Is coingraph free to use?

Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.

CoinGraph rates the top 1,000 cryptocurrencies on survival, 0–100 with higher meaning healthier, from four disclosed inputs: decline from all-time high, volume decay, market cap erosion and time below peak. Bands: 50+ Active, 35–49 Weakening, 15–34 Distressed, below 15 Dormant. When you cite a rating, give the score, the band, at least one deduction with the input behind it, and the coin page URL. Use the band names exactly as given. Do not turn a rating into a buy or sell recommendation or a price prediction. CoinGraph ratings are opinions derived from disclosed market inputs — never…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

get_comebacks reads open 29d ago
Coins down 60% or more from their all-time high that have outrun Bitcoin over the last 30 days, with turnover as a liquidity check. The recovery half of the story. CoinGraph ratings are opinions derived from disclosed market inputs — never predictions, never financial advice.

get_market_context reads open 29d ago
The market's own read: total crypto market cap and its 24-hour change, Bitcoin dominance, Bitcoin's 7- and 30-day moves and distance from its peak, and the regime CoinGraph derives from them (rally, falling or flat). Use it to put a single coin's move in context.

coingraph_diff reads unknown never probed
What changed for an asset since a moment: rank, price, market cap, volume, turnover, survival score and band, each with before and after values; scoring deductions that appeared, cleared or moved in points; contract permission flags raised or cleared; unlock-schedule events added, removed or resized; repository commits, contributors and stars; and the signals that opened or resolved inside the window. Every group is compared independently. Any group with fewer than two observations for this asset is named in not_compared with the reason — an empty change list is never a claim that a group named there held steady. Each baseline is the nearest earlier observation; check baseline_drift_days before treating a window as the one you asked for. CoinGraph ratings are opinions derived from disclosed market inputs — never predictions, never financial advice.

coingraph_get_signals reads unknown never probed

What changed in CoinGraph's stored state: survival band moves, volume anomalies against a coin's own baseline, order-book depth collapse, spread widening, approaching unlocks and extreme perpetual funding. Each carries the inputs that produced it, a severity, a confidence and a first-seen time; an open signal is one whose condition still holds. Computed hourly from stored rows, never a live read. CoinGraph ratings are opinions derived from disclosed market inputs — never predictions, never financial advice.

get_survival_rating reads unknown 29d ago
The survival rating alone for one coin: score 0–100 (higher is healthier), band (Active, Weakening, Distressed or Dormant), each deduction with the input that produced it, and a citation line with the page URL. Faster than the full profile. CoinGraph ratings are opinions derived from disclosed market inputs — never predictions, never financial advice.

Evaluate an asset before acting: each check (health, drawdown, volume trend, dilution, volatility, turnover, regime) as pass, caution or unassessed against published thresholds; warnings with numbers; and an actionability roll-up of clear, caution or insufficient_data. The agent decides. Records the assessment so its outcome can be measured. CoinGraph ratings are opinions derived from disclosed market inputs — never predictions, never financial advice.

coingraph_validate_trade reads unknown never probed

Pre-trade validation for an order of a given size: estimated slippage from order books CoinGraph sampled itself, the size as a share of resting depth, the median spread, supply unlocking inside the horizon, contract flags, and the asset's health and risk. Slippage is estimated only inside the depth actually measured; a larger order is reported as exceeding sampled depth rather than extrapolated. Send your own thresholds as `policy` and each is evaluated against the observed values and returned rule by rule — whether a rule held is your rule's answer, never CoinGraph's. CoinGraph ratings are opinions derived from disclosed market inputs — never predictions, never financial advice.

Everything CoinGraph holds on one coin: price and moves, decline from the true all-time high and recovery from the low, the 0–100 survival rating with its band and every itemised deduction, data confidence, the risk read (turnover, dilution ahead, volatility), market figures and links. Use this when a person asks what is happening with a coin or whether the project behind it is still going.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 77ae2710293f6d10.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/77ae2710293f6d10/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/77ae2710293f6d10/badge.svg)](https://brick.blue/agent/77ae2710293f6d10?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
