Mercury API not working for you?
- Mercury needs an API key. A 401 or 403 usually means a missing, expired or mis-sent credential: check whether it belongs in a header or the query string.
- A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header.
- If calls fail only in the browser with a CORS error, Mercury may not allow cross-origin requests. Call it from your server instead.
- If it works from one network but not another, check firewalls, VPNs and regional blocks.
- Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.

Mercury API status FAQ
Is Mercury API down right now?
Our latest daily check of Mercury (Oct 24, 2026, 12:25 UTC) failed: its domain name doesn't resolve. One failure can be a blip; the live check below tells you whether it's still failing. This page also runs a live check from our server when you open it, so you can see whether Mercury is responding at this moment.
How do you check whether Mercury API is up?
Once a day our checker requests Mercury's listed URL (https://mercury.postlight.com/web-parser/) and records whether it answers within 15 seconds. Answers like 401 (needs a key), 403 (blocks bots) or 429 (rate-limited) count as up, because the server responded. The listed URL is often the documentation page, so an API endpoint can occasionally fail while its docs stay up.
What can I use if Mercury API is down?
Free Documents & Productivity APIs that were up at their last check include DocStruct, TeamSort, AgentPay Doc Tools. See the full list of Mercury alternatives for a comparison.
Why does Mercury API work for others but not for me?
Mercury needs an API key. A 401 or 403 usually means a missing, expired or mis-sent credential: check whether it belongs in a header or the query string. A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header. If calls fail only in the browser with a CORS error, Mercury may not allow cross-origin requests. Call it from your server instead.
