# Parallel Web Systems API
## Overview
This skill provides access to **Parallel Web Systems** APIs for web search, deep research, and content extraction. It is the **primary tool for all web-related operations** in the scientific writer workflow.
**Primary interface:** Parallel Chat API (OpenAI-compatible) for search and research.
**Secondary interface:** Extract API for URL verification and special cases only.
**API Documentation:** https://docs.parallel.ai
**API Key:** https://platform.parallel.ai
**Environment Variable:** `PARALLEL_API_KEY`
## When to Use This Skill
Use this skill for **ALL** of the following:
- **Web Search**: Any query that requires searching the internet for information
- **Deep Research**: Comprehensive research reports on any topic
- **Market Research**: Industry analysis, competitive intelligence, market data
- **Current Events**: News, recent developments, announcements
- **Technical Information**: Documentation, specifications, product details
- **Statistical Data**: Market sizes, growth rates, industry figures
- **General Information**: Company profiles, facts, comparisons
**Use Extract API only for:**
- Citation verification (confirming a specific URL's content)
- Special cases where you need raw content from a known URL
**Do NOT use this skill for:**
- Academic-specific paper searches (use `research-lookup` which routes to Perplexity for purely academic queries)
- Google Scholar / PubMed database searches (use `citation-management` skill)
---
## Two Capabilities
### 1. Web Search (`search` command)
Search the web via the Parallel Chat API (`base` model) and get a **synthesized summary** with cited sources.
**Best for:** General web searches, current events, fact-finding, technical lookups, news, market data.
```bash
# Basic search
python scripts/parallel_web.py search "latest advances in quantum computing 2025"
# Use core model for more complex queries
python scripts/parallel_web.py search "compare EV battery chemistries NMC vs LFP" --model core
# Save results to file
python scripts/parallel_web.py search "renewable energy policy updates" -o results.txt
# JSON output for programmatic use
python scripts/parallel_web.py search "AI regulation landscape" --json -o results.json
```
**Key Parameters:**
- `objective`: Natural language description of what you want to find
- `--model`: Chat model to use (`base` default, or `core` for deeper research)
- `-o`: Output file path
- `--json`: Output as JSON
**Response includes:** Synthesized summary organized by themes, with inline citations and a sources list.
### 2. Deep Research (`research` command)
Run comprehensive multi-source research via the Parallel Chat API (`core` model) that produces detailed intelligence reports with citations.
**Best for:** Market research, comprehensive analysis, competitive intelligence, technology surveys, industry reports, any research question requiring synthesis of multiple sources.
```bash
# Default deep research (core model)
python scripts/parallel_web.py research "comprehensive analysis of the global EV battery market"
# Save research report to file
python scripts/parallel_web.py research "AI adoption in healthcare 2025" -o report.md
# Use base model for faster, lighter research
python scripts/parallel_web.py research "latest funding rounds in AI startups" --model base
# JSON output
python scripts/parallel_web.py research "renewable energy storage market in Europe" --json -o data.json
```
**Key Parameters:**
- `query`: Research question or topic
- `--model`: Chat model to use (`core` default for deep research, or `base` for faster results)
- `-o`: Output file path
- `--json`: Output as JSON
### 3. URL Extraction (`extract` command) — Verification Only
Extract content from specific URLs. **Use only for citation verification and special cases.**
For general research, use `search` or `research` instead.
```bash
# Verify a citation's content
python scripts/parallel_web.py extract "https://example.com/article" --objective "key findings"
# Get full page content for verification
python scripts/parallel_web.py extract "https://docs.example.com/api" --full-content
# Save extraction to file
python scripts/parallel_web.py extract "https://paper-url.com" --objective "methodology" -o extracted.md
```

## Model Selection Guide
The Chat API supports two research models. Use `base` for most searches and `core` for deep research.
| Model | Latency | Strengths | Use When |
|--------|------------|----------------------------------|-----------------------------|
| `base` | 15s-100s | Standard research, factual queries | Web searches, quick lookups |
| `core` | 60s-5min | Complex research, multi-source synthesis | Deep research, comprehensive reports |
**Recommendations:**
- `search` command defaults to `base` — fast, good for most queries
- `research` command defaults to `core` — thorough, good for comprehensive reports
- Override with `--model` when you need different depth/speed tradeoffs

## Python API Usage
### Search
```python
from parallel_web import ParallelSearch
searcher = ParallelSearch()
result = searcher.search(
objective="Find latest information about transformer architectures in NLP",
model="base",
)
if result["success"]:
print(result["response"]) # Synthesized summary
for src in result["sources"]:
print(f" {src['title']}: {src['url']}")
```
### Deep Research
```python
from parallel_web import ParallelDeepResearch
researcher = ParallelDeepResearch()
result = researcher.research(
query="Comprehensive analysis of AI regulation in the EU and US",
model="core",
)
if result["success"]:
print(result["response"]) # Full research report
print(f"Citations: {result['citation_count']}")
```
### Extract (Verification Only)
```python
from parallel_web import ParallelExtract
extractor = ParallelExtract()
result = extractor.extract(
urls=["https://docs.example.com/api-reference"],
objective="API authentication methods and rate limits",
)
if result["success"]:
for r in result["results"]:
print(r["excerpts"])
```

## MANDATORY: Save All Results to Sources Folder
**Every web search and deep research result MUST be saved to the project's `sources/` folder.**
This ensures all research is preserved for reproducibility, auditability, and context window recovery.
### Saving Rules
| Operation | `-o` Flag Target | Filename Pattern |
|-----------|-----------------|------------------|
| Web Search | `sources/search_<topic>.md` | `search_YYYYMMDD_HHMMSS_<brief_topic>.md` |
| Deep Research | `sources/research_<topic>.md` | `research_YYYYMMDD_HHMMSS_<brief_topic>.md` |
| URL Extract | `sources/extract_<source>.md` | `extract_YYYYMMDD_HHMMSS_<brief_source>.md` |
### How to Save (Always Use `-o` Flag)
**CRITICAL: Every call to `parallel_web.py` MUST include the `-o` flag pointing to the `sources/` folder.**
```bash
# Web search — ALWAYS save to sources/
python scripts/parallel_web.py search "latest advances in quantum computing 2025" \
-o sources/search_20250217_143000_quantum_computing.md
# Deep research — ALWAYS save to sources/
python scripts/parallel_web.py research "comprehensive analysis of the global EV battery market" \
-o sources/research_20250217_144000_ev_battery_market.md
# URL extraction (verification only) — save to sources/
python scripts/parallel_web.py extract "https://example.com/article" --objective "key findings" \
-o sources/extract_20250217_143500_example_article.md
```
### Why Save Everything
- **Reproducibility / audit / peer review**: every claim traces back to its raw source material.
- **Context recovery**: if context is compacted mid-task, re-read saved results from `sources/`.
- **Cost efficiency**: check `sources/` first to avoid redundant (paid) API calls and reuse results across sections.
### Logging
When saving research results, always log:
```
[HH:MM:SS] SAVED: Search results to sources/search_20250217_143000_quantum_computing.md
[HH:MM:SS] SAVED: Deep research report to sources/research_20250217_144000_ev_battery_market.md
```
### Before Making a New Query, Check Sources First
Before calling `parallel_web.py`, check if a relevant result already exists in `sources/`:
```bash
ls sources/ # Check existing saved results
```

## Routing
| Task | Tool |
|------|------|
| Web search, current events, market/technical lookup | `parallel_web.py search` (this skill) |
| Comprehensive research report | `parallel_web.py research --model core` (this skill) |
| Citation verification / DOI metadata from a known URL | `parallel_web.py extract` (this skill) |
| Scholarly paper retrieval (peer-reviewed journals to cite) | `research-lookup` (routes to Perplexity) |
| Google Scholar / PubMed / CrossRef database search | `citation-management` |
When writing scientific documents: gather background with `search`/`research` before drafting a section, verify any specific URL with `extract`, and route purely academic paper searches to `research-lookup`. Always check `sources/` first and save every result back (see above).

## Environment Setup
```bash
# Required: Set your Parallel API key
export PARALLEL_API_KEY="your_api_key_here"
# Required Python packages (uv is the toolchain on this machine)
uv pip install openai # For Chat API (search/research)
uv pip install parallel-web # For Extract API (verification only)
# Or run the script ad hoc without a venv:
# uv run --with openai --with parallel-web scripts/parallel_web.py search "query"
```
The `parallel-web` PyPI package installs as the `parallel` import module (used only by `extract`).
Get your API key at https://platform.parallel.ai

## Error Handling
The script handles errors gracefully and returns structured error responses:
```json
{
"success": false,
"error": "Error description",
"timestamp": "2025-02-14 12:00:00"
}
```
**Common issues:**
- `PARALLEL_API_KEY not set`: Set the environment variable
- `openai not installed`: Run `uv pip install openai`
- `parallel-web not installed`: Run `uv pip install parallel-web` (only needed for extract)
- `Rate limit exceeded`: Wait and retry (default: 300 req/min for Chat API)
