# Token Due Diligence Batch API (token-dd/batch)

> Token Due Diligence Batch API (token-dd/batch) is a paid API for AI agents from api.firstmention.uk, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Performs batch due diligence risk scoring on multiple crypto tokens across chains, returning verdicts, red flags, and liquidity data for each.

## Facts

- Endpoint: GET https://api.firstmention.uk/s/token-dd/batch?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-29
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/token-due-diligence-batch-api-token-dd-batch-87986c67
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_nwW1YJs-zY7IiyCTyse1b

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 token-due-diligence-batch-api-token-dd-batch-87986c67
```

Example prompt: Can you run a batch due diligence check on these two tokens for me — AERO on Base at 0x940181a94a35a4569e4529a3cdfb74e38fd98631 and USDC on Ethereum at 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 — and tell me their risk scores and any red flags?

## When to prefer this

Use this endpoint when you need to assess the safety or risk of one or more token contracts in a single call, especially when screening before a swap, investment, or airdrop claim. It aggregates on-chain RPC data, GoPlus security signals, and DexScreener liquidity into a single risk verdict, saving the agent from calling multiple data sources separately. Prefer it over single-token endpoints when evaluating multiple tokens at once.

## Known failure modes

- Missing or malformed chain/address query params returns an error
- Invalid chain identifier not recognized by the service
- Contract address does not exist on specified chain — may return degraded result
- GoPlus or DexScreener data source unavailable — source_status will reflect degraded state
- Payment not attached or insufficient USDC — 402 Payment Required response
- Rate limiting or quota exceeded

## How this service works

Pay-per-call HTTP APIs, paid with x402 in USDC on Base (eip155:8453): agentkit, api-change-check, basedue, basewatch, chainread, check-sanctions, chgwatch, company-facts, composite, edgar, feednews, pageaudit, solcheck, token-dd, txpreflight, walletcheck, webmd, webread, websearch, x402index. Each operation describes its service.

## Output

Returns an object with ok status, a count of results, a per-token array (chain, address, token name/symbol, risk score 0-100, verdict such as lower_risk or moderate_risk, red flags list, source status from RPC/GoPlus/DexScreener, liquidity in USD), and a summary with verdict tallies, degraded count, and tokens ranked riskiest-first.
