# Heurist Mesh: USDC Hourly Pair Activity (Solana)

> Heurist Mesh: USDC Hourly Pair Activity (Solana) is a paid API for AI agents from mesh.heurist.xyz, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Reports hourly USDC transfer volume between two specific Solana addresses, broken down by direction (A→B and B→A), to analyze flow intensity between wallets.

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 heurist-mesh-usdc-hourly-pair-activity-solana-c2ceeb0f -d '<json body>'
```

Example prompt: Show me the hourly USDC transfer breakdown between Solana wallets 7xKp...aB1c and 3mNq...Rz9w for the past 7 days — I want to see how much flowed in each direction per hour to figure out if these two wallets are coordinating.

## When to prefer this

Choose this endpoint when you need directional, time-bucketed USDC flow analysis specifically between two known Solana wallet addresses — particularly for forensic investigation of suspected related wallets, wash trading detection, or auditing scheduled fund routing. Prefer this over general wallet transaction endpoints when the pair relationship and hourly granularity are what matter.

## Known failure modes

- Invalid or non-existent Solana wallet addresses return an error or empty dataset
- No transfer activity in the requested time window returns empty hourly buckets
- Rate limiting or payment failure (x402) if USDC balance insufficient
- Very long time ranges may time out or return truncated results
- Addresses with extremely high transaction volumes may cause slow responses

## How this service works

Report hourly USDC transfer activity between two specific addresses, showing volume in each direction (A→B and B→A) per hour. Use to analyze flow intensity between suspected related wallets.

## Output

Returns a time-series of hourly buckets, each showing the USDC volume transferred from address A to address B and from B to A within that hour, enabling directional flow analysis and identification of transfer intensity patterns between the two wallets.
