## 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 blockchain-iq-all-21-chains-research-digest-7cd15932
```

Example prompt: Pull the Blockchain IQ digest covering all 21 chains — I want the analyst summaries, transaction trends, fees, and value moved for Bitcoin, Ethereum, Solana, Base, Arbitrum, XRP Ledger, BNB, TON, and the rest in one shot.

## When to prefer this

Choose this endpoint when you need a broad, analyst-curated overview of all 21 major blockchains in a single call without specifying any parameters. It is ideal for daily briefings, cross-chain comparisons, and monitoring the crypto ecosystem holistically. Prefer the single-chain 'Blockchain Network Activity' or 'Crypto Coin Research Brief' endpoints when you only need data for one specific chain or coin.

## Known failure modes

- Payment failure (402): USDC payment of $0.05 not provided or rejected
- Service unavailable (5xx): upstream data pipeline or site outage
- Empty or stale data: research not yet refreshed for the current period
- Rate limiting: too many rapid consecutive calls

## How this service works

Blockchain IQ research on all 21 tracked blockchains in one parameter-free call: each chain's analyst lede and dated 'what the chain data shows' section (transactions, senders, fees, value moved against four weeks and a year earlier), with links to the full brief and the chain's dashboard. Bitcoin, Ethereum, Solana, XRP Ledger, Base, Arbitrum, BNB, TON and more. JSON, no API key. $0.05 per call. Blockchain IQ.

## Output

A JSON object containing, for each of the 21 tracked blockchains, an analyst lede, a dated 'what the chain data shows' section covering transactions, active senders, fees, and value moved (benchmarked against four-week and one-year prior periods), plus links to the full research brief and the chain's analytics dashboard.
