## 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 x402-twitter-profile-id-lookup-f7bb9b26
```

Example prompt: What's the Twitter user ID for the account with the handle 'elonmusk'? Use the x402 micropayment API mirror — no API key needed, just pay the $0.05 USDC fee.

## When to prefer this

Choose this endpoint when you need to resolve a Twitter/X username to a numeric user ID without holding Twitter API credentials. Ideal for agents that need programmatic access to Twitter identity data using x402 USDC micropayments on Base, avoiding OAuth setup entirely.

## Known failure modes

- Username not found — returns non-zero code with empty data
- Invalid or malformed username in path parameter — may return error code
- Payment failure via x402 micropayment — 402 response if USDC payment not processed
- Rate limiting or upstream X/Twitter API unavailability — service may return error
- URL template not resolved correctly (literal {name} in path) — returns 404

## How this service works

ReadX is a read-only X/Twitter JSON API. Profiles, timelines, tweets, search & lists — pay per call with x402 micropayments in USDC on Base or Solana. No API keys.

## Output

Returns a JSON object with a code field (0 for success) and a data object containing the resolved Twitter/X user ID and associated profile metadata for the requested username.
