Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 losbeto-subscribe-whale-00299366
```

Example prompt: Sign me up for the whale subscription tier on Losbeto so my trading agent gets alerts whenever large wallets make big moves on Solana or Base — I want to pay with USDC.

## When to prefer this

Choose this endpoint when an AI trading agent or automated system needs to subscribe to high-value on-chain whale activity monitoring across Solana and Base, and is willing to pay $19.99 USDC via the x402 micropayment protocol. Prefer this over cheaper tiers when the agent requires whale-level signal fidelity rather than standard market data.

## Known failure modes

- Insufficient USDC balance to cover $19.99 payment — returns payment required error
- Invalid or missing wallet address input — returns validation error
- Chain not supported or misconfigured — returns unsupported network error
- Subscription already active for the requesting agent — may return conflict or duplicate error
- Malformed input properties field — returns schema validation error
- Service unavailable or rate limit hit — returns 5xx or 429 error

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana and Algorand via x402.

## Output

A JSON response confirming subscription activation, likely including a subscription ID, tier details, coverage chains (Solana, Base), and access credentials or webhook endpoint for receiving whale-level on-chain alerts.
