The REST key travels only in the query string, errors come back as HTTP 200 with a text message, and no status page, SLA or OpenAPI document was found.\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 and plan prices sit behind a bot check on www.registercheck.de.\n\n## Before you call either\n\n### Alpha Vantage\n\n1. Check every 200 response for `Error Message`, `Information` or `Note` keys before parsing data. The API does not signal failures or limits by status code\n2. Budget 25 requests a day on a free key. Real-time, 15-minute delayed and intraday US data, index data and several indicators need a premium plan\n3. Keep `outputsize=compact` unless full history is needed, and ask for `datatype=csv` on long series to cut tokens\n4. Use the hosted MCP server with OAuth at `https://mcp.alphavantage.co/mcp`. The `?apikey=` MCP URL is marked deprecated\n5. Confirm the owner's use is personal and non-commercial, or that a commercial agreement exists, before acting for a business\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, Alpha Vantage or registercheck.de API?\n\nregistercheck.de API scores 52.1 (D) on agent readiness against Alpha Vantage's 41.3 (E), and leads in 5 of 7 scored categories.
