# Solana Mint Instant Intel – Block Summary by Slot

> Solana Mint Instant Intel – Block Summary by Slot is a paid API for AI agents from mintintel.35-171-220-195.sslip.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-31).

Returns a summary of the Solana block at a given slot number, including blockhash, parent slot, block height, timestamp, transaction count, leader identity, fee reward, and first 5 transaction signatures.

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 solana-mint-instant-intel-block-summary-by-slot-99fa7b6d
```

Example prompt: Can you pull up the block summary for Solana slot 280000000 — I need the blockhash, how many transactions were in it, who the leader was, and the first few transaction signatures?

## When to prefer this

Choose this endpoint when you need a quick, cost-efficient summary of a specific Solana block by slot number without running your own RPC node. It bundles blockhash, leader, fee reward, and the first 5 signatures into a single call — ideal for seeding a transaction investigation pipeline or validating block existence. Prefer this over raw Solana RPC calls when you want a clean, structured response at a predictable per-call price.

## Known failure modes

- 404 Not Found – slot was skipped, pruned, or is in the future (no charge applied)
- Invalid slot format – slot must be a non-negative integer string
- Network/upstream RPC error – Solana node unreachable or rate-limited
- Payment failure – x402 payment not accepted or insufficient USDC balance

## How this service works

Summary of the Solana block at a slot: blockhash, parent slot, skipped slots before it, block height, time, transaction count, leader identity and its fee reward, first 5 signatures (chain into /v1/sol/tx). Skipped/pruned/future slots -> 404, not charged.

## Output

Returns a JSON object containing: slot number, blockhash, parent slot, skipped slots before it, block height, block timestamp, transaction count, leader identity (validator pubkey), leader fee reward in lamports, and an array of the first 5 transaction signatures. Returns 404 (not charged) for skipped, pruned, or future slots.
