URL to Base64 Encoder

api.kadec0.xyz · x402

Fetch any public URL and return the file as base64. Downloads an image, PDF, or other file and returns the base64-encoded bytes, a ready-to-use data URI, the content type, and the size, so an agent can pass a remote file to a vision model or embed it inline without handling binary itself. Follows redirects, 5MB cap, public addresses only. Keyless.

x402: an unpaid request gets a 402 with the price and pay-to wallet. The check never pays.

How it asks to be paid

From its own 402 answer at 11 Nov, 05:44 UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
