x402 APIPassing, checked 1 h ago

Turns a document into clean Markdown in about a second: pass an https URL or base64 of a PDF, Word, Excel, PowerPoint, HTML, CSV or XML file and get the text back with its headings, tables and page markers, plus the token count. It reads the text layer, so a scanned page with no text layer comes back without text. You are only charged if the Markdown is delivered. No API key, no account.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.01.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://flat-rate-llm.kikoribera03.workers.dev/v1/ai/document?url=https%3A%2F%2Fflat-rate-llm.kikoribera03.workers.dev%2Fm%2Fmuestra-documento.pdf'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://flat-rate-llm.kikoribera03.workers.dev/v1/ai/document?url=https%3A%2F%2Fflat-rate-llm.kikoribera03.workers.dev%2Fm%2Fmuestra-documento.pdf' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
