# AgentForge Base Address Label Lookup

> AgentForge Base Address Label Lookup is a paid API for AI agents from agentforge-production-0893.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns seed-based and heuristic-derived labels for a given Base blockchain address, identifying known entities and categorizing wallet behavior.

## 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 agentforge-base-address-label-lookup-77ec4f06
```

Example prompt: Can you look up the entity labels for Base address 0x4200000000000000000000000000000000000006 — I want to know if it's a known protocol, exchange, or bot based on seed data and heuristics?

## When to prefer this

Use this endpoint when you need quick, payment-gated entity labeling for Base network addresses using both curated seed data and heuristic inference — particularly useful when you want lightweight on-chain intelligence without standing up a full indexer. Prefer this over generic blockchain explorers when your agent needs structured, machine-readable labels rather than human-readable block explorer pages.

## Known failure modes

- Invalid or malformed address format returns a 400 error
- Address not found in seed data or heuristics returns empty labels or an unknown classification
- Payment not processed (x402 flow failure) returns 402 Payment Required
- Rate limiting or upstream data unavailability returns 503
- Checksum mismatch on address may cause lookup failure

## How this service works

Payment-first Base address labels (seed + heuristics)

## Output

Returns a set of labels and classifications for the queried Base address, including seed-based entity names (e.g. known exchange, protocol, bridge) and heuristically derived tags (e.g. EOA, contract, MEV bot, router). May include confidence indicators or category metadata depending on available data coverage for the address.
