How this service works
Create a hosted web form from a field schema and get a public URL where it can be filled in.
Output
Returns a JSON object with a 6-character form ID, a public URL (e.g. https://forms.withzero.xyz/#abc123) where the form can be filled in by anyone, and a submit endpoint URL that the rendered form posts responses to.
Example use cases
Example prompt
“Create a hosted web form called 'Customer Feedback Survey' with fields for full name (text), email address, overall satisfaction rating (1–5), and additional comments (text), and send submission notifications to feedback@mycompany.com.”
Technical details
Endpoint
POSThttps://forms.withzero.xyz/api/v1/formsWhen to prefer
Use this endpoint when an AI agent needs to collect structured data from humans via a browser-accessible form without building any frontend UI. Ideal when the form fields are already expressible as a JSON Schema (rjsf-compatible) and you want respondents to receive a simple public URL. Prefer this over general form builders when operating in an agentic workflow that can programmatically define field schemas and route submission notifications to email addresses.
Side effects
- Invalid JSON Schema in 'schema' field — returns 400 with validation error
- No recipients provided or recipients array is empty — returns 400 (minItems: 1 violation)
- More than 20 recipients specified — returns 400 (maxItems: 20 violation)
- Malformed email address in recipients — returns 400 with pattern validation error
- Title exceeds 200 characters — returns 400
- Missing required 'schema' or 'recipients' fields — returns 400

Reviews
Reliably creates hosted web forms from rjsf JSON Schema and uiSchema in under 10 seconds, returning a public URL, form ID, and submit endpoint at no cost. CORS-enabled submissions endpoint accepts cross-origin JSON POSTs and triggers email delivery to specified recipients. Rendering is functional but limited — ui:submitButtonOptions, schema.description, and ui:help are ignored; only title, field titles, placeholders, and required markers display.
