Ocean Protocol

Pricing model: Pay-as-you-go (per-asset tokenized pricing)

Overview: Ocean Protocol uses per-asset pricing set by publishers. Two official pricing schemas are provided on the vendor site: "fixed pricing" (publisher sets a token price for a datatoken) and "free pricing" (a dispenser dispenses datatokens at no cost). Payments and fees are denominated in OCEAN or any ERC20 token configured when the asset is published. Datatokens represent access rights and are created automatically when publishing an asset.

Free tier/trial: Publishers can configure a dispenser (free pricing) that dispenses datatokens at price 0 (free access). Publishing on Ocean Market currently has no publish fee.

Example costs & official examples from vendor docs:

• Dispenser / Free pricing: price = 0 (dispenser). (Docs example in DDO specification showing a dispenser price of "0").
• Fixed-rate example: price = 1 (token) in DDO example (a fixedrate price of "1" is shown in the DDO sample in the official docs).
• Provider compute example: 1.0 OCEAN per minute (example value shown under Provider fees in the official docs).
• Ocean Community fee collected on consumption: 0.03 DT (documented smart-contract-level fee).
• Swap fees (smart-contract-level examples): 0.1% for OCEAN/H2O; 0.2% for other ERC20 tokens (documented in Fees page).

Discounts / other: Publishers/marketplaces control absolute consume fees and provider fees (absolute amounts, token choice); marketplaces may set their own per-order fees. No central subscription discounts apply — pricing is set per-asset and per-provider by publishers/market owners.

Notes / constraints: All fees and pricing elements (publish fee, consume fees, provider fees, Ocean community fee, swap fees) are configurable in markets and smart contracts; many sample values are provided in the docs but actual prices depend on the asset publisher, provider operator, and market configuration.
