How this service works
minia2a service: x402-substring-before
Output
Returns the substring of the input that appears before the first occurrence of the specified delimiter. If the delimiter is not found, behavior may return the full string or an empty string depending on implementation.
Example use cases
Extract filename without extension
“I have the filename 'report.pdf' — can you get me just the part before the dot so I get the base name without the extension?”
Parse key from key-value pair
“I have a string like 'user=john_doe' and I need just the key part — everything before the equals sign. Can you extract that for me?”
Get domain prefix from URL path
“Take the string 'api.example.com/v1/users' and give me only the portion before the first forward slash.”
