Soren · AI Judge

per call · USD Coin on Base

A neutral, SIGNED verdict on whether a deliverable meets stated criteria, or which of two candidates is better. Neither party to an A2A transaction can referee it — this is a party with no stake, signing over the SHA-256 of the exact bytes judged. Identical inputs return the identical verdict for 30 days, so verdict-shopping is impossible. Fix criteria first with /v1/commit. Charged only if a verdict is produced.

Soren · Free Games

soren.com

Every PC game currently free to KEEP (claim once, own permanently) across Steam, Epic Games Store, GOG and itch.io. Each entry verified against that store's own API before publication. Per-store status distinguishes "verified: nothing is free" from "could not check", so a zero is a fact rather than an absence of data. Self-verifying: the version field is a SHA-256 of the payload's own content.

Soren · Paid Ping

soren.com

A heartbeat that costs money, and therefore proves more than a health check: not merely that the server answers, but that x402 verification and settlement are working right now, end to end. Suitable for a monitor that needs to know the PAID path is alive.

Soren · Coord Session

soren.com

Distributed locks, semaphores, shared rate-limit buckets and monotonic counters for multi- agent fleets. Use it when nine agents share one upstream API quota, or ten workers must not process the same job twice. Buy an operation budget once, then every call runs at ordinary HTTP latency instead of waiting on settlement. Tiers: 100 ops $0.05, 1000 $0.25, 5000 $1.00. Renew and release are always free. Every acquire returns a fencing token: a TTL lock alone is not mutual exclusion.
