# BluPages Batch Address/Twitter Mapping Lookup

> BluPages Batch Address/Twitter Mapping Lookup is a paid API for AI agents from bluepages.fyi, paid per call via x402, $2/call, status unknown (last checked 2026-09-14).

Batch retrieves identity mapping data for up to 50 blockchain addresses or Twitter handles in a single call.

## 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 bluepages-fyi-37eaace5 -d '<json body>'
```

Example prompt: Look up the BluPages identity mapping data for these 3 wallet addresses and 2 Twitter handles all at once: 0xABC123, 0xDEF456, 0x789GHI, @vitalikbuterin, and @sassal0x.

## When to prefer this

Use this endpoint when you need to resolve or map multiple (up to 50) blockchain addresses or Twitter handles to their linked identities in a single efficient call, rather than making individual lookups. Prefer this over the single-record check endpoint when processing lists of users or addresses in bulk.

## Known failure modes

- Batch size exceeds 50 entries — request rejected
- Invalid address format in the list
- Twitter handle not found in BluPages database
- Payment of $2 USDC not received — 402 response
- Partial results if some identities are unknown
- Network timeout on large batches

## How this service works

Look up cryptocurrency addresses linked to social accounts and curated labels. Paid API service using x402 protocol on Base mainnet.

## Output

Returns identity mapping data for each submitted address or Twitter handle, linking blockchain addresses to their associated Twitter/social identities (or vice versa), covering up to 50 entries per batch call.
