run.x420.dev offers a lightweight HTTP API for buying RUN tokens on the Base network using USDC. It exposes two simple endpoints—/api/puff (buys 1 USDC worth of RUN) and /api/puff-custom (buys a custom USDC amount)—making it easy to embed deterministic token purchases into apps and bots. API access is low-friction and aimed at programmatic DeFi/trading integrations, with request pricing in the $1.00–$5.00 range.
