x402 APIPassing, checked 1 h ago

Describe a job in plain words and it gets done in ONE paid call: picks the right tools from 71 capabilities - transcription, translation, documents, images, web, on-chain, domains, IPs, weather, FX - fills their parameters and chains up to 3 steps, feeding each result into the next. Priced per job: the 402 challenge quotes YOUR job before you sign, from $0.02. You pay for not having to know which tool or which order. If nothing fits, nothing is charged.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.035.

# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://flat-rate-llm.kikoribera03.workers.dev/v1/do?input=https%3A%2F%2Fflat-rate-llm.kikoribera03.workers.dev%2Fm%2Fmuestra-voz.wav&job=transcribe+this+audio+and+give+me+the+key+points'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
