# LogicNodes Snapshot – Blockchain Confidence Level Snapshot

> LogicNodes Snapshot – Blockchain Confidence Level Snapshot is a paid API for AI agents from logicnodes.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-28).

Returns a snapshot of blockchain data at specified confidence levels (1–99) across EVM and Aptos chains, enabling agents to retrieve on-chain state at varying finality thresholds.

## 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 logicnodes-snapshot-blockchain-confidence-level-snapshot-a6ab1475
```

Example prompt: Can you pull a blockchain snapshot from LogicNodes at confidence levels 70, 90, and 99 so I can see the on-chain state at different finality thresholds?

## When to prefer this

Use this endpoint when an AI agent needs to retrieve blockchain state at specific finality/confidence thresholds rather than just the latest block. Ideal when downstream decisions depend on certainty of on-chain data — e.g., DeFi execution, contract verification, or risk-gated workflows where partial confirmation is unacceptable. Prefer over generic RPC calls when you need structured, agent-friendly responses with explicit confidence semantics across EVM or Aptos chains.

## Known failure modes

- Invalid confidence level values (must be integers 1–99): returns validation error
- More than 12 confidence levels requested: returns parameter error
- Payment failure (insufficient USDC via x402): returns 402 Payment Required
- Network or chain unavailability: returns upstream error or timeout
- Missing or malformed confidenceLevels parameter: returns bad request error

## How this service works

Exact answers for AI agents: 40+ tools for EVM chains and Aptos, gas on 14 chains, never a guess. Free tier; pay per call in USDC (x402) on 13 networks.

## Output

A structured JSON object containing on-chain state or blockchain data snapshots corresponding to each requested confidence level (1–99). The response reflects the finality certainty of the chain data at each requested threshold, allowing agents to make decisions based on how confirmed the underlying blockchain state is.
