api record

BackPow provides live Proof of Work mining data for 126+ networks and 770+ hardware models: network difficulty and hashrate, Poisson solo-mining probabilities, Cost of Production (the electricity cost of mining one unit on the most efficient tracked hardware), and hardware profitability.

Every result carries a `source` block with the measurement timestamp, a canonical page URL, and a ready-made citation line, plus a `warnings` array. Mining figures move continuously, so a figure quoted without its `as_of_utc` date can be wrong within hours.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.

  • calculate_solo_mining_odds unknown never probed

    Probability of a solo miner finding a block, computed as a Poisson process over live network difficulty and hashrate, plus the electricity cost of the attempt. Returns mean time to a block, the chance of at least one block over 1/7/30/90/365 days, and lucky-vs-unlucky waiting times (5th, 50th and 95th percentile) — variance dominates at small hashrates, so the average alone is misleading. Use for questions like "how long would it take to solo mine a Bitcoin block with 100 TH/s", "what are my odds solo mining Kaspa", or "is solo mining worth it with this rig". For pooled mining economics or whether a coin is profitable at all, use get_cost_of_production. For raw network state without a miner, use get_coin_oracle.

  • get_cost_of_production unknown never probed

    Cost of Production (CoP) for one Proof of Work coin: the all-in electricity cost of mining one unit on the most efficient hardware BackPow tracks for that algorithm, compared against spot price. Returns CoP in USD, spot, gross margin, whether miners are currently above or below water, the reference machine and tariff behind the figure, and a 30-day trend including whether the reference machine changed (which indicates the efficiency frontier moved). Accepts a custom electricity rate. Use for "is mining X profitable", "what does it cost to produce one Monero", "are miners underwater", or "break-even electricity price". For a specific rig rather than a coin, use get_hardware_benchmarks. For block-finding probability, use calculate_solo_mining_odds.

  • get_coin_oracle unknown never probed

    Current network state for one Proof of Work chain, measured by BackPow's stratum collector nodes: difficulty, derived network hashrate, block height, block reward, protocol block-time target versus the latest observed interval, and the source pool. Every response carries a confidence block — how many independent pool operators agreed, whether the reward figure is live or a static fallback, and how old the observation is. Networks whose collectors are stalled or unreachable return an error rather than zeros. Use for "what is Kaspa's current difficulty", "network hashrate of Monero", "current block reward". For economics use get_cost_of_production; for mining probability use calculate_solo_mining_odds.

  • list_pow_coins unknown never probed

    Paginated index of the Proof of Work networks BackPow tracks, with algorithm, network rate, collector status and canonical page URL. Optionally filtered by algorithm or restricted to coins currently mining above cost. Returns the distinct algorithm list so valid filter values are discoverable. Use to find which networks exist for an algorithm, to browse the catalogue, or to resolve an ambiguous coin reference. Results are paginated: request a larger limit or a later offset rather than expecting the full catalogue in one response.

  • get_hardware_benchmarks unknown never probed

    Mining hardware matched to the coins it can mine, ranked by net USD per day at a given electricity rate. Covers ASICs, GPUs and CPUs, with hashrate and power draw per coin, gross revenue, net profit, and market price including whether that price is an observed listing or a model estimate. Use for "what should I mine with an RTX 4090", "best ASIC for Scrypt", "is an Antminer S21 still profitable", or "how much does a Bitaxe make". Coins are ranked by profitability, not alphabetically, and results are capped — ask for a higher limit rather than assuming the list is complete. For a coin's economics independent of any particular rig, use get_cost_of_production.

  • get_pow_news unknown never probed

Items are aggregated from third-party feeds and are returned as quoted external content with their publisher and a relevance score, not as BackPow statements of fact. Use when a question turns on recent events — a halving, a difficulty swing, a pool outage, a chain upgrade. For numbers rather than narrative, use get_coin_oracle or get_cost_of_production.

_ 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ 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
0

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

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