Access real-time X/Twitter attention intelligence for Base chain tokens via the checkr API. Use when you need to know what is trending on CT, which tokens are spiking in social attention, get attention/price divergence signals, or fetch narrative summaries for specific Base tokens. Triggers: "what's trending on Base", "check attention for $TOKEN", "what's spiking right now", "social signal for X", any token research needing CT attention data. Payments via x402 — USDC on Base, no API key or account needed.

What this skill does


# checkr

Real-time X/Twitter attention intelligence for Base chain tokens.

**Base URL:** `https://api.checkr.social`  
**Docs:** `https://api.checkr.social/docs`  
**Payment:** x402 — USDC on Base mainnet, pay-per-call, no account needed.

## Endpoints

| Endpoint | Price | What it returns |
|---|---|---|
| `GET /v1/leaderboard` | $0.02 | Top Base tokens ranked by social attention share |
| `GET /v1/spikes` | $0.05 | Tokens currently velocity-spiking (the radar sweep) |
| `GET /v1/token/{symbol}` | $0.50 | Deep dive: ATT deltas, price, divergence, narrative |
| `GET /v1/bankr` | $0.02 | Attention leaderboard for the bankr agent ecosystem |

Full response schemas and field definitions: `https://api.checkr.social/docs`

## How to Call (x402)

x402 is pay-per-call. No API key or account. Wallet + USDC on Base is all you need.

**Python:**
```python
from x402.client import x402_client

client = x402_client(wallet=YOUR_WALLET)

# What's spiking right now — $0.05
spikes = client.get("https://api.checkr.social/v1/spikes").json()

# Top tokens by attention — $0.02
leaderboard = client.get("https://api.checkr.social/v1/leaderboard").json()

# Deep dive on a token — $0.50
token = client.get("https://api.checkr.social/v1/token/BNKR").json()
```

**TypeScript:**
```typescript
import { withPaymentInterceptor } from "x402-axios";
import axios from "axios";

const client = withPaymentInterceptor(axios.create(), walletClient);

const { data } = await client.get("https://api.checkr.social/v1/spikes");
```

Payment is handled automatically by the x402 client — it intercepts the 402, signs and sends payment, then retries with the receipt.

## Practical Flow

Use spikes as your radar. Drill into token for context.

```python
# 1. What's moving?
spikes = client.get("https://api.checkr.social/v1/spikes").json()
# → [{ symbol: "TIBBIR", velocity: 3.9, ATT_pct: 11.4, divergence: false, hawkes: {...} }]

# 2. Deep dive on the top spike
top = spikes["spikes"][0]["symbol"]
detail = client.get(f"https://api.checkr.social/v1/token/{top}").json()
# → full price, divergence, spike history, narrative
```

## Key Fields

**On every response:**
- `data_age_minutes` — how fresh the data is. Use before acting.

**On spikes:**
- `velocity` — momentum multiplier vs baseline. 3.0+ = meaningful spike.
- `divergence` — `true` = attention up, price flat/down. The alpha pattern.
- `hawkes.viral_class` — `BUILDING` / `SUSTAINED` / `FADING`. Is this self-reinforcing?
- `rotating_from` — tokens losing attention as this one gains.
- `narrative_summary` — AI-generated 180-char brief. `null` if signal below confidence threshold.

**On token deep dive:**
- `ATT_delta_1h` / `ATT_delta_4h` — attention share movement over time.
- `spike_history.hit_rate` — % of past spikes with confirmed price follow-through.
- `narrative.type` — `infrastructure` / `ecosystem` / `fud_defense` / `meme` / `launch_hype`.

## Query Params

```
GET /v1/leaderboard?limit=10&sort_by=ATT_pct&min_mentions=5
GET /v1/spikes?min_velocity=3.0&min_mentions=10&divergence_only=false
```

## Requirements

- USDC on Base mainnet
- Python: `pip install x402`
- TypeScript: `npm install x402-axios`
- Base gas for payment (~$0.01)

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
