# Pulse API – Base Token Preflight Due-Diligence Report

> Pulse API – Base Token Preflight Due-Diligence Report is a paid API for AI agents from pulse-api-production-7aae.up.railway.app, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-13).

Generates a Grok-synthesized due-diligence report on a Base chain token, combining live contract analysis, market data, holder distribution, project website, social profiles, and promotion evidence into a structured risk assessment.

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 pulse-api-base-token-preflight-due-diligence-report-daec9de1 -d '<json body>'
```

Example prompt: Run a full due-diligence preflight check on the Base chain token at contract address 0x1234abcd... — I want to see the contract evidence, market data, holder distribution, social profiles, and whether there's any suspicious promotion activity before I buy.

## When to prefer this

Choose this endpoint when you need a comprehensive, AI-synthesized due-diligence report on a Base chain token that combines on-chain contract analysis with off-chain signals (social, website, promotions) in a single call. Prefer it over generic blockchain explorers when you want an opinionated risk summary rather than raw data, or when you need to cross-reference contract evidence with social promotion patterns to detect coordinated pump-and-dump activity.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty report
- Token not deployed on Base chain causes lookup failure
- Rate limiting or payment failure (insufficient USDC balance) blocks the request
- Grok synthesis timeout if external data sources are slow or unavailable
- Social/website data unavailable for very new or obscure tokens

## How this service works

A Grok-synthesized token due-diligence report using live contract, market, holder, project website, social-profile and promotion evidence. Raw contract evidence and exact transaction simulation remain free.

## Output

A structured Grok-synthesized due-diligence report covering: raw contract evidence and code analysis, transaction simulation results, live market data, holder distribution breakdown, project website assessment, social profile evaluation, and promotion/shill activity detection — with an overall risk assessment for the queried Base chain token.
