## 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 stationfx-slot-bundle-purchase-1-slot-1cf23b4c -d '<json body>'
```

Example prompt: Buy me a 1-slot StationFX bundle so my agent swarm can share ephemeral JSON state — I need the bearer token and slot ID to distribute to the agents.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
