Why the edge
Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.
Schema & documentation Databar +84
Clearbit 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.
Databar 84
Each API reference page embeds its OpenAPI 3.1 operation (spec version 0.1.2), with no downloadable file found (20 of 25). llms.txt with 79 API entries and Markdown twins (10). Descriptions say when to use each endpoint, such as headless runs against table runs, and what a delete leaves behind (16 of 20). Typed request bodies with required fields (12 of 15). An error envelope with stable codes and examples for 400, 406 and 422 (14 of 15). v1 paths and a dated changelog, though the API's own versioning isn't described (12 of 15). 20+10+16+12+14+12 = 84.
Maintenance & community Databar +69
Clearbit 4
Read for a closed service. The latest changelog entry is still the Logo API shutdown notice of 24 November 2025, for 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, and a search of the official MCP registry returned none (0). No package to judge (0).
Databar 73
Closed service. Python SDK 2.9.0 on 30 October 2026, 7 days before this check (30). SDK 2.7.0 and 2.8.0 on 6 October and changelog entries on 23, 24, 27, 28, 29 and 30 September and 1 October (20). A public changelog, roadmap and feedback portal, an email address, and a Slack channel on Scale (10 of 15). An official Python SDK and CLI, no other languages (10 of 15). Package health not checked (3 of 10). 30+20+10+10+3 = 73.
Agent ergonomics Databar +66
Clearbit 0
Graded on the interface an outside agent can use. With none open to a new user, every line scores nothing (0).
Databar 66
69 MCP tools with no toolsets found (5), and REST row reads sized by per_page with has_next_page (10 of 25 for the two together). Pagination, row filters and a search parameter on enrichments (16 of 20). Errors name the fix, such as unknown columns with the available ones, 406 for credits, 409 for a stale internal_version and 410 for expired results (18 of 20). Upserts by key, version tokens on flow edits, cancel with refund, and MCP confirmation above 50 credits; MCP tool annotations not confirmed (13 of 20). Python SDK and a CLI, one language (9 of 15). 10+16+18+13+9 = 66.
Security & auth Databar +39
Clearbit 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 (clearbit.com/.well-known/security.txt returns 404), bug bounty or disclosure policy was found (8 of 20).
Databar 47
A workspace API key in a header, never in the URL, and OAuth on the MCP with a Connected apps page to revoke access. No scopes found (20 of 30). No read-only key; MCP balance checks and confirmation above 50 credits, a 30-day trash for workbooks and tables, but row, column and table deletes through the tools (12 of 20). Enrichment results include web-scraped and AI researcher text, with no prompt-injection guidance (3 of 15). Credit usage charts, transaction logs and per-request data logs (12 of 15). No security.txt, disclosure policy, bug bounty or certification found (0 of 20). 20+12+3+12+0 = 47.
Payments & pricing Databar +35
Clearbit 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).
Databar 35
No x402, MPP or L402 (0). Plan prices and credits are public, and each connector's credit cost is shown before a run and in the enrichment's pricing field; credits aren't sold per call outside a plan (15 of 20). A 14-day premium trial with no card, per the pricing FAQ (20). A person signs up in a browser, and API access needs a paid plan (0). 0+15+20+0 = 35.
Transparency & trust Clearbit +18
Clearbit 73
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). The sub-processor page, read in full on 17 October and updated May 2026, names all nine sub-processors (AWS, Google Cloud, FullStory, Hotjar, Mailgun, Mode Analytics, SquadCast, Sentry, Zendesk) with purpose and country, all in the United States, and promises 30 days' notice before a new one starts (20 of 20, up from 8 when the list hadn't been read in full). 15 + 22 + 16 + 20 = 73.
Databar 55
Closed service with terms effective 1 October 2026 naming Databar, Inc. of Delaware (15 of 30). The privacy policy keeps data 'for as long as needed' with no periods; the docs give 24 hours for task results; a DPA is part of the agreement but was not read (15 of 30). The changelog flagged breaking API and SDK changes on 20 August 2026, and the terms let Databar retire any form of programmatic access; no notice period stated (8 of 20). Sub-processors are disclosed under the DPA, which was not read; data is processed in the United States (5 of 20). 15+15+8+5 = 43.

How the scores have moved
Verdicts
Clearbit
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.
Databar
Databar puts 100+ enrichment providers, waterfalls and tables behind one REST API, a Python SDK, a CLI and a hosted MCP server with spending confirmation above 50 credits and stable error codes. API access needs a paid plan or trial, rate limits aren't published as numbers, and no status page or security programme was found.
Before you call either
Clearbit
- 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
- Replace logo.clearbit.com links, which stopped working after 8 December 2025
Databar
- Poll GET /v1/tasks/{task_id} for async runs and collect results within 24 hours; after that the task returns gone
- When the MCP returns confirmation_required, show estimated_credits to the user and re-call with the retry_with object only after they agree
- Use upsert with a key column, and pass internal_version when editing flows, to avoid duplicates and stale-write 409s
- Check credits with GET /v1/user/me before bulk runs; 406 means the balance or plan can't cover it
- Treat AI researcher and scraped outputs as untrusted text
