Gridcoinstats API

read-only

Public, read-only statistics of the Gridcoin chain, from the cache database of Gridcoinstats. It never calls the wallet, so it keeps answering when the wallet is down. For live wallet data there is the wallet API (/wallet/v3). Answers are JSON:API documents (application/vnd.api+json). Amounts are decimal strings with 8 decimals (GRC); times are Unix seconds with an _iso twin (UTC); a value the cache does not have is null, never 0. The API has feeds and snapshots, with a hard cap: there is no lookup of a single older block or transaction by id, and no paged list of a whole table. The path's v4 is the generation of the cache database it is built for.

It is for what a page needs to follow the chain as it moves, and for sites that list coins: a live feed of the newest blocks and transactions, the pool, the network figures, the coin supply and how current the data is. For what only the wallet knows there is the wallet API.

Description for tools
curl -s https://api.gridcoinstats.eu/gridcoinstats/v4/mainnet/status

Conventions

Answers are JSON:API documents (application/vnd.api+json). Every answer has jsonapi.version, data, links.self and meta.network (null for the BOINC status) and meta.version; a feed also has meta.indexedHeight, the newest block the figures are from.

Amounts are decimal strings with 8 decimals in GRC ("515348757.64213040"), built from the base units without a float. Times are Unix seconds with an _iso twin in UTC (2026-10-13T07:49:04Z). A value the cache does not have is null, never 0.

Feeds have a hard cap. The blocks, the transactions and the pool give the newest page[size] items (default 25, at most 100) and nothing else: another page, a sort order or a filter the endpoint does not take is a 400, so a client cannot walk the chain through the API.

Caching. Every read sends Cache-Control: public, max-age=N, stale-while-revalidate=M and an ETag; ask again with If-None-Match and an unchanged answer is a 304. Cloudflare keeps the answers for their max-age, which each endpoint below states.

Read only, open to any site. GET, HEAD and OPTIONS are answered; any other method is a 405. CORS is open (Access-Control-Allow-Origin: *), so a page on another site can read it.

Errors and limits

An error is a JSON:API document with an errors list: status, title, detail, and for a wrong query parameter code and source.parameter.

The statuses an error can have
StatusWhen
400A parameter the endpoint does not take, or a value out of range or of the wrong kind (`page[number]=2` on a feed, `filter[kind]=x`).
405Any method but GET, HEAD and OPTIONS: the API only reads. `Allow: GET, HEAD, OPTIONS`.
429More than 60 requests a minute from one IP (`Retry-After` says how long to wait).
503The cache database cannot be read (the details are in the log, not in the answer), or it is not a v4 database.

The limit is 60 requests a minute from one IP address, all endpoints together; the answers carry X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset, and a 429 has Retry-After. Only the requests that reach our server count: Cloudflare keeps an answer for its max-age. Poll no faster than the max-age of the endpoint.

Description

GET /gridcoinstats/v4
