The D-Central Mining API is a free, keyless, read-only REST API for Bitcoin ASIC mining data. Six endpoints serve JSON over HTTPS: live Bitcoin hashprice, the full ASIC miner spec database, bench-validated power/tuning profiles, the 650-code error-code corpus, the reliability & failure-mode index, and a live Canadian-dollar price index. No account, no key, no rate-limit paperwork — just send a GET request.
Everything is released under a Creative Commons Attribution 4.0 licence. Use it in your own tools, dashboards, research or AI systems; the only ask is that you credit D-Central and link back. The same data is also available as static CSV/JSON downloads on the Open Data Hub.
Quick answer
The D-Central Mining API is a free, keyless, read-only REST API at https://d-central.tech/wp-json/dc/v1. It serves six datasets as JSON — live Bitcoin hashprice, the ASIC miner spec database, power/tuning profiles, the error-code corpus, the reliability/failure-mode index, and a live CAD price index — all under a CC BY 4.0 licence. No sign-up, no API key: just GET the endpoint.
Free and keyless. Cache responses, attribute D-Central, and you are good to go.

Method: GET · Auth: none ·
Format: JSON · CORS: open (*) ·
Licence: CC BY 4.0.
Please be a good citizen: cache responses (every endpoint sends a
Cache-Control header), keep it under roughly 60 requests per minute, and for bulk
or repeated access pull the static CSV/JSON exports
instead of hammering the API. Each response carries an X-DC-API courtesy notice. There are no hard
limits today — abuse just gets rate-limited at the edge.
/dc/v1/hashpriceLive Bitcoin hashprice — expected mining revenue per unit of hashrate per day, in USD and CAD, per TH/day and per PH/day, subsidy-only and fee-inclusive. Refreshed every 15 minutes. Includes network difficulty, BTC price, block subsidy, fee revenue and halving/retarget context.
No parameters.
Example
curl https://d-central.tech/wp-json/dc/v1/hashprice/dc/v1/minersThe full ASIC miner spec database — hashrate, power, J/TH efficiency, algorithm, manufacturer, status, BTU, home-mining score and the live linked product (CAD price + stock) for each model.
Parameters
algorithm — filter by algorithm slug (e.g. sha-256)manufacturer — filter by manufacturer slug (e.g. bitmain)Example
curl https://d-central.tech/wp-json/dc/v1/miners?manufacturer=bitmain/dc/v1/power-profilesBench-validated power/tuning points (wattage, hashrate, J/TH) for each undervolt/overclock step across the supported models. Per-domain voltage; firmware autotuners calculate at runtime — these are not fixed presets.
Parameters
model — filter to one model slug (e.g. antminer-s19j-pro)Example
curl https://d-central.tech/wp-json/dc/v1/power-profiles?model=antminer-s19j-pro/dc/v1/error-codesThe ASIC error-code corpus — fault code, severity, DIY difficulty, CAD repair-cost band and the exact replacement-part SKUs that fix it, with the link to each repair guide. Paginated.
Parameters
manufacturer — filter by manufacturer (substring, e.g. Bitmain)component — filter by failing component (e.g. hashboard, psu, fan)code — filter by error code (substring)search — free-text search over code, title and affected modelspage — page number (default 1)per_page — rows per page (default 100, max 500)Example
curl https://d-central.tech/wp-json/dc/v1/error-codes?manufacturer=Bitmain&component=hashboard&per_page=25/dc/v1/reliabilityThe ASIC reliability & failure-mode index — per-model failing-component breakdowns with reported-frequency qualifiers and A/B/C source-strength grades. Aggregated from public sources; not internal repair-ticket counts or measured failure rates.
Parameters
model — filter to one model (slug or model name slug, e.g. antminer-s19-pro)Example
curl https://d-central.tech/wp-json/dc/v1/reliability?model=antminer-s19-pro/dc/v1/price-indexD-Central's own live catalogue CAD price index for ASIC miners — name, SKU, condition (new vs refurbished), live price, stock status and a min/median/max summary. A single-vendor reference, not a market-wide aggregate.
Parameters
condition — new | refurbishedcategory — filter by product category slug (asic-miners, bitaxe, quiet-modded-antminers)Example
curl https://d-central.tech/wp-json/dc/v1/price-index?condition=refurbishedAll data is released under Creative Commons Attribution 4.0.
