## Which one, for what

### Prospeo API + MCP (D)

Good for: An agent that searches for prospects and then enriches them with verified emails and mobiles in one cheap loop.

Ahead on:
- Agent ergonomics, 79 against 72
- Security & auth, 54 against 34
- Payments & pricing, 40 against 10

Also in its favour:
- Runs on your own machine

Watch for: No status page, SLA or changelog

### RocketReach API (D)

Good for: Teams that already hold a RocketReach plan and want an agent to search people and companies, reveal emails and phones, and verify single addresses over MCP.

Ahead on:
- Reliability, 64 against 35
- Schema & documentation, 72 against 61
- Transparency & trust, 58 against 42

Watch for: The pricing page is drawn by script and was not read, and the docs tell users without a paid plan to email for an API plan

## Verdicts

**Prospeo API + MCP.** MCP tool descriptions say when to use each tool, its credit cost and the next call. No status page, SLA or changelog.

**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.

## Before you call either

### Prospeo API + MCP

1. Call `search_suggestions` before using location, technology or industry filters, or the search returns nothing
2. Pass `person_id` values from search into `bulk_enrich_person`, 25 at a time
3. Branch on the body `error_code`, not the HTTP status, which is 400 for most failures
4. Set `enrich_mobile` only when needed. A mobile costs 10 credits against 1 for an email
5. Use Enrich Person. The old Email Finder endpoint was removed in March 2026

### RocketReach API

1. Search first with `person_search` or `company_search`, which cost no credits, then look up only the profile IDs needed
2. Treat `status: "pending"` as normal. Poll `check_person_status` after at least 3 seconds, and polling is free
3. Do not echo the `account` tool's output to users or logs. It includes the account's API key
4. Send the key in the `Api-Key` header. The `api_key` query parameter is deprecated
5. Bulk lookup takes 1 to 100 queries and needs a webhook. Results arrive at the webhook, signed in `X-RocketReach-Signature`
6. Do not loop on `unknown` from `email_verify`, or on `lookup_failed` and `not_found`. The last two are terminal
