A one-read dead drop for handing a credential between two agents. Use it when neither side should hold the secret first. POST it, pay once, and receive a URL that works exactly one time — the read destroys it before responding, so a lost response cannot become a second delivery. The reader pays nothing, because a recipient may hold no wallet. Max 4096 bytes. Encrypted at rest with a key returned once and never kept; blind=true stores your own ciphertext untouched.

More from Soren & similar services
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 · AI Judge
soren.com
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 · 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.
