Company Logo API: Get a Company Logo

Your team needs to show a company’s logo everywhere a domain appears: enriching new signups, rendering CRM/company profiles, or auditing which brands appear in internal dashboards. By the end of this guide, you’ll programmatically fetch a clean, hosted logo URL for any domain, wire it into your pipeline, and understand how to cache and fall back when a logo is missing—using a single API call.

Why Klazify is the best API for getting logos you can trust

Logos only add value if they’re correct, safe to display, and fast to retrieve at scale. Klazify pairs a dedicated logo endpoint with domain intelligence so you can standardize logos across your stack and make policy decisions about where they render.

Accurate website categorization using AI: Klazify analyzes full site content, which helps detect official domains before you display a logo. This is especially useful when multiple lookalike domains exist and you only want logos for verified company sites.
Global coverage: Handle signups and traffic from many countries and languages. If the site is new to your system, Klazify can classify it and deliver a logo URL in the same workflow.
Real-time classification: Use fresh, up-to-date categorizations (e.g., news, ecommerce, finance) alongside the logo to decide whether to show or hide branding in sensitive contexts.
Industry-level categories (IAB taxonomy): Get standardized categories you can map to your brand-safety rules, making it straightforward to suppress logos on prohibited categories.
Simple API integration: A single POST request returns a hosted logo URL. You can call it directly from signup flows, ETL jobs, or microservices.
Compliance and filtering: Combine the logo URL with content categories to whitelist/blacklist which company images appear in your UI based on internal or regulatory policies.

In short, you’ll fetch a logo URL and also have the option to layer it with categorization and company context to control how and where logos are displayed across your app.

What you’ll implement

The working path below is designed for production pipelines:

Resolve a logo URL from a domain using a single API call.
Store and cache the returned URL per domain (e.g., keyed by the eTLD+1).
Use categorization data to implement rules for when to display or suppress logos.
Batch domains, retry transient failures, and avoid re-calling for known domains unless you need a refresh.

You’ll also see how to handle unknown or newly registered domains and how to map Klazify’s IAB categories to your own taxonomy for consistent policy enforcement.

Endpoint for fetching a hosted company logo

Use the dedicated endpoint to obtain a hosted logo URL from a domain. The result is a URL you can embed directly in your product or store in your database. Failed or unreachable calls are not billed. The Starter plan is $39.99/mo with a 7-day trial.

Endpoint: POST https://www.klazify.com/api/domain_logo

cURL request

curl -X POST "https://www.klazify.com/api/domain_logo" \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"url":"https://cbsnews.com"}'

Replace YOUR_API_KEY with your token. The JSON body accepts the domain or URL you want to resolve to a logo.

Python example

import os
import json
import requests

API_KEY = os.getenv("KLAZIFY_API_KEY", "YOUR_API_KEY")
ENDPOINT = "https://www.klazify.com/api/domain_logo"

def get_logo_url(domain_or_url):
headers = {
"Authorization": f"Bearer {API_KEY}",
"Content-Type": "application/json"
}
payload = {"url": domain_or_url}
r = requests.post(ENDPOINT, headers=headers, json=payload, timeout=15)
r.raise_for_status()
data = r.json()

# The response contains a hosted logo URL in the JSON.
# Extract the logo URL from the response object.
# We read both common patterns to be robust:
logo_url = None
if isinstance(data, dict):
# If nested under 'domain' as in categorization responses
domain_block = data.get("domain")
if isinstance(domain_block, dict):
logo_url = domain_block.get("logo_url")

# Or directly present at the top-level
if not logo_url:
logo_url = data.get("logo_url")

return logo_url, data

if __name__ == "__main__":
logo_url, raw = get_logo_url("https://example.com")
print("Logo URL:", logo_url)
print("Raw response:", json.dumps(raw, indent=2))

Store the logo URL in your database keyed by the normalized domain (e.g., example.com). Use it directly in your UI or emails. If the field is missing or empty, treat it as a cache miss and trigger a fallback (more on fallbacks below).

Using categorization and company data alongside the logo

In many pipelines, the next step after getting a logo is deciding where to display it. You may, for example, block logos on prohibited content categories or enrich a CRM record with tags and technologies. For that, use the main categorization endpoint.

Endpoint URL: https://www.klazify.com/api/categorize

Below is the official example response. Use it as a reference for fields available when you need to enrich policy decisions or user experiences around the logo. Do not modify field names or values.

Key fields you’ll actually use:

domain.logo_url: A hosted logo URL suitable for embedding or caching.
domain.categories: Names and confidences, plus IAB mapping when present, which you can map to your own taxonomy for brand safety or visibility rules.
objects.company: Company identity and business context (name, location, employeesRange, revenue, tags, tech) to enrich CRM or analytics.
domain_registration_data: Useful for heuristics like treating very new domains differently before showing logos.
similar_domains: Helpful for deduplication and discovering related properties your product may also need to display or suppress.

When to call the logo endpoint vs using categorization’s logo field

Both approaches can provide a logo URL. The logo-specific endpoint offers a direct path when you only need the logo. If you also need categories, company data, or registration info, you can call the main categorization endpoint and read domain.logo_url.

Approach	Primary Use	Returned Context	Logo Field	When to Choose
POST /api/domain_logo	Just get the hosted logo URL	Logo URL in JSON	Hosted URL present in response	Signup enrichment, UI rendering, or ETL that only needs a logo
POST /api/categorize	Get categories, company data, and a logo together	Categories, company, registration, similar domains	domain.logo_url	Brand safety checks, CRM enrichment, or analytics plus logo
Manual scraping (non-API)	Attempt to parse favicons or images from HTML	Unstructured; site-dependent	N/A	Use only as a last resort; fragile and time-consuming to maintain

How to plug the logo into your pipeline

Data model

Key on the normalized domain (eTLD+1), e.g., example.com.
Store: logo_url (string), source (domain_logo or categorize), updated_at (timestamp), and a status (ok, missing, blocked).
Optionally store category mappings and IAB codes if you plan to filter visibility.

Caching and refresh

Cache hits: Do not re-fetch logos for known domains on every render. Serve from your DB or CDN.
Refresh schedule: Consider a periodic refresh job for popular domains (e.g., weekly or monthly) to catch rebrands.
404 handling: If a previously valid URL 404s, fall back to a fresh API call, then update your cache.

Display rules driven by categories

Map domain.categories to your internal taxonomy. If a category is disallowed, mark the logo as blocked and do not render it.
Leverage the confidence values to gate risky categories or require manual review when confidence is below your threshold.
Because categorization uses IAB mapping, you can align it with ad tech or brand safety policies across your org.

Handling unknown or new domains

If the logo endpoint returns no usable URL, treat it as missing and display a placeholder initial or generic badge.
For new domains with sparse content, first call categorize to get more context and decide whether logos should render at all.
Re-queue unknown domains for a second attempt after a short delay; some sites become classifiable after content or DNS propagation stabilizes.

Operational details: batching, throughput, and resilience

Integrations often need to handle thousands of domains per hour or more. Here’s a pragmatic approach:

Batching: Group domains into background jobs. Even though the endpoint accepts one domain per call, batching at the job level lets you parallelize requests across workers.
Rate limits: Design with backoff and retry. Implement exponential backoff on 429/503 and jitter to avoid thundering herds. Consult the Documentation for the latest guidance.
Retries: Retry only idempotent failures (network timeouts, 5xx). Do not retry 4xx validation errors—fix the input instead.
Idempotency: Your worker should de-duplicate in-flight jobs per domain to avoid redundant calls.
Monitoring: Track success ratio, timeouts, HTTP status codes, and average latency per endpoint.
Cost control: Cache aggressively. Failed or unreachable calls are not billed; still, avoid unnecessary retries to save time and quota.

Mapping Klazify categories to your taxonomy

Klazify provides a hierarchical system with IAB taxonomy mapping. Many teams maintain their own policy categories (e.g., “Prohibited,” “Sensitive,” “Allowed”). Create a mapping table from Klazify category names and IAB codes to your internal enums.

Start with domain.categories[].name and, when available, the IAB code (e.g., IAB-632-596) to anchor your mapping.
Where multiple categories are present, apply your strictest rule (e.g., if any category is prohibited, suppress the logo).
Keep your mapping versioned so policy changes can be audited.

Storing and serving the logo

Direct embed: Use the hosted logo URL in your product pages and emails.
CDN proxy: Optionally proxy through your CDN for caching and consistent performance. Respect the original cache headers when available.
Placeholders: If no logo URL is provided or an image fails to load, show an initial-based avatar generated from the company name or domain.
Security: Serve over HTTPS only. Validate the URL format before storing if you sanitize inputs elsewhere.

End-to-end example: enriching a signup

On form submit, normalize and validate the domain from the email or website field.
Check your cache. If missing, call POST /api/domain_logo and store the returned URL.
Optionally call /api/categorize to populate domain.categories and objects.company for CRM enrichment.
Apply policy rules: if categories match suppressed groups, mark the logo as blocked for display contexts that enforce brand safety.
Render the logo in your admin UI immediately; downstream services consume from your DB or a message queue.

Governance: auditing where logos appear

Logos are a visual endorsement. Teams often need to enforce where they appear:

Brand safety: Hide logos next to prohibited content categories based on your mapping table.
Vertical-specific: For finance or healthcare contexts, show logos only for domains that meet stricter category or registration-age criteria.
Audit: Record when a logo was fetched, which categories were present, and who approved overrides.

FAQ

Can I get both the logo and categories in one call?
Yes—use the main categorization endpoint to read domain.logo_url along with categories and company data. If you only need the logo, call the logo endpoint directly.
How should I cache results?
Cache by normalized domain (eTLD+1). Store the logo URL and a last-updated timestamp. Periodically refresh popular domains and on 404s re-fetch from the API.
What if the domain is new or the logo isn’t available?
Treat it as missing and use a placeholder. Optionally call the categorization endpoint to gather more context and re-queue the domain for a later retry.
How do I handle batching and rate limits?
Run parallel workers with deduplication per domain, implement exponential backoff with jitter on 429/503, and persist a queue for retries. Consult the Documentation for current guidance.
Can I map categories to my internal policy taxonomy?
Yes. Use domain.categories and, where present, IAB mappings to drive your own Allowed/Sensitive/Prohibited logic. Apply the strictest rule when multiple categories exist.
