Tools 12 found in our last check

  • commit_input

    Commit your sealed input as a hash (sealed mode). Nobody — including redeal — can see your input until all parties have committed. After the last commitment the deal opens for reveals immediately.

  • compute_commitment_tool

    Compute a commitment string for (input, salt): sha256(JCS(input) ++ salt_bytes), prefixed 'sha256:'. Convenience only — the rule is public and you can compute it yourself.

  • create_deal

    Create a fairness deal. You are party 0 (initiator). Returns a deal id and one invite token per party — give each counterparty their own token. Sealed mode: everyone commits a hash, then reveals; certificate is issued automatically when the deal computes or goes VOID.

  • create_key

    Get a free redeal API key. No signup, no email — this is the entire onboarding. The key is shown once; store it. Use it as api_key in create_deal.

  • get_certificate

    Fetch the signed fairness certificate for a finished deal (state CERTIFIED). Includes the labelled signature (es256 or ed25519) and transparency-log inclusion proof. Verify it with verify_certificate.

  • get_deal

    Read a deal's public state: protocol state (OPEN/COMMITTING/REVEALING/CERTIFIED/VOID/EXPIRED), who has committed/revealed, deadlines, result, and certificate_id once issued. Inputs of other parties are never exposed.

  • get_entropy

    Finish a random.v1 deal once every party has revealed: redeal fetches the deal's pre-declared drand round from the public League of Entropy beacon (fixed at creation, publicly cross-checkable), computes the draw, and issues the certificate. Call this after the last reveal_input;…

  • get_public_certificate

    Fetch a certificate's full JSON (outcome included) by id. Works for public deals (the default). Parties-only deals and unknown ids both return NOT_FOUND. To re-verify the computation itself, use verify_certificate (checks) or the CLI re-runner with the parties' inputs.

  • list_algorithms

    List redeal's algorithms (split.v1 fixed-budget fair division, random.v1 verifiable random selection, shapley.v1 Shapley shares, auction.v1 sealed-bid second-price auctions) with their input contracts and the published test vectors (served inline — the same fixtures the engine t…

  • reveal_input

    Reveal your committed input. It must hash to your earlier commitment. When the last party reveals, the deal computes and the fairness certificate is issued automatically — fetch it with get_certificate.

  • validate_input

    Validate your algorithm input against the deal's contract BEFORE you commit. A commitment binds the exact input bytes — a contract-violating input (e.g. split.v1 valuations not summing to exactly 1000) can never be corrected afterwards and the deal will VOID at the reveal deadli…

  • verify_certificate

    Verify a redeal certificate by id: signature check (current or published legacy key) + transparency-log inclusion check, reported per check. Free, no credential required, always.
