Meirra
Meirra's REST API (`api.meirra.com/api/v1/...`) covers email verification, company enrichment, lead search, and SEO reporting behind a single `x-api-key` header, confirmed live via a 401 `MISSING_API_KEY` ("API key is required. Include it in the x-api-key header") returned by all four documented endpoints on an unauthenticated POST. `cors` is corrected `yes -> no`: neither that POST nor a separate OPTIONS preflight, both sent with an `Origin` header, returned any `access-control-allow-origin` header, so the API cannot be called cross-origin from a browser. The docs promise no credit card is needed to get API keys and explore the docs, matching the pricing page's "Free Forever" tier alongside paid plans.
GreatAPIs Score
Auth quickstart
- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
