# Web3 Signals API – Full Crypto Signal Fusion

> Web3 Signals API – Full Crypto Signal Fusion is a paid API for AI agents from web3-signals-api-production.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-18).

Returns composite 0-100 conviction scores across 6 dimensions (whale, derivatives, technical, narrative, market, trend) for 20 crypto assets, plus portfolio summary and LLM-generated insights

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 web3-signals-api-full-crypto-signal-fusion-fbdf5041
```

Example prompt: Give me the full crypto signal report right now — composite conviction scores, whale and derivatives data, and the AI market summary across all 20 assets so I can see which ones are rated BUY and what the current market regime is.

## When to prefer this

Use this endpoint when you need a multi-dimensional, AI-fused crypto signal covering whale on-chain flows, derivatives positioning, technical indicators, and social narrative all in a single call for 20 assets at once. Prefer this over single-indicator or single-asset endpoints when you want a holistic portfolio-level view with natural language LLM commentary.

## Known failure modes

- Payment not included or invalid x402 payment header — returns 402 Payment Required
- Upstream data source unavailable — may return partial signals or 503
- Rate limiting if called too frequently — returns 429
- Network timeout on Railway deployment — returns 504

## How this service works

Live buy/sell signals for 20 crypto majors (BTC, ETH, SOL, ...): each asset scored 0-100 from 6 fused dimensions — whale flows, technicals, derivatives, narrative, market regime, trend — with direction, conviction, entry/target/stop levels, and LLM insight. Refreshed every 15 min. Verify accuracy first, free: /performance/reputation (confidence-gated, no inflated claims).

## Output

A JSON object keyed by ticker (BTC, ETH, SOL, etc.) containing per-asset objects with: composite_score (0-100 integer; >62 = bullish, <38 = bearish), label (BUY/SELL/HOLD/ABSTAIN), direction, conviction (high/medium/low), six dimension sub-scores (whale, derivatives, technical, narrative, market, trend), llm_insight string, predicted_move with 24h/48h probabilities, and signal_strength. Plus a portfolio_summary with market regime (TRENDING/RANGING/VOLATILE), overall risk level, and top buy/sell picks.
