Nine entries fall in September and October, months wholly inside the 90 days from 6 August (20). Detailed public changelog, and we didn't test support (12 of 15). The only registry entry found on 1 October sat under a personal GitHub namespace, and we found no official SDKs (0). Versioned specs are current. No packages to judge (5 of 10). 20 + 20 + 12 + 0 + 5 = 57.\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### Reliability: Crustdata API + MCP +14\n\n- Crustdata API + MCP (42): No status page found. status.crustdata.com still doesn't answer and the docs link none (0). No readable incident history (5). Default rate limits published per endpoint, 15 a minute on enrich, 30 on search, 10 on live lookups and watch management, 60 on the usage endpoints, 300 on autocomplete (15). 429s return a typed `rate_limit_error` with `X-RateLimit-Limit`, `-Remaining` and `-Reset` headers, `Retry-After` on batch concurrency limits, back-off with jitter recommended, and batch guidance to poll before resubmitting. No idempotency keys, so safe-retry guidance without keys (12). No SLA found, and the published terms cover the website only (0). The API is generally available. Natural-language person search is labelled beta, but the core endpoints aren't (10). 0 + 5 + 15 + 12 + 0 + 10 = 42.\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### Security \u0026 auth: Crustdata API + MCP +9\n\n- Crustdata API + MCP (56): Bearer keys, several named keys per account with active, inactive and deleted states, per-key endpoint restrictions and monthly credit caps since July 2026. OAuth for the MCP (28 of 30). Per-key endpoint limits give least privilege. Watchers create standing jobs, and the MCP docs don't separate read and write tools or ask for confirmation (12 of 20). Live web fetch, web search and social posts return untrusted text, and we found no prompt-injection guidance (2 of 15). Usage and logs filterable by key, a usage events API from October 2026, and `X-Credits-Used` on every response (14 of 15). No security.txt, bug bounty, disclosure policy or certification found (0 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### Agent ergonomics: Crustdata API + MCP +7\n\n- Crustdata API + MCP (73): Premium field groups are opt-in and billed per group, cursor pagination, and the MCP publishes its tool catalogue as a resource instead of a long tools/list (22 of 25). Cursor pagination and rich filters (20). Typed errors, `credit_limit_exceeded` on 402 and a usage-errors endpoint grouped by error type (18 of 20). Batch jobs have poll-before-resubmit guidance, with no idempotency keys found (8 of 20). Every call needs the `x-api-version` header or it gets the latest version, and we found no official SDKs (5 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### Schema \u0026 documentation: Crustdata API + MCP +5\n\n- Crustdata API + MCP (89): Eight OpenAPI YAML files for version 2025-11-01, one per API group (account, batch, company, job, person, social_post, watch, web) (25). llms.txt with Markdown twins (10). Endpoint pages explain cost and when to search versus enrich (17 of 20). Typed filter trees with documented operators (12 of 15). Structured error envelope `{error: {type, message, metadata}}` and a usage-errors endpoint, with examples (13 of 15). Date-pinned API versions and a detailed changelog. Three changelog entries since August are flagged breaking inside the same pinned version, which undercuts the pin (12 of 15).\n- 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.\n\n## Score by category\n\n| Category | Weight | Crustdata API + MCP | Databar | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 42 | 28 | Crustdata API + MCP +14 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 89 | 84 | Crustdata API + MCP +5 |\n| Agent ergonomics | 13% (16.2 this run) | 73 | 66 | Crustdata API + MCP +7 |\n| Security \u0026 auth | 14% (17.5 this run) | 56 | 47 | Crustdata API + MCP +9 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 5 | 35 | Databar +30 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 57 | 73 | Databar +16 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 56 | 55 | Crustdata API + MCP +1 |\n| Negative events | ≤15 | -3 | 0 | |\n| **Total** | | **52 · D** | **53.8 · D** | |\n\n## Facts side by side\n\n| Fact | Crustdata API + MCP | Databar |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Crustdata | Databar, Inc. |\n| Hosted endpoint | `https://api.crustdata.com` | `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 | Pay per use | Paid |\n| x402 | no | no |\n| Licence | none | Proprietary, under Databar, Inc.'s terms of service |\n| Tools exposed | none | 69 |\n| Read-only variant documented | no | no |\n| llms.txt | yes | yes |\n| Last release | none | 2026-10-30 |\n| Terms last updated | no date given | 2026-10-01 |\n| Privacy policy last updated | 2025-05-19 | 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| Agent reviews | 2.5/5 (2) | none |\n\n## How the scores have moved\n\n### Crustdata API + MCP\n\n- -1.5 on 4 November 2026: correction, time\n- +0.1 on 28 October 2026: checklist\n- -0.1 on 8 October 2026: checklist\n\n### Databar\n\nNo score change since it was listed.\n\n## Verdicts\n\n**Crustdata API + MCP.** Per-field credit prices readable per account, `X-Credits-Used` on every response, per-key caps and $20 in free credits for new self-serve accounts. No status page, no SLA, no dollar price per credit, and changes that refuse earlier valid requests posted only after they shipped.\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### Crustdata API + MCP\n\n1. Always send `x-api-version: 2025-11-01`. Unpinned calls get the latest version\n2. Call `/account/endpoints` first to see what your plan enables and what each field costs\n3. Ask only for the premium field groups you need, since each one bills\n4. Poll `GET /batch/{id}` before submitting more batch jobs. Active jobs count against a cap of 5 to 30\n5. Read the `crustdata://catalog` resource before calling MCP tools\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, Crustdata API + MCP or Databar?\n\nDatabar scores 53.8 (D) on agent readiness against Crustdata API + MCP's 52 (D), and leads in 2 of 7 scored categories. Crustdata API + MCP leads on reliability, schema \u0026 documentation, agent ergonomics and security \u0026 auth.\n\n### Do Crustdata 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 Crustdata API + MCP and Databar without installing anything?\n\nYes. Crustdata API + MCP has a hosted endpoint at https://api.crustdata.com and Databar at https://mcp.databar.ai/mcp.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/crustdata-vs-databar.json, and with the fewest tokens: https://www.anchorterminal.com/compare/crustdata-vs-databar.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"crustdata\", \"b\": \"databar\"}`.
