# Soren Commitment Reveal (Open)

> Soren Commitment Reveal (Open) is a paid API for AI agents from soren.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).

Opens a sealed commitment token to verify whether the revealed preimage matches what was originally committed, returning a signed statement with match/mismatch result and seal duration.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability soren-commitment-reveal-open-3b7c9bed
```

Example prompt: Open my Soren commitment token '<commitment token>' with the original preimage 'my sealed bid: 4200' and give me the signed proof showing whether it matches and how long it was sealed.

## When to prefer this

Use this endpoint when you need a cryptographically signed, oracle-backed proof of whether a preimage matches a sealed commitment — especially for settling sealed-bid auctions, resolving fair-play disputes, or producing verifiable evidence of prior knowledge. Unlike self-verified commitment schemes, Soren signs both match and mismatch outcomes, making it suitable for adversarial contexts where one party may act dishonestly. Prefer this over custom hash-based solutions when you need an independent third-party signed attestation that can be verified externally via soren.com/oracle-key.json.

## Known failure modes

- Invalid or expired commitment token returns an error
- Preimage exceeds 2048 character limit
- Commitment token already opened (replay attempt)
- Payment not settled (x402 payment required at $0.02 USDC)
- Preimage does not match but a signed mismatch proof is still returned (not a failure per se — this is by design)

## How this service works

Open a commitment issued by /v1/commit and receive a signed statement that the value matches what was sealed, and how long it was sealed for. A MISMATCH IS ALSO SIGNED, so an honest party can prove the other side produced something different from what it committed to. Use it to settle sealed bids and fair-play disputes. Verify with soren.com/oracle-key.json

## Output

A signed statement from Soren's oracle (verifiable at soren.com/oracle-key.json) indicating whether the supplied preimage matches the original committed value, whether the result is a MATCH or MISMATCH (both outcomes are signed), and the duration for which the value was sealed.
