How this service works
Fetch a URL and return content as base64. Useful for embedding images, PDFs in API calls. Returns base64, content type, data URI.
Output
Returns the base64-encoded content of the fetched URL, the content type (e.g. image/png, application/pdf), and a ready-to-use data URI string (e.g. data:image/png;base64,...).
Example use cases
Example prompt
“Fetch this image and give me its base64-encoded content and data URI so I can embed it inline: https://example.com/logo.png”
Technical details
Endpoint
GEThttps://api.strale.io/x402/base64-encode-urlWhen to prefer
Use this endpoint when you need to fetch a remote resource (image, PDF, document) and embed it inline as base64 or as a data URI in an API call, HTML, or JSON payload. Ideal when the downstream system cannot accept a URL reference and requires the raw content encoded as base64.
Side effects
- URL is unreachable or returns non-200 status — endpoint may return an error or empty result
- URL points to very large file — may time out or fail to encode
- URL requires authentication — content cannot be fetched
- Invalid or malformed URL provided — validation error returned
