Endpoints and prices
| Method | Path | Description | Price | Network | Asset | 402 channel | Captured |
|---|---|---|---|---|---|---|---|
| GET | / | Everything in /bundle/market-brief (regime, sentiment, price, risk) plus an AI-generated synthesis connecting the signals and naming the single biggest risk factor · grounded only in the real data returned, never fabricated. For agents wanting one $2.50 call instead of a market brief plus a manual read. Input: ?symbol=SOL. Output: {symbol, regime, sentiment, price, risk, generated_at, disclaimer, analysis: {synthesis, key_risk}}. | $2.50 | Base | USDC | header | since 07-28 |
| GET | / | Complete market brief for one crypto asset in a single $1 call · trend regime, AI sentiment, live price with 24h/7d change, and volatility risk, combined from Stelar Digital's production classifiers. For agents needing full context before a trade decision without stitching together 4 separate calls. Input: ?symbol=SOL. Output: {symbol, regime, sentiment, price, risk, generated_at, disclaimer}. | $1.00 | Base | USDC | header | since 07-28 |
| GET | / | Grid-trading parameter recommendation for a crypto pair and capital amount · grid count, spacing percent, price band, and per-grid USD allocation, derived from live 24h market structure using the same spacing bounds as a production grid engine. For agents configuring, sizing, or backtesting a grid bot before deployment. | $0.05 | Base+ | USDC | header | since 07-28 |
| GET | / | Current price, 24h and 7d percent change, and a bullish/bearish/neutral signal for a crypto asset (SOL, BTC, ETH, XRP, DOGE, LTC, ADA, XLM). For agents needing a fast price-and-momentum check before a trade decision. Optional ?candles=N (up to 30, $0.05) adds N closed daily OHLC candles. | $0.005 | Base | USDC | header | since 07-28 |
| GET | / | Crypto market regime classification (choppy / uptrend / downtrend / high-volatility) for SOL, BTC, ETH, XRP, DOGE, LTC, ADA, or XLM, plus a grid-trading suitability verdict. Computed live from 1h klines, a 30-day volatility baseline, and EMA trend detection · the same classifier that steered our production grid bot before we retired it 2026-08-16. For agents deciding whether a pair is grid-tradeable right now. | $0.03 | Base+ | USDC | header | since 07-28 |
| GET | / | Volatility and drawdown risk regime for a crypto asset · current ATR percent versus its 30-day p80 baseline, labeled low/med/high, extending the same classifier behind /regime. For agents sizing positions or deciding whether to widen stops given current volatility. | $0.02 | Base | USDC | header | since 07-28 |
| GET | / | Sentiment score (-1 bearish to +1 bullish) and label for arbitrary text, or for a crypto asset based on its recent price action, via Claude Haiku. For agents gauging market mood or scoring news, social posts, or free text. | $0.005 | Base | USDC | header | since 07-28 |
| GET | / | Historical telemetry from our retired grid-trading bot - allocation, reconciled P&L, signal votes, and the human-approval trail for every trade. The bot stopped trading 2026-08-16; this endpoint serves its frozen record. | $0.005 | Base+ | USDC | header | since 07-28 |

How the score works
What the score read on this service: status online, 100% uptime 30d, 531ms response p95, x402 compliance 14 of 14, $0.005 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.
The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.
Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.
It is a score inside Data, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 381 listings, this one among them: the same 381 the position above is counted against. When the two differ, the field is the wider one, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.
Settled via coinbase ($0.75, 26 tx). Traction is a conservative undercount; first settlement seen 2026-07-02.

Live crypto grid-trading telemetry, market-regime classification, sentiment scoring, and price data from a real production trading operation. Built by one human + one AI.
Stelar Digital is a listed x402 Data API. Captured payment terms name Base, Solana. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.
Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.
