Errors 400, 401, 404, 422, 429, 501 and 503 in the spec, a troubleshooting page, examples pages for REST and MCP and a Postman collection (14 of 15). The path carries v1, but no changelog was found (5 of 15). 25+7+11+10+14+5 = 72.\n- registercheck.de API (83): The docs name a public OpenAPI 3.1 document at api.registercheck.de/v1/openapi.json, which on 21 October covered 53 operations but was thin (11 schemas, no security scheme, FastAPI's default 422 where the API answers 400). The richer OpenAPI 3.2 document behind the reference (61 operations, 213 schemas, 68 enums) was embedded in the pages and not served as a file. Both per the 21 October check, not re-read (20 of 25). llms.txt, llms-full.txt and per-page Markdown (10). Reference descriptions say when to use an endpoint, what it costs and where coverage ends. Two pages still disagree, as the authentication guide gives 400 for a missing key where the errors guide gives 401 for no valid key, and the quickstart prices contact endpoints that the roadmap lists as not served (16 of 20). Typed parameters with lengths, ranges and enums such as `register_type`, and since 26 October the company filter refuses input its schema refuses (13 of 15). Examples in seven languages and example responses on reference pages, and a full error code table, less the inconsistencies above (12 of 15). A dated changelog and a migration guide with `Deprecation` and `Sunset` headers, but `/v1` changes in place with no new version (12 of 15). 20 + 10 + 16 + 13 + 12 + 12 = 83.\n\n### Security \u0026 auth: CompanyLens +7\n\n- CompanyLens (47): REST keys rotate and revoke at once from the dashboard, with a separate sandbox prefix, but carry the whole account with no per-endpoint restrictions. The MCP server uses OAuth through Clerk with dynamic client registration and only openid, profile and email scopes, or long-lived service tokens on Agent plans. No key in the URL (20 of 30). The data surface is read-only; no write actions on registry data (15 of 20). Company names, addresses and officer details are filed by third parties, with no prompt-injection guidance (5 of 15). get_usage and the usage endpoint show plan use; the privacy policy says audit logs are kept at least a year, with no per-call log documented for customers (7 of 15). security.txt answered 403 and no disclosure policy, bug bounty or certification was found (0 of 20). 20+15+5+7+0 = 47.\n- registercheck.de API (40): Bearer keys only, never in the URL, revocable on the next request. Keys are not scoped and carry the account's full permissions, including deleting lists and monitors. The MCP server uses OAuth 2.1 with five scopes such as `companies:read` and `monitors:write` (20 of 30). No read-only key. The MCP docs page (docs.registercheck.de/docs/mcp) says `delete_monitor` stops a monitor after the assistant asks the user to confirm, and that is the source credited; the tool annotations themselves were not readable without signing in (8 of 20). Company names, purposes and person names are filed by the public and returned verbatim, with no guidance on treating them as untrusted (5 of 15). A usage breakdown by endpoint and key exists, but the docs say it is unreliable and may show empty. `Request-Id` on error responses, and `Registercheck-Credits-Charged` on every response to a call made with a key, whatever its status (7 of 15). Security programme 0 of 20, mostly because we couldn't read the vendor's site. www.registercheck.de, where a security page, disclosure policy or certification would normally be published, answered robots.txt with a bot check on 21 October and 4 November, so whether a programme exists there is unchecked, not found missing. What we could check was empty, with no security.txt on the docs host (404 on 4 November) or on the api and mcp hosts (21 October) and no disclosure route, bug bounty or certification in the docs. Webhooks are signed with HMAC-SHA256 under Standard Webhooks. 20 + 8 + 5 + 7 + 0 = 40.\n\n## Score by category\n\n| Category | Weight | CompanyLens | registercheck.de API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 39 | 40 | registercheck.de API +1 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 72 | 83 | registercheck.de API +11 |\n| Agent ergonomics | 13% (16.2 this run) | 70 | 84 | registercheck.de API +14 |\n| Security \u0026 auth | 14% (17.5 this run) | 47 | 40 | CompanyLens +7 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 30 | 30 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 3 | 58 | registercheck.de API +55 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 41 | 41 | even |\n| Negative events | ≤15 | 0 | -3 | |\n| **Total** | | **46.7 · D** | **51.6 · D** | |\n\n## Facts side by side\n\n| Fact | CompanyLens | registercheck.de API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | CompanyLens | Openlaw GmbH |\n| Hosted endpoint | `https://mcp.companylens.io/mcp` | `https://api.registercheck.de/v1` |\n| Transports | HTTP, Streamable HTTP | HTTP, Streamable HTTP |\n| Auth | OAuth or key | OAuth or key |\n| Pricing | Freemium | Pay per use |\n| x402 | no | no |\n| Licence | Proprietary service.

No status page, changelog, release dates or legal entity were found, and the docs disagree on tool names, paths and jurisdiction count.\n\n**registercheck.de API.** Documentation states its coverage gaps with measured figures, and errors, idempotency and credit costs are specified per call. A person has to create the account and key, the October renames broke paths in place, and the terms, privacy policy, plan prices and any security policy sit behind a bot check on www.registercheck.de.\n\n## Before you call either\n\n### CompanyLens\n\n1. Call list_jurisdictions first to get valid jurisdiction slugs, then search_companies or get_company\n2. Use get_company, then get_company_section only for the officers or owners you need, and get_company_batch for up to 20 companies\n3. On 429 RATE_LIMITED read Retry-After, which counts to the quota reset and can be hours; check get_usage before a batch\n4. Use the paths in the OpenAPI document (/v1/...), not the /api/v1 paths in llms.txt\n5. Treat company names and officer data as filed by third parties, and check critical facts with the source registry as the terms advise\n\n### registercheck.de API\n\n1. Send the key as `Authorization: Bearer rc_live_…`. Query-string keys and `X-API-Key` are refused\n2. Search first at 1 credit, check `counts` on the company record, then spend 10 credits only on sub-resources that have data\n3. Branch on the problem document's `code`, wait the full `Retry-After` on 429, and stop when a 429 has no `Retry-After`\n4. Send a fresh `Idempotency-Key` UUID on every POST and reuse it on retries\n5. Read `last_register_entry_date` and each shareholding's `source.date`. Shareholder lists can be years old\n\n## Questions\n\n### Which is better for AI agents, CompanyLens or registercheck.de API?\n\nregistercheck.de API scores 51.6 (D) on agent readiness against CompanyLens's 46.7 (D), and leads in 4 of 7 scored categories.
