Returns a short version of the Snekfun protocol configuration — fees, limits, and core bonding-curve parameters used by the builder. The response is built from raw values in the protocol config plus the launch script hash from the contracts config. Poll periodically if you cache fee-sensitive calculations client-side.
GET /parameters returns a shortened response. For the full source data, see Protocol config and Contracts config. The deployScript field comes from contracts.launchAsset.hash.
