# Perplexity Search API vs Parallel in 2026: one key answers both

Compared on Nov 12, 2026. The page: https://specstream.ai/compare/perplexity-vs-parallel

Perplexity's Search API costs $5 per 1,000 requests, or $1 with Fast Search, for up to 20 results. Parallel costs $1 per 1,000 on `turbo` and `fast`, and $5 on `basic` and `advanced`, the mode a call gets when it names none.

SpecStream answers both calls with one key, each in its own JSON, at $1 per 1,000 searches of up to 10 results. Its Search API scores 97.9 F-score on all 1,000 SimpleQA Verified questions.

## SpecStream, the Perplexity Search API and Parallel side by side

| | SpecStream | Perplexity Search API | Parallel Search API |
|---|---|---|---|
| The call your code sends | Both, on one key: `POST https://api.specstream.ai/perplexity/search` with the key as a Bearer token, and `POST https://api.specstream.ai/parallel/v1/search` with the key in `x-api-key` | `POST https://api.perplexity.ai/search` with `query`, one string or an array of up to 5 queries | `POST https://api.parallel.ai/v1/search` with `search_queries`, which is required, and a `mode` |
| Price per 1,000 searches | $1 for up to 10 results on both paths, page text included. $5 on the Parallel path for `advanced`, the mode a call gets when it names none | $5.00 per 1,000 successful requests, $1.00 with Fast Search (`search_type: "fast"`). A request of up to 5 queries is billed once | $1 on `turbo` and `fast`, $5 on `basic` and `advanced`. A call that names no mode runs `advanced` |
| Results in one call | Up to 20 on the Perplexity path (50 with `search_type: "people"`) and up to 100 on the Parallel path. Each started block of 10 more adds $0.0012, so 20 results cost $0.0022 | `max_results` 1 to 20 for web search, up to 50 for people search, 10 by default. The price is the same for 1 or 20 | 10 included per request. Public modes cap results at 20, and each result beyond the first 10 adds $1 per 1,000 |
| Page text | Read on every search, at no extra cost. `max_tokens_per_page` and `max_tokens` set the snippet length on the Perplexity path, `excerpt_settings.max_chars_per_result` on the Parallel path | Page text extracted into each result's `snippet`. `max_tokens` and `max_tokens_per_page` do not change the price | Excerpts from each page. Excerpt length does not change the price |
| Empty and failed calls | A call that returns no results costs nothing. A busy call answers `429` with `Retry-After` in that API's own error body and is not charged | Invalid, rate limited and failed requests are not billed. A successful response is billed even when it returns no results | `429` when rate limited or over quota |
| Speed and limits | The fast search on both paths, on the same key, limits and history as the rest of your account | 50 query units per second on every tier. Each query in a multi-query request uses one unit | `turbo` in about 200ms, `fast` about 700ms, `advanced` about 3s. 600 searches a minute |
| Published accuracy | 97.9 F-score on all 1,000 SimpleQA Verified questions (978 correct), 64.0 item F1 on all 200 WideSearch tasks | 95% on SimpleQA Verified and 53.5 on WideSearch in Parallel's September 2026 run, on 100-question samples | 97% on SimpleQA Verified and 57.6 on WideSearch for `advanced` in its own run, on the same samples |
| Free to start | $10 of credit, no card, which covers 10,000 searches. Credit you buy never expires | API credits bought in the console, with auto top-up when the balance runs low | $5 free monthly with a card on file, plus up to $80 at signup |
| Beyond search | Extract API at $0.80 per 1,000 pages, and Deep Search: every match on the live web as structured rows at 5¢, 15¢ or $1 a row, priced before it runs | Agent API tools, on top of the model's tokens: `web_search` at $2.50 per 1,000 invocations, `fetch_url` at $0.0005 an invocation | Extract at $1 per 1,000 URLs, Task at $5 to $2,400 per 1,000 runs, Responses at $10 to $250 per 1,000 requests |

## Why teams choosing between Perplexity and Parallel use SpecStream

### Run the same question through both formats

Each API keeps its own request and its own JSON on SpecStream. This script sends one question in Perplexity's format and in Parallel's, with one key, and prints the result count, the seconds each call took and the first link.

```
import os
import time
import requests

KEY = os.environ["SPECSTREAM_API_KEY"]
BASE = "https://api.specstream.ai"
Q = "who maintains the requests library for Python"

calls = {
    "Perplexity": lambda: requests.post(f"{BASE}/perplexity/search", headers={"Authorization": f"Bearer {KEY}"},
                                        json={"query": Q, "max_results": 10}, timeout=30).json()["results"],
    "Parallel": lambda: requests.post(f"{BASE}/parallel/v1/search", headers={"x-api-key": KEY},
                                      json={"search_queries": [Q], "mode": "fast"}, timeout=30).json()["results"],
}

for name, call in calls.items():
    start = time.perf_counter()
    results = call()
    seconds = time.perf_counter() - start
    print(f"{name}: {len(results)} results in {seconds:.2f} s, first: {results[0]['url']}")
```

The two calls cost $0.002 together, from the $10 of credit a new account gets. Change `Q` to a question from your own logs and run it again.

### What 10,000 searches a month cost on each

Take an agent that makes 10,000 searches a month of 10 results each, at list prices.

SpecStream: $10 on either path. $50 if every Parallel call runs `advanced`.

Perplexity: $50 on standard web search, $10 with Fast Search.

Parallel: $10 on `turbo` or `fast`, $50 on `basic` or `advanced`.

At 20 results a call, Parallel adds $1 per 1,000 results beyond the first 10, so `fast` costs $110. SpecStream costs $22. Perplexity keeps one price per request whatever the count: $50, or $10 with Fast Search.

### The most accurate web search API in the world

The SpecStream Search API scores a 97.9 F-score on all 1,000 official SimpleQA Verified questions, with 978 correct. On WideSearch it scores 64.0 item F1 and 43.4 row F1 on all 200 official tasks, and the Extract API scores 0.908 F1 on WCXB. The scores, the method and the other APIs' published scores are at [specstream.ai/benchmarks](https://specstream.ai/benchmarks?utm_source=alternatives&utm_campaign=perplexity-vs-parallel).

The Perplexity and Parallel figures in the table come from Parallel's own run of September 2026, a GPT-5.6 Sol agent on 100-question samples. Ours are on every official question.

### What each path reads and returns

Perplexity: `POST /perplexity/search` reads `query`, `max_results` up to 20 (50 for people), `search_type`, `search_domain_filter` with a `-` before a domain to leave it out, `search_recency_filter`, `search_after_date_filter` and `search_before_date_filter`, `max_tokens` and `max_tokens_per_page`. It returns `results[]` with `title`, `url`, `snippet`, `date` and `last_updated`. Send one query a call: a `query` array of two or more is refused with a `422`, so a fan out of 5 queries is 5 calls, $0.005 together. `country`, `search_language_filter` and `search_context_size` are accepted and do not change the search.

Parallel: `POST /parallel/v1/search` reads `search_queries` (two or more are searched together), `mode`, `advanced_settings.max_results` up to 100, `source_policy` and `excerpt_settings`, and returns `results[]` with `url`, `title`, `publish_date` and `excerpts`. The search runs on `search_queries`; `objective` and `fetch_policy` are accepted and do not change it.

The official SDKs need only the address. Every parameter and reply field, with what we measured, is in the [Perplexity](https://specstream.ai/migrate/perplexity?utm_source=alternatives&utm_campaign=perplexity-vs-parallel) and [Parallel](https://specstream.ai/migrate/parallel?utm_source=alternatives&utm_campaign=perplexity-vs-parallel) migration guides.

```
import os
from perplexity import Perplexity
from parallel import Parallel

key = os.environ["SPECSTREAM_API_KEY"]
perplexity = Perplexity(api_key=key, base_url="https://api.specstream.ai/perplexity")
parallel = Parallel(api_key=key, base_url="https://api.specstream.ai/parallel")
```

### Zero retention on any key

Set `zero_retention` when you create a key, or later. A search made with that key keeps no request text and no answer after the reply. The charge keeps the account, the key, the request ID, the price and the time. Set `eu_egress_only` and the key's searches leave only from our server in Madrid.

### Search, pages and rows on the same key

The same key reads up to 20 pages a call with the [Extract API](https://specstream.ai/extract-api?utm_source=alternatives&utm_campaign=perplexity-vs-parallel) at $0.80 per 1,000 pages, a page with no text not charged, and runs [Deep Search](https://specstream.ai/deep-search?utm_source=alternatives&utm_campaign=perplexity-vs-parallel), which returns every match on the live web as structured rows at 5¢, 15¢ or $1 a row. The most a Deep Search run can cost is approved before it starts.

## Other search APIs teams compare with Perplexity and Parallel

### Exa

Search by type: $4 per 1,000 requests on `lite` and $7 on `auto` and `fast`. SpecStream answers Exa's `POST /search` at `https://api.specstream.ai/exa`, at $0.001 a search of up to 10 results.

### Tavily

Search sold by credit: an advanced search is 2 credits, at $0.008 a credit pay as you go. SpecStream answers Tavily's `POST /search` at `https://api.specstream.ai/tavily`, in Tavily's JSON, at $0.001 a search.

### Brave Search API

Web search at $5 per 1,000 requests. SpecStream answers Brave's `GET /res/v1/web/search` at `https://api.specstream.ai`, at $0.001 a search.

### Serper

Google results as prepaid credits, from $1.00 per 1,000 on the 50k pack. SpecStream answers Serper's `POST /search` at `https://api.specstream.ai/serper`, and SpecStream credit never expires.

## How to move your Perplexity or Parallel calls to SpecStream

1. Create a key under Agents & API in the workspace. A new account gets $10 of credit, no card, which covers 10,000 searches.

2. Change the host where your code calls each API, and send the SpecStream key where that API takes its key:

Perplexity: `https://api.specstream.ai/perplexity` in place of `https://api.perplexity.ai`, the key as a Bearer token.

Parallel: `https://api.specstream.ai/parallel` in place of `https://api.parallel.ai`, the key in `x-api-key`.

3. Leave the parser as it is. A search of up to 10 results costs $0.001, and $0.005 on the Parallel path in `advanced`. On a `429`, wait the seconds in `Retry-After` and send the call again. Nothing was charged.

## Frequently asked questions

### Is the Perplexity Search API better than Parallel?

In Parallel's own September 2026 run, Perplexity scored 95% on SimpleQA Verified against 97% for Parallel `advanced`, and the two tied at 74% on BrowseComp. SpecStream answers both calls on one key at $1 per 1,000 searches and scores 97.9 F-score on all 1,000 SimpleQA Verified questions.

### Perplexity Search API vs Parallel pricing: what does each cost?

Both list $1 and $5 per 1,000: Perplexity $5 for standard search and $1 with Fast Search, Parallel $1 on `turbo` and `fast` and $5 on `basic` and `advanced`, its default. SpecStream is $1 per 1,000 on either path, and $5 for Parallel's `advanced`.

### Can I keep my Perplexity or Parallel code?

Yes, with 1 line changed per API: the base address. The `perplexityai` and `parallel-web` SDKs take it as `base_url`, the request body stays the same, and the reply comes back in the same JSON.

### How many results does one call return?

Up to 20 on Perplexity's web search and up to 20 on Parallel's public modes. SpecStream returns up to 100 on the Parallel path and 20 on the Perplexity path, at $0.0012 for each started block of 10 above 10.

### Is the Perplexity Search API the same as Sonar?

No: Sonar was a model that wrote an answer, and Sonar Chat Completions support ended on September 27, 2026. The Search API returns ranked results with no model, at $5 per 1,000 requests. The [Sonar alternatives](https://specstream.ai/alternatives/perplexity-sonar?utm_source=alternatives&utm_campaign=perplexity-vs-parallel) page covers the answer side.

### Which one is free to start?

SpecStream gives $10 of credit with no card, which covers 10,000 searches. Parallel gives $5 a month with a card on file, plus up to $80 at signup. Perplexity sells API credits in its console.
