> Base Launch Radar – Latest Token Launches is a paid API for AI agents from base-launch-radar.vercel.app, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

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 base-launch-radar-latest-token-launches-f8d86105
```

Example prompt: Show me the latest Base token launches — filter to HOT tier only, up to 20 results, and only include ones with a safety score of at least 65.

## When to prefer this

Use this endpoint when you need a pre-scored, ready-to-act ranked list of new Base token launches with safety and momentum signals in a single call, rather than fetching raw on-chain data and scoring it yourself. Ideal for agents monitoring the Base ecosystem for new opportunities or risks without building their own scoring pipeline.

## Known failure modes

- Invalid tier value (not HOT/WATCH/AVOID) returns a validation error
- Limit out of range (< 1 or > 50) returns an error
- minSafety value outside 0-100 returns a validation error
- No launches matching the filters returns an empty list
- Payment not processed (x402) returns 402 Payment Required
- Service temporarily unavailable returns 5xx error

## How this service works

Scored intelligence on freshly-launched Base tokens: safety + momentum → composite score and an AVOID/WATCH/HOT decision per launch. One call returns a ranked list.

## Output

A ranked list of recently launched Base tokens, each with a safety score, momentum score, composite score, and a tier classification of AVOID, WATCH, or HOT — ordered so the most promising launches appear first.
