,000 |
| Rank tracking | `google`; `page`, `location`, `device` | 1,000 keywords, top 10, daily | 30,000 |
| Local SEO | `google` (map pack) or `google_maps`; `location` | 10 queries in 5 cities, weekly | 200 |
| Price monitoring | `google_shopping`; `gl`, `hl` | 500 products in 3 countries, daily | 45,000 |
| Brand monitoring | `google_news` with `period=h`, plus `google` | 20 names, hourly news check | 14,400 |
| Keyword research | `google`; `people_also_ask`, `related_searches` | 200 seed keywords, 2 rounds of expansion | About 2,000 per project |

## How do I estimate the searches my project needs?

Multiply the number of queries by every dimension you repeat them on: pages, locations, devices and checks per month. Each combination is one search and one credit.

`searches = queries × pages × locations × devices × checks`

Then pick the smallest pack that covers one to three months. Credits never expire, so buying ahead does not waste money if your project slows down. A failed search returns an error and is not charged, which keeps the estimate honest even on a bad day.

## Which parameters change the results the most?

Location and language change results more than anything else. A query run with `gl=us` and one run with `gl=gb` can share few results, and local intent queries change again from one city to the next.

- **`gl` and `hl`:** set them for every search; the defaults are the United States and English.
- **`location`:** essential for local SEO and local rank tracking, optional elsewhere.
- **`device`:** mobile pages often order blocks differently; track it when mobile traffic matters.
- **`period`:** keeps only recent pages or stories, which agents and news monitors need.
- **`page`:** each extra page is one more credit, so set the depth you really need.

The [locations and languages](https://serpcrypto.com/docs/locations/) page lists the codes for common markets.

## What do these six workflows share?

They all need the results page as a person in a given place sees it, in a format code can read. That is what a SERP API provides: one request, one results page, as JSON.

They also share the same billing on SerpCrypto. Every engine costs one credit, credits never expire, and you pay in BTC, USDT, USDC, ETH, SOL, LTC with no ID, no selfie and no card. One key and one balance serve every project, and you can create separate keys per project to keep usage apart.

## Which pack covers my use case?

Small projects start with 10,000 searches ($7.50); most of the setups in the table fit in 100,000 searches ($56.25) for one to three months, as of October 2026.

| Plan | Quantity | Price | Price per unit |
| --- | --- | --- | --- |
| Test | 10,000 searches | $7.50 | $0.75/1K searches |
| Build | 100,000 searches | $56.25 | $0.56/1K searches |
| Scale | 500,000 searches | $281.25 | $0.56/1K searches |

In every plan: Every engine at 1 credit per search · Failed requests not charged · Credits never expire · Country, language, city and device targeting

**Before you pay**

- Minimum top-up $25. Top up once in crypto, then buy any plan from your balance.
- Unused balance stays on your account and never expires, and it pays for search credits. When a purchase costs less than the minimum top-up, the part added only to reach the minimum is refundable on request to support within 30 days of the payment, in USDT or USDC, as long as it has not been spent. The rest of the balance is not paid back, except where the law requires it.
- Credited once your payment is checked on the blockchain. Typical network confirmation time: BTC ≈ 20 min · USDT TRC-20 ≈ 1 min · USDT ERC-20 ≈ 5 min · USDC ERC-20 ≈ 5 min · ETH ≈ 5 min · SOL ≈ 1 min · LTC ≈ 15 min

## SERP API use cases: common questions

### Can one account serve several projects?

Yes. API keys you can create and revoke at any time from your dashboard. Give each project its own key, so you can see which one uses your credits and revoke one without touching the others.

### Do different engines cost different amounts?

No. Google Search, Google News, Google Images, Google Maps, Google Shopping and Bing all cost one credit per successful search on SerpCrypto.

### Is there a use case you do not allow?

Yes. Not allowed: Searches meant to find, track or harass a private person, child sexual abuse material, spam, fraud, and any use that breaks the law where you or we operate. The [Acceptable Use Policy](https://serpcrypto.com/acceptable-use/) has the full list.

### Do I need to be a developer?

Some code helps, but the [quick start](https://serpcrypto.com/docs/) gets a first result with a single curl command. No-code tools that can call an HTTP endpoint, such as workflow builders, work too.
