# Pontica

> Pontica is a market for inference on Robinhood Chain (chain id 4663). OBOL credits (ERC-20, 6 decimals) are minted at $1 against USDG, traded below $1 on an onchain discount book, and activated into an API balance: 1 OBOL is $1 of inference at OpenRouter's list price, on any model OpenRouter serves. A wallet signs one Sign-In with Ethereum message for an API key and calls every model through one OpenAI compatible endpoint at https://pontica.gg/api/v1. Anyone can also fund an agent or an open AI project in OBOL through AI Funding, with a goal, a deadline, refunds if it misses and a daily allowance.
