CyberDict API

CyberDict exposes a small public JSON API so the dataset can be queried from a script, a terminal or an AI agent. Free tier: no API key, no account, no signup. Base URL: https://cyberdict.yanivhaliwa.com

Endpoints

Method	Path	Returns
GET	`/api/terms`	The terms, with optional filters
GET	`/api/stats`	Totals and counts by category

GET `/api/terms`

Returns matching terms ordered by name. All parameters are optional and combine with AND.

Parameter	Meaning
`q`	Free-text search across term, short_description and full_description.
`category`	Exact category match, e.g. Attack, Concept, Protocol, Tool, Methodology.
`skill_level`	Exact skill level match.
`limit`	Maximum number of records to return (1-1000).
`offset`	Skip this many matches; use with `limit` to paginate. `total` in the response is the full match count.
`id`	Return the single record with this numeric id (404 if none).

curl -s "https://cyberdict.yanivhaliwa.com/api/terms?q=nmap"

{"terms":[{"id":362,"term":"1337 (Leet)","short_description":"Alternative alphabet ...", ...}],"total":359}

GET `/api/stats`

Totals and per-category counts. Useful for checking the dataset size before pulling it.

curl -s https://cyberdict.yanivhaliwa.com/api/stats

Rate limits

Free tier: 50 calls per calendar month per IP, at most 10 records per call. Call 51 returns HTTP 429 (free_quota_exceeded) with a Retry-After header until the 1st of next month. Every response carries X-Free-Quota-Remaining.

Need more? Paid plans with up to 1000 records per call and a fixed monthly quota are available on RapidAPI and Zyla API Hub.

Plans

Same endpoints and parameters on every plan. Marketplace plans return up to 1000 records per call with no per-IP limit; you call through the marketplace with its API key.

Where	Plan	Price / month	Calls / month
This site (no key)	Free	$0	50 per IP, max 10 records per call
RapidAPI	BASIC	$0	50
	PRO	$4.99	10,000
	ULTRA	$14.99	100,000
Zyla API Hub	BASIC	$24.99	10,000
	PRO	$49.99	100,000
	PROPLUS	$99.99	100,000

Zyla also offers a 7-day trial (50 calls) and annual billing (2 months free).

Errors

Errors are always JSON, never an HTML page:

{"error":"Too many requests. Please try again later."}

Unknown paths under /api/ return HTTP 404 with a JSON body listing the available endpoints.

Notes for agents

Query with ?q= rather than fetching the whole collection and filtering client-side — it is far smaller and stays within the rate limit.
The full unfiltered response is large (hundreds of KB). Prefer a filter.
Cross-origin browser requests are restricted to this site's own origin. Server-side and command-line requests, which send no Origin header, are allowed.
