Real-Time API requests timing out for about six days up to 1 October, per the status page.\n\n**RocketReach API.** The hosted MCP server has nine documented tools, OAuth 2.1 with dynamic client registration and machine-readable error codes, and searches cost no credits. Plan prices were not readable, the docs send API plan requests to email, the terms require a human account holder, and the `account` tool returns the account's API key to the model.\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. Use base records at 10 credits when you don't need the 20-credit multi-source fields\n3. Use MCP v2 at /mcp/v2. The older /mcp endpoint will be deprecated\n4. Treat a 402 as out of credits, not a transient error\n5. Expect no work emails for EEA and UK people from the MCP email tool\n\n### RocketReach API\n\n1. Search first with `person_search` or `company_search`, which cost no credits, then look up only the profile IDs needed\n2. Treat `status: \"pending\"` as normal. Poll `check_person_status` after at least 3 seconds, and polling is free\n3. Do not echo the `account` tool's output to users or logs. It includes the account's API key\n4. Send the key in the `Api-Key` header. The `api_key` query parameter is deprecated\n5. Bulk lookup takes 1 to 100 queries and needs a webhook. Results arrive at the webhook, signed in `X-RocketReach-Signature`\n6. Do not loop on `unknown` from `email_verify`, or on `lookup_failed` and `not_found`. The last two are terminal\n\n## Questions\n\n### Which is better for AI agents, Coresignal API + MCP or RocketReach API?\n\nCoresignal API + MCP scores 62.9 (B) on agent readiness against RocketReach API's 51.2 (D), and leads in 6 of 7 scored categories. RocketReach API leads on reliability.\n\n### Do Coresignal API + MCP and RocketReach API 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 RocketReach API without installing anything?\n\nYes.
