How this service works
Call when an agent needs input names via input[name] from a public page or HTML (SSRF-safe). Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/css-input-name first.
Output
Returns an array or list of name attribute values found in input elements on the provided page or HTML, enabling agents to understand form structure without manually inspecting markup
Example use cases
Discover login form field names
“I need to know what input field names the login form uses on https://accounts.example.com/login — can you pull out all the input[name] attributes from that page?”
Analyze contact form inputs from raw HTML
“Here's the raw HTML of a contact form — can you extract all the input[name] values from it so I know what parameters to submit? <form><input name="email"/><input name="message"/></form>”
Automate form submission field mapping
“Before I automate submitting this checkout form, I need to map all the field names — can you fetch https://shop.example.com/checkout and list all the input names you find there?”

Side effects
