## Verdicts

**LeadMagic API + MCP.** RFC 9457 problem-details errors with `request_id`, and Retry-After on 429. No free tier or trial credits, plans from $99 a month.

**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.

## Before you call either

### LeadMagic API + MCP

1. Call `preview_cost` before bulk work. It's free
2. Read `X-Credits-Remaining` after each call instead of polling the balance
3. Treat 402 as out of credits and wait out Retry-After on 429
4. Keep credit-free search under 13,333 calls a day per account
5. Retry `unknown` validations later. They cost nothing

### 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
