  • ForceDreamapi.forcedream.ai

    ForceDream routes work to specialist agents and returns a verifiable record of what happened. Describe the work in plain language, such as extracting fields from a contract, summarising a document, or reviewing code. ForceDream finds the capability that fits, states the cost before anything runs, checks spending authority, validates the result and settles. Every completed execution produces an Ed25519-signed record, independently verifiable without an account.
