Get started with Obol

Obol is pay-per-token AI access, settled on Arc. Buyers route many models through one OpenAI-compatible endpoint and pay per token in USDC. Providers run nodes that serve models and earn per token. Pick your path.

For builders

Buy inference

Connect, fund USDC on Arc, get an API key, and make your first metered call from any OpenAI-compatible tool.

For providers

Run a node

Point a node at any OpenAI-compatible backend, prove ownership, pass the canary, and earn USDC per token.

30-second quickstart

Already have a key? Obol speaks the OpenAI API — change one base URL and one key. Point your tool at the Obol backend (not the web dashboard):

bash

curl https://obolservice.onrender.com/v1/chat/completions \
  -H "Authorization: Bearer $OBOL_KEY" \
  -H "content-type: application/json" \
  -d '{"model":"auto","messages":[{"role":"user","content":"Hello from Obol"}]}'

model: "auto" lets Obol route to the cheapest capable model within your budget. Response headers report the route and exact cost.
