How this service works

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.

Output

Returns a JSON object containing: a JWT bearer token (to be passed as Authorization: Bearer <token>), an array of slot IDs the swarm can read/write, total read+write op limit across all slots, slot count, duration in hours (24h TTL), expiry timestamp in ISO-8601 format, and the USD amount paid.

Example use cases

Multi-agent pipeline shared memory

“Spin up a StationFX 1-slot bundle for my data processing swarm — they need a shared place to write intermediate JSON results and coordinate which tasks are done, and I want the token and slot IDs to hand out to each agent.”

Temporary task queue coordination

“Buy a StationFX ephemeral slot so my parallel research agents can share a running task list — each one should be able to read and update the same JSON without stepping on each other, and the 24-hour TTL is plenty.”

Short-lived agent handoff state

“I'm running a two-agent workflow where agent A produces a JSON summary and agent B consumes it — grab a StationFX slot bundle and give me the token and slot ID so I can wire up the handoff.”

When to prefer

Choose this endpoint when you need lightweight, ephemeral, schema-free shared state for a coordinating swarm of AI agents and want to avoid provisioning a full database. Ideal for short-lived pipelines (24h TTL), small payloads (up to 4KB per slot), and pay-per-use agentic workflows that require no persistent infrastructure. Prefer alternatives (e.g. a real database or Redis) when you need persistence beyond 24 hours, payloads larger than 4KB, or complex querying.

Side effects

Payment failure via x402 — insufficient funds or invalid payment header returns payment error
Malformed POST body — missing required fields returns 400 Bad Request
Service unavailability — slot provisioning backend down returns 5xx
Slot quota exceeded on provider side — may return resource limit error
Expired or invalid x402 payment token — returns 402 Payment Required
