Troubleshooting & FAQ

Troubleshooting

HTTP 429 "Too Many Requests"

The API is rate-limited to 60 requests per minute per IP. Add a delay between requests if you're running batch jobs.

posted_date is null

This is not an error — extraction succeeded but no date was determinable. Branch your logic on the reason field, not on posted_date == null.

Slow response (~90 seconds)

Cold URLs that hit the Wayback Machine or the render sidecar can take up to 90 seconds. Set your client timeout to at least 120 seconds.

MCP client can't connect

Verify the URL is exactly https://mcp.whenthisjobwasposted.com/mcp — no trailing slash, no /sse. Make sure your client supports Streamable HTTP transport.

CORS error in browser

The REST API has CORS set to *, so this shouldn't happen. If it does, please report it.

FAQ

Do I need an API key?

No. Both the MCP server and REST API are free and open — no authentication required.

Is there a usage limit?

60 requests per minute per IP address. No daily or monthly cap.

What's the difference between MCP and REST?

MCP is for AI agents that auto-discover tools — your AI learns what the tool does and when to use it. REST is for code and automation that calls a known endpoint directly.

How do I report a bad result?

If you get an incorrect result, report it.
