> Nansen Address Current Balance is a paid API for AI agents from api.nansen.ai, paid per call via MPP or x402, $0.01/call, status unknown (last checked 2026-09-14).

## Facts

- Endpoint: GET https://api.nansen.ai/api/v1/profiler/address/current-balance
- Price: $0.01/call
- Payment: MPP, x402
- Status: unknown
- Last checked: 2026-09-14

## 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 api-nansen-ai-575979f8
```

Example prompt: What tokens and coins does wallet 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE currently hold? Pull the current balance data from Nansen.

## When to prefer this

Use this endpoint when you need the live, current-state portfolio snapshot of a specific wallet address and want Nansen's enriched wallet labeling context (e.g. identifying smart money, entity names). Prefer over generic RPC balance calls when you want aggregated multi-token balances with Nansen's analytics layer. Use Historical Balances sibling endpoint if you need balance changes over time rather than current state.

## Known failure modes

- Invalid or malformed address returns 400 error
- Address not found or never active on supported chains returns empty result
- Unsupported blockchain network returns error
- Rate limit exceeded returns 429
- Authentication or payment failure returns 401/402
