Brand Score Lookup

GET /api/visibility/score

Authentication: Optional (works without an API key). If you do send a key, it must belong to a Starter or Pro account; a free account's key gets a 403 with code: "PLAN_REQUIRED", so leave the key off to use the public lookup.

Look up any brand's public visibility score from the Pendium Brand Index. This is the only endpoint that works without authentication — useful for quick checks and competitive research.

You can search by brand slug, website URL, or name.

Query parameters

Pass exactly one of these:

Parameter	Type	Description
`slug`	string	Brand Index slug (e.g. `acme`). Most reliable — exact match.
`url`	string	Any URL on the brand's website (e.g. `https://www.acme.com/pricing`). Pendium extracts the domain and matches it.
`name`	string	Brand name to search for (e.g. `Acme`). Must match exactly one brand — returns an error if there are multiple matches.

Examples

# By slug (most reliable)
curl "https://pendium.ai/api/visibility/score?slug=stripe"
 
# By URL
curl "https://pendium.ai/api/visibility/score?url=https://stripe.com"
 
# By name
curl "https://pendium.ai/api/visibility/score?name=Stripe"

Response

{
  "brandName": "Stripe",
  "slug": "stripe",
  "overallScore": 78,
  "visibilityLevel": "strong",
  "platformScores": {
    "chatgpt": 85,
    "claude": 72,
    "gemini": 70,
    "aio": 84
  },
  "lastScanDate": "2026-03-16T08:00:00Z",
  "brandPageUrl": "https://pendium.ai/brands/stripe",
  "_pendium": {
    "what_you_are_seeing": "Public visibility score for Stripe..."
  }
}

A platform the scan didn't query (a scoped or single-engine run) comes back with queried: false and a null score, never a real 0 — only read a platform as "scores 0" when queried is true.

Visibility levels

Score range	Level
0–20	`invisible`
21–40	`low`
41–60	`moderate`
61–80	`strong`
81–100	`dominant`

Partial scan failures

Rows marked noResponse: true in queries[].platformRankings represent failed attempts. They remain in the response for diagnostics, but do not count toward brandMentionCount or topic mention rates. Each topic rate counts a question once when at least one platform answered it; a question with no usable answers is excluded. A topic with no answered questions is omitted.

When the brand isn't found

If the brand isn't in the Pendium Brand Index:

{
  "error": "Brand not found",
  "code": "NOT_FOUND"
}

This means the brand hasn't been scanned publicly yet. You can still scan it privately using Trigger a Scan with your API key.
