# Chain Pulse — Blockchain Network Activity Monitor

> Chain Pulse — Blockchain Network Activity Monitor is a paid API for AI agents from the-stall.intuitek.ai, paid per call via x402, $0.059/call, status unknown (last checked 2026-09-13).

Returns real-time pulse/health metrics for blockchain networks, such as transaction throughput, block times, gas prices, or congestion signals.

## Facts

- Endpoint: GET https://the-stall.intuitek.ai/cap/chain-pulse
- Price: $0.059/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/chain-pulse-blockchain-network-activity-monitor-159251e3
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_urFVEG02sKgpw1TVkyUO7

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 chain-pulse-blockchain-network-activity-monitor-159251e3
```

Example prompt: Can you check the current pulse of the Base mainnet — I want to know how active the chain is right now, including things like block activity or congestion?

## When to prefer this

Choose this endpoint when an agent needs a quick, keyless, pay-per-call snapshot of blockchain network health or activity without setting up accounts or subscriptions — especially useful for Base mainnet monitoring given the native USDC payment integration.

## Known failure modes

- Unsupported chain identifier returns an error or empty result
- Malformed properties filter leads to a 400-level response
- Network unavailability causes timeout or 5xx error
- Payment failure (insufficient USDC or x402 handshake issue) blocks the request

## How this service works

Returns an Ethereum block header + current stablecoin depeg status in one call. Collapses the eth-block → stablecoin-watch 2-hop chain. Block fields: number, hash, miner, timestamp, gas_used, tx_count. Stablecoin fields: symbol, price, peg_deviation, depeg_status, composite alert level. Supports Ethereum, Base, Polygon, Arbitrum. Free upstreams (DRPC + DeFiLlama), no API key required.

## Output

Returns a snapshot of blockchain network activity metrics for the requested chain, potentially including block throughput, transaction counts, fee levels, and overall network health signals — paid via USDC on Base mainnet at $0.006 per call, no API key needed.
