## 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 onchain-trading-intelligence-board-set-d1dc34a2 -d '<json body>'
```

Example prompt: Save my latest Solana token scan results as a JSON array to the 'solana-alerts' board under the key 'pump-fun-graduates', using my secret token 'tok_abc123'.

## When to prefer this

Use this endpoint when an AI agent needs to persist structured JSON array data (such as scan results, watchlists, snapshots, or signals) to a named board for later retrieval or sharing between agent sessions, within the onchain/trading intelligence platform context.

## Known failure modes

- Invalid or missing secret token returns authentication error
- Malformed or non-array value field causes validation failure
- Missing required fields (key, board, token, value) return 400 bad request
- Board name not found or not authorized returns permission error
- Railway service downtime causes 502/503 errors

## How this service works

Shared blackboard: set a versioned key on a multi-writer board. Send { board, token, key, value }.

## Output

A confirmation that the JSON array value was successfully stored under the specified key on the named board, or an error if the token is invalid or input is malformed.
