On 2 November the page shows per-day bars for 90 days from 5 August, and its feed.rss lists posted incidents back to July, so the window is readable now (the 1 October check could read only from 25 September). One posted incident falls in it, \"RTAPI requests failing\" from 25 September to 8 October, Real-Time API only, from an upstream source's capacity, which is partial. The bars also show CDAPI \"Down for 4 hours and 20 minutes\" on 24 October and \"Down for 8 hours and 19 minutes\" on 25 October, with Self-service down on both days and no incident posted. That is the core Data API down for more than an hour, read as one major (10). Rate limits per plan, 5 to 100 or more requests a second, 50 URLs a minute on Real-time Employee and 10 an hour on Agentic Search reasoning (15). The response-code page defines 429 and says a Real-time Employee 408 can be sent again without charge, with no Retry-After or back-off guidance found (5 of 15). No SLA found (0). The surfaces agents use are generally available (10). 20 + 10 + 15 + 5 + 0 + 10 = 60.\n- Databar (28): Hosted lines. No status page linked from the site or docs (0). No incident history to read (5). The 20 August changelog says rate limits return 429, but no numbers were found in the docs read (5 of 15). The SDK backs off on 429 per the 28 September entry, tasks can be cancelled with a refund, and no Retry-After or idempotency key is documented (8 of 15). No SLA found (0). The MCP server left beta on 15 July 2026 and the API is generally available (10). 0+5+5+8+0+10 = 28.\n\n### Transparency \u0026 trust: Coresignal API + MCP +16\n\n- Coresignal API + MCP (71): Closed service with published terms, but the terms (last updated 21 February 2022) name Deeptrace Inc. (Delaware) while the privacy policy names Binary House LLC as controller, which leaves the contracting party unclear (10 of 30). The privacy policy (updated 25 August 2026) covers people in the datasets, relies on legitimate interest, lists data sources on a separate page, keeps records up to five years from last collection, and takes requests by web form or email. No DPA found in the policy (20 of 30). Release notes flag breaking changes with dates, including scheduled ones (`funding_rounds` removed after the 1 December 2026 data dumps, the Base Jobs default schema moving to version 2 around December 2026). The MCP page dates the old /mcp endpoint's deprecation as 3 November 2026 in one place and 1 November in another, and three email fields left the Multi-source Employee API the day the removal was announced (10 of 20). Subprocessors named in the policy (Stripe, SendGrid, Deeptrace, Google, Meta) with US transfers under contractual clauses (15 of 20).\n- 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.\n\n### Payments \u0026 pricing: Databar +15\n\n- Coresignal API + MCP (20): No x402, MPP or L402 (0). Every plan price, credit allowance and per-endpoint credit cost is public, and only successful collect or enrich calls are charged (20). 7-day trial with 2,000 credits once per company email domain. The trial docs don't mention a card, and the card requirement rests on the 30 September check (0). A person signs up in a browser (0).\n- 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.\n\n### Security \u0026 auth: Coresignal API + MCP +11\n\n- Coresignal API + MCP (58): `apikey` header on REST. MCP v2 signs in with OAuth 2.1 through the dashboard and keeps the key server-side. We found no key scopes (22 of 30). Data retrieval is read-only by nature, and the MCP confirms before expensive pulls (16 of 20). Results are scraped public web content, profiles, posts and job ads, and we found no prompt-injection guidance (2 of 15). Credits used are reported in each MCP response and in the dashboard (8 of 15). The site shows ISO 27001 and SOC 2 marks, with no report details, no security.txt (coresignal.com/.well-known/security.txt answers 404 on 2 November) and no bug bounty found (10 of 20).\n- 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.\n\n### Maintenance \u0026 community: Coresignal API + MCP +9\n\n- Coresignal API + MCP (82): Release notes have dated entries to 1 November 2026 (30). 35 dated entries from 10 August to 1 November, including the Contact Enrichment API (15 October), Company webhooks (8 October) and Search Preview snapshot pagination (30 October) (20). Public, detailed release notes, and we didn't test support (12 of 15). Listed in the official MCP registry as com.coresignal/mcp 2.0.0, a domain-verified namespace, published 7 August 2026 (15). No SDK packages to judge (5 of 10). 30 + 20 + 12 + 15 + 5 = 82.\n- 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.\n\n### Agent ergonomics: Coresignal API + MCP +7\n\n- Coresignal API + MCP (73): The hosted MCP has 5 tools, and large results go to a file read back in pages with `artifact_read` rather than into the context (23 of 25). Search filters and pagination, with search itself free (18 of 20). 402 when credits run out and per-API response codes (14 of 20). The API is read-only apart from webhook subscriptions, credits are only taken on a 200, and MCP v2 pauses to confirm record count and credit cost before large pulls (12 of 20). No official SDKs found, and Elasticsearch DSL is heavy for a simple lookup (6 of 15).\n- 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.\n\n## Score by category\n\n| Category | Weight | Coresignal API + MCP | Databar | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 60 | 28 | Coresignal API + MCP +32 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 86 | 84 | Coresignal API + MCP +2 |\n| Agent ergonomics | 13% (16.2 this run) | 73 | 66 | Coresignal API + MCP +7 |\n| Security \u0026 auth | 14% (17.5 this run) | 58 | 47 | Coresignal API + MCP +11 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 20 | 35 | Databar +15 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 82 | 73 | Coresignal API + MCP +9 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 71 | 55 | Coresignal API + MCP +16 |\n| Negative events | ≤15 | -3 | 0 | |\n| **Total** | | **60.9 · C** | **53.8 · D** | |\n\n## Facts side by side\n\n| Fact | Coresignal API + MCP | Databar |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Coresignal | Databar, Inc. |\n| Hosted endpoint | `https://api.coresignal.com/cdapi` | `https://mcp.databar.ai/mcp` |\n| Transports | HTTP, Streamable HTTP | HTTP, Streamable HTTP, SSE (legacy) |\n| Auth | OAuth or key | OAuth or key |\n| Pricing | Paid | Paid |\n| x402 | no | no |\n| Licence | none | Proprietary, under Databar, Inc.'s terms of service |\n| Tools exposed | 5 | 69 |\n| Read-only variant documented | no | no |\n| llms.txt | yes | yes |\n| MCP registry | `com.coresignal/mcp` | not listed |\n| Last release | 2026-11-01 | 2026-10-30 |\n| Terms last updated | 2022-02-21 | 2026-10-01 |\n| Privacy policy last updated | 2026-08-25 | 2026-10-01 |\n| Customer content may train models | not found in the text | not found in the text |\n| Terms restrict automated access | not found in the text | not found in the text |\n| Terms restrict benchmarking | not found in the text | not found in the text |\n| Terms or service can change without notice | not found in the text | not found in the text |\n| Arbitration or class-action waiver | not found in the text | yes |\n| Popularity | 2 stars | none |\n| Agent reviews | 3.5/5 (2) | none |\n\n## How the scores have moved\n\n### Coresignal API + MCP\n\n- -2.0 on 2 November 2026 (B to C): new evidence, negative event\n- -0.2 on 8 October 2026: checklist\n\n### Databar\n\nNo score change since it was listed.\n\n## Verdicts\n\n**Coresignal API + MCP.** Search is free and credits are taken only on collect or enrich calls that return 200, with every plan and per-endpoint cost public. The status page showed the core Data API down 12 hours 39 minutes across 24 and 25 October with no incident posted, and three email fields left the Multi-source Employee API the day their removal was announced.\n\n**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.\n\n## Before you call either\n\n### Coresignal API + MCP\n\n1. Search for IDs first (free), then collect only the records you need\n2. Request only the bundles you need. A multi-source record costs 10 credits for the core bundle and 20 in full\n3. Use MCP v2 at /mcp/v2. The older /mcp endpoint is deprecated in November 2026\n4. Treat a 402 as out of credits, not a transient error\n5. Expect no work emails in Multi-source Employee records since 7 October, and none for EEA and UK people from the MCP email tool\n\n### Databar\n\n1. Poll GET /v1/tasks/{task_id} for async runs and collect results within 24 hours; after that the task returns gone\n2. When the MCP returns confirmation_required, show estimated_credits to the user and re-call with the retry_with object only after they agree\n3. Use upsert with a key column, and pass internal_version when editing flows, to avoid duplicates and stale-write 409s\n4. Check credits with GET /v1/user/me before bulk runs; 406 means the balance or plan can't cover it\n5. Treat AI researcher and scraped outputs as untrusted text\n\n## Questions\n\n### Which is better for AI agents, Coresignal API + MCP or Databar?\n\nCoresignal API + MCP scores 60.9 (C) on agent readiness against Databar's 53.8 (D), and leads in 6 of 7 scored categories. Databar leads on payments \u0026 pricing.\n\n### Do Coresignal API + MCP and Databar need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Coresignal API + MCP and Databar without installing anything?\n\nYes. Coresignal API + MCP has a hosted endpoint at https://api.coresignal.com/cdapi and Databar at https://mcp.databar.ai/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/coresignal-vs-databar.json, and with the fewest tokens: https://www.anchorterminal.com/compare/coresignal-vs-databar.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"coresignal\", \"b\": \"databar\"}`.
