# RobinX Token Feature Row

> RobinX Token Feature Row is a paid API for AI agents from api.robinx.io, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

Returns a comprehensive token-level feature row for a Robinhood Chain token, including launch facts, current price/activity/deployer/caller state, and mention history — raw inputs for custom models, no score or recommendation included.

## Facts

- Endpoint: GET https://api.robinx.io/agent/features

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 robinx-token-feature-row-7477a0b1
```

Example prompt: Pull the full RobinX feature row for token 0x020bfC650A365f8BB26819deAAbF3E21291018b4 on Robinhood Chain — I need the launch identity, current price, swap activity, deployer record, caller state, and mention history to feed into my own scoring model.

## When to prefer this

Choose this endpoint when you need raw, structured feature data for a specific Robinhood Chain (chain 4663) token to feed into your own model or scoring pipeline — not when you want a pre-computed score or recommendation. It is the right choice when you need a single authoritative snapshot combining launch identity, on-chain activity, social mentions, deployer history, and caller quality signals in one call. Prefer it over sibling endpoints when you need the broadest feature coverage for a single token rather than a caller's call log or a deployer-only grade.

## Known failure modes

- Token address not found on Robinhood Chain (chain 4663) — known:false returned with empty coverage
- Token exists but some feature families unavailable (e.g. structure.available:false, caller_state.available:false)
- Price data stale — stale:true flag set with elevated px_age_hours
- Mention data unavailable for very new tokens not yet observed by RobinX
- Payment failure via x402 protocol — endpoint returns 402 if USDC payment not included
- Invalid or malformed token address returns error response

## How this service works

Token-level feature row for one Robinhood Chain token: launch facts, current activity/deployer/price/caller state, and the observed mention record — inputs for your own model (no score, no recommendation)

## Output

A JSON object containing a single token's full feature row: identity fields (name, symbol, deployer address, age in hours, launch block, first observed timestamp), current price state (FDV in WETH, last price in WETH, price age, staleness flag), activity metrics (swap count, trader count, WETH volume, is_real flag), deployer record (score, launch count, dead/real counts), caller state (graded account count, measured callers, best early rate, cluster share of graded), and mention data (total mentions, last 24h count, distinct accounts in sample, first tweet/capture timestamps). No score or recommendation is included — only raw inputs for downstream models.
