# GW8 Crypto Regime + WaveTrend Signal API — Per-Symbol Coin Data

> GW8 Crypto Regime + WaveTrend Signal API — Per-Symbol Coin Data is a paid API for AI agents from micro-saas-agent.onrender.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-22).

Returns WaveTrend oscillator values (wt1, wt2), band dots, and related market signal data for a given crypto symbol via a pay-per-call x402 micropayment endpoint.

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 gw8-crypto-regime-wavetrend-signal-api-per-symbol-coin-data-5a1e5a8a
```

Example prompt: What are the current WaveTrend wt1 and wt2 values for BTC right now — is it showing any overbought or oversold band dots?

## When to prefer this

Use this endpoint when you need WaveTrend oscillator readings (wt1/wt2) and band dot signals for a specific cryptocurrency symbol, particularly when operating within an x402 micropayment-capable agent pipeline. It is ideal for agents that need lightweight, per-call technical indicator data at $0.002 USDC without subscription overhead. Prefer this over broader market data APIs when the specific signal needed is WaveTrend momentum and regime context on a 4h Kraken feed.

## Known failure modes

- Invalid or unsupported symbol returns an error — only symbols available on Kraken are supported
- Payment not settled (x402 flow failure) — no charge on failure per provider policy
- Network timeout from Render.com cold-start latency
- Empty dots array if no recent band dots have occurred
- Symbol path parameter missing or malformed returns a routing error

## How this service works

Pay-per-call tools for AI agents via x402 (USDC on Base): should-I-pay decisions (spend policy + seller reputation in one call), spend-policy risk checks, x402 seller reputation verdicts, token safety verdicts, payment-rail cost checks, and crypto market data (regime, WaveTrend band dots, relative strength, flows, simulated hit-rate backtests). Agent guide: /agents.md. No charge on failure (settle only after data is ready), signed receipts, safe retries. Signal only, no trading, not financial advice.

## Output

A JSON object containing the coin name, current WaveTrend line values (wt1, wt2), previous WaveTrend values (prevWt1, prevWt2), and an array of recent band dot signals. These values reflect the LazyBear WaveTrend 10/21/4 oscillator on a 4-hour Kraken chart.
