How it works

01

Request a resource

Your agent sends a standard HTTP request. No API keys, no special headers — just a normal POST with your file.

POST /pdf/compress
Content-Type: multipart/form-data
02

Receive a Challenge

Fylor returns 402 with a WWW-Authenticate Challenge specifying the price and accepted payment methods.

402 Payment Required
WWW-Authenticate: 
  amount=0.05 currency=USD
03

Pay and receive

Your agent pays, resends with a Credential in the Authorization header, and gets the processed file plus a Receipt.

Authorization: <credential>

200 OK
Payment-Receipt: <receipt>

Simple by design

Standard HTTP. Your agent sends a request, gets a 402 Challenge with the price, pays via MPP, and resends with a Credential. The processed file and a Payment Receipt come back.

No API keys. No webhooks. No SDK required. The protocol handles everything in the HTTP layer.

Why Fylor

Built for AI agents

Native MPP (x402) payment flow. Your agent negotiates price and pays programmatically — no dashboards, no manual steps, no human in the loop.

Per-operation pricing

Pay only for what you process. No monthly subscriptions, no minimums, no tiers. Operations start at $0.005 per request.

Every file type

PDF, images, and video in one API. Compress, convert, merge, split, resize, watermark — nine operations and growing.

Fast and reliable

Dedicated workers per file type. Sharp for images, Ghostscript for PDFs, FFmpeg for video. Built for throughput.
