unprobed

SFX Slots: ephemeral shared JSON state for AI agent swarms. Buy a slot bundle via x402, share the token and slot IDs with your swarm. Each slot holds up to 4KB of JSON. Read, write and coordinate without a database.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
