# Saylor Innovations Watchdog API — Base Token Launches

> Saylor Innovations Watchdog API — Base Token Launches is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-30).

Returns a list of newly launched tokens on the Base blockchain along with safety verdicts for each launch

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 saylor-innovations-watchdog-api-base-token-launches-dc74af94
```

Example prompt: Can you pull the latest token launches on the Base blockchain and show me which ones have passed safety checks and which look risky?

## When to prefer this

Choose this endpoint when you need a pre-aggregated, safety-analyzed view of new Base token launches rather than raw on-chain data. It is ideal for agents that need to screen new tokens for rug pull risk, monitor DeFi launch activity on Base, or build watchlists without building custom smart contract analysis pipelines. Prefer it over raw RPC calls when safety verdicts and multi-source aggregation are needed in a single call.

## Known failure modes

- Data sources may be partially unavailable, returning launches from only a subset of sources with failed sources listed in sources_failed
- Empty launches array if no new launches are detected in the current scan window
- Stale or delayed data if upstream blockchain indexers are lagging
- HTTP 402 if the x402 payment of 0.02 USDC is not correctly attached to the request
- HTTP 500 if all upstream sources fail simultaneously

## How this service works

Base Token Launches with Safety Verdicts. Base token launches with safety verdicts: brand-new Base pools (minutes old), dust filtered out, each token scored avoid / high-risk / caution / looks-ok with every reason listed (honeypot, buy/sell tax, owner privileges, holder concentration, liquidity, age) plus pool stats (DEX, age, liquidity, first-hour buys/sells and unique buyers). Up to 20 verdicts per call. Filters: minLiquidity, maxAgeMinutes, limit, safeOnly.

## Output

A JSON object containing a timestamp of when the data was generated, a count of token launches found, the number of pools scanned, an array of launch objects with safety verdicts, a list of data sources that responded successfully, and a list of any sources that failed during the scan.
