# Clearbit > Clearbit is a B2B data provider for company, contact and IP intelligence, acquired by HubSpot. It still runs enrichment, reveal and prospecting APIs for existing customers, and HubSpot's Breeze Intelligence carries its data for new buyers. - Canonical: https://www.anchorterminal.com/tools/clearbit - Markdown: https://www.anchorterminal.com/tools/clearbit.md (~4,950 tokens) - Slim: https://www.anchorterminal.com/tools/clearbit.min.md (~1,030 tokens, same facts, less prose, for token-sensitive contexts) - JSON: https://www.anchorterminal.com/tools/clearbit.json (this page as data, same URL with Accept: application/json) - Site index for agents: https://www.anchorterminal.com/llms.txt (full text: https://www.anchorterminal.com/llms-full.txt) - API: https://www.anchorterminal.com/api/v1/index.json - Updated: 2026-10-14 ## Overview **Grade F · 13.5/100 · rank #1056 of 1076 · #19 in Lead & company data · not agent-ready · not for agents · confidence medium** ## Assessment There is no public API or MCP server an outside agent can call today. Clearbit's APIs still run for existing customers behind a login, and its free tools and Logo API were retired in 2025. HubSpot's Breeze Intelligence is the route for new buyers, through HubSpot rather than Clearbit. ## Facts | Field | Value | | --- | --- | | Vendor | HubSpot, Inc.

Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 30 | 6.0 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 0 | 0.0 | | Agent ergonomics | 13% | 16.2 | 0 | 0.0 | | Security & auth | 14% | 17.5 | 8 | 1.4 | | Payments & pricing | 10% | 12.5 | 0 | 0.0 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 4 | 0.3 | | Transparency & trust (editorial 61, provenance 71) | 7% | 8.8 | 66 | 5.8 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **13.5 → F** | ### Why each score - Reliability 30: Read with the hosted lines. An Atlassian Statuspage with 22 components and incident history (20). Since 16 July 2026 it shows a minor Salesforce synchronisation incident from 18 September to 23 September and authentication errors on 31 August marked no impact, so minor only. These affect existing customers, since no outside agent can reach the APIs (10 of 30, reduced from 20 because the history covers a service closed to new users). No published limits for an outside agent (0). No overload or retry guidance on a public page (0). No SLA found (0). The standalone service is closed to new sign-ups, so the general-availability line scores nothing (0). - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 0: Graded on the interface an outside agent can use. The API docs sit behind the customer login and there is no sign-up, so the contract, description, typed-input, example and versioning lines score nothing. clearbit.com/llms.txt returns 404 (0). This says nothing about the service for existing customers. - Agent ergonomics 0: Graded on the interface an outside agent can use. With none open to a new user, every line scores nothing (0). - Security & auth 8: Graded on the interface an outside agent can use, so the credential, least-privilege, injection and audit lines score nothing (0). The trust page says Clearbit is SOC 2 Type 2 compliant and runs annual penetration tests. No security.txt, bug bounty or disclosure policy was found (8 of 20). - Payments & pricing 0: No x402, MPP or L402 (0). No public prices, and /pricing redirects to the home page (0). The free tools ended on 30 April 2025 (0). No sign-up route at all (0). - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 4: Read for a closed service. The latest changelog entry is the Logo API shutdown after 8 December 2025, more than 180 days ago (0). No dated entries in the last 90 days (0). A dated changelog and a support page, with the help centre behind a bot check (4 of 15). No current SDK or MCP server (0). No package to judge (0). - Transparency & trust 66: Closed service under terms dated 30 May 2025 that name HubSpot, Inc. (15). The privacy policy, updated 31 August 2026, lists public, customer and third-party sources, and the trust page commits to deleting a terminated customer's account associations within 90 days (22 of 30). Dated sunset notices with months of warning, such as the Logo API announced in February 2025 for December (16 of 20). A sub-processor page listing locations, which we didn't read in full (8 of 20). Fix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (14 items): https://www.anchorterminal.com/fixes/clearbit.md (JSON https://www.anchorterminal.com/fixes/clearbit.json) ### What we couldn't check - unchecked: the help centre article on buying Clearbit, behind a bot check, which a search result quoted as saying new standalone subscriptions are no longer offered - Whether existing customers' API keys and endpoints have an end date - unchecked: the full sub-processor list and the Breeze Intelligence API surface inside HubSpot ### Sources - home page: (seen 2026-10-14) - release notes: (seen 2026-10-14) - terms of service: (seen 2026-10-14) - privacy policy: (seen 2026-10-14) - trust page: (seen 2026-10-14) - status components and incidents: (seen 2026-10-14) - docs redirect to login: (seen 2026-10-14) - help centre (bot check, not read): (seen 2026-10-14) ## Who's behind it (provenance 71/100, checked 2026-10-14) | Check | Finding | Points | | --- | --- | --- | | Legal entity named | HubSpot, Inc. | 20/20 | | Domain age | clearbit.com, no registry record we could read | 0/15 | | Endpoint on the vendor's domain | clearbit.com | 15/15 | | Terms of service | read, states 6 of the 7 things a reader expects, and has 1 clause that costs points | 7.1/10 | | Privacy policy | read, states 7 of the 8 things a reader expects | 9.3/10 | | Status page | status.clearbit.com | 10/10 | | Changelog | published | 10/10 | | security.txt | not found | 0/10 | The terms were last updated on 30 May 2025 and the privacy policy on 31 August 2026. Both name HubSpot, Inc. under its Clearbit brand. clearbit.com/.well-known/security.txt answers with an HTML page, not a security.txt file. help.clearbit.com answered with a Cloudflare bot check, so its article on buying Clearbit wasn't read. A search result quoted it as saying new standalone subscriptions are no longer offered, which we couldn't confirm first-hand. status.clearbit.com is an Atlassian Statuspage (clearbit.statuspage.io). No RDAP lookup was made for clearbit.com. ### Terms and privacy, as read A reading by a fixed set of rules, each answered with the vendor's own sentence.

Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score. ## Strengths - Public status page with 22 components and incident history - Dated sunset notices with months of warning, such as the Logo API - Privacy policy updated 31 August 2026 and a sub-processor page with locations ## Weaknesses - No public API or MCP server an outside agent can call - No sign-up or public prices, and the home page links only to a customer login - Free tools retired on 30 April 2025 and the Logo API after 8 December 2025 - No security.txt, and the help centre sits behind a bot check ## Before you call it (notes for agents) 1. Don't plan to call Clearbit. Hand the task to a person with an existing Clearbit account, or use HubSpot's Breeze Intelligence through HubSpot 2. Replace logo.clearbit.com links, which stopped working after 8 December 2025 ## Similar tools Ranked by shared capabilities, then score.

The badge or a plain link to this page verifies the listing, from a page on clearbit.com or one of its subdomains. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "clearbit", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp.
