What is exa-contents?

A tool guide for extracting readable text, highlights, summaries, links, images, and subpages from web addresses that you already have, using Exa.

Use it to fetch and prepare website or document content from known URLs for research, analysis, or later writing.

It provides clean information for an AI agent without requiring the agent to search for those pages first, and can limit results by freshness.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00108	$0.02639
Opus 5	$0.00054	$0.01319
Sonnet 5	$0.00022	$0.00528
Haiku 4.5	$0.00011	$0.00264

Security

Grade A, and why

exa-contents scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.

On Activation

Read brand/competitors.md / brand/landscape.md if present for URL shortlists. Optional.
Confirm Exa auth (MCP or EXA_API_KEY) via mktg doctor if unsure.
Prefer MCP web_fetch_exa when available; otherwise use the cURL examples below.
If the page is auth-walled (X/Twitter login stub), route to mktg-x instead.

Exa Contents

Requires API key: Get one at https://dashboard.exa.ai/api-keys

Header: x-api-key: $EXA_API_KEY

Use POST https://api.exa.ai/contents when the agent already knows the URLs and needs clean, LLM-ready extraction without running a new search. Start with one content mode: highlights for compact agent context, text for broad page context, or summary for Exa-side compression.

Quick Start (cURL)

Basic text extraction

curl -sS -X POST "https://api.exa.ai/contents" \
  -H "Content-Type: application/json" \
  -H "x-api-key: $EXA_API_KEY" \
  -d '{
    "urls": ["https://example.com"],
    "text": true
  }'

Highlights with freshness control

curl -sS -X POST "https://api.exa.ai/contents" \
  -H "Content-Type: application/json" \
  -H "x-api-key: $EXA_API_KEY" \
  -d '{
    "urls": ["https://arxiv.org/abs/2307.06435"],
    "highlights": {
      "query": "methodology and results"
    },
    "maxAgeHours": 24,
    "livecrawlTimeout": 12000
  }'

Endpoint

POST https://api.exa.ai/contents

Authentication: x-api-key: <API_KEY> header. Exa also accepts Authorization: Bearer <API_KEY>, but prefer x-api-key in cURL examples for consistency.

Use this endpoint for known-URL extraction. If the agent needs discovery or ranking first, use POST /search.

Parameters

Core request parameters

Parameter	Type	Required	Default	Description
`urls`	string[]	Yes	-	URLs to extract content from. Use this for known URLs.
`text`	boolean or object	No	-	Return full page text as markdown. Object form supports `maxCharacters`, `includeHtmlTags`, `verbosity`, `includeSections`, and `excludeSections`.
`highlights`	boolean or object	No	-	Return key excerpts. Prefer `true` for agent workflows unless a custom focus is needed.
`summary`	boolean or object	No	-	Return per-page LLM summaries. Use when the caller wants Exa-side compression or structured extraction.
`maxAgeHours`	integer	No	-	Freshness control. `0` always live crawls; `-1` uses cache only; omit for default cache-first behavior with crawl fallback.
`livecrawlTimeout`	integer	No	`10000`	Timeout for live crawling in milliseconds. Use `10000` to `15000` for most freshness-sensitive calls.
`subpages`	integer	No	`0`	Number of linked subpages to crawl from each URL.
`subpageTarget`	string or string[]	No	-	Terms used to prioritize which subpages matter, such as `["api", "reference", "pricing"]`.
`extras.links`	integer	No	`0`	Number of links to extract from each page.
`extras.imageLinks`	integer	No	`0`	Number of image URLs to extract from each page.
`compliance`	string	No	-	Enterprise-only compliance mode, such as `hipaa`, when enabled for the account.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
