## 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 relaystation-storage-pass-7e1ff253 -d '<json body>'
```

Example prompt: Pass the signed contract PDF I just stored to the client — create a one-time download link that burns after they open it, no account needed on their end.

## When to prefer this

Choose this endpoint when you need to hand off a file to a recipient (human or agent) who has no account on the platform, requires no persistent access, and where single-use burn-after-read security is important. Ideal for agent-to-agent pipeline handoffs, secure client document delivery, or any scenario where a permanent share link would be a security risk. Prefer over generic cloud storage share links when you need automatic token invalidation after first use.

## Known failure modes

- Invalid or expired file reference — token cannot be created for a non-existent or already-expired file
- Insufficient balance — caller's Relaystation balance below $0.01 minimum
- Token already consumed — attempting to reuse a burned token returns an access-denied error
- Missing required file scope or reference parameter — returns a 400 validation error
- Rate limiting or quota exceeded on the Relaystation account

## How this service works

Hand a file to another agent or person — scoped, read-capped share tokens that burn once consumed. From $0.001; no account for the recipient. Part of Relaystation: 155 agent tools on one balance — storage, e-sign, KYC, PDF/data/media, sub-cent LLM. relaystation.ai

## Output

Returns a scoped, single-use share token or URL that grants the bearer one-time read access to the specified file. The token burns (becomes invalid) after the first successful consumption, and the recipient requires no Relaystation account.
