Routes

Method	Path	Returns
GET	`/overview`	Market-wide summary
GET	`/tokens`	The token index: the stamp index merged with the StampDEX order book
GET	`/tokens/priced`	A faster feed of tokens with live exchange prices
GET	`/tokens/:tick`	One token in detail
GET	`/tokens/:tick/context`	Token context including the order book
GET	`/tokens/:tick/prices`	Recorded price history
GET	`/tokens/:tick/trades`	Recent trades
GET	`/tokens/:tick/activity`	Per-token activity
POST	`/tokens/prices`	Prices for a list of tickers in one call
GET	`/deployments/:tick`	Every deployment claiming a ticker
GET	`/deployments/tx/:deployTx`	The deployment behind a transaction
GET	`/fees`	Recommended Bitcoin fee rates

Parameters

Parameter	Where	Range
`page`	`/tokens`, `/tokens/priced`, `/tokens/:tick/activity`	1 upwards
`limit`	`/tokens`	Up to 500. 0 means every row
`limit`	`/tokens/priced`	Up to 500
`limit`	`/tokens/:tick/prices`	Up to 500, default 200
`limit`	`/tokens/:tick/trades`	Default 50

Tickers are uppercase. The API upcases what you send. An unknown ticker returns an empty result, not an error.

Example

curl "https://stamp.api.bitcoinuniverse.io/api/v1/market/tokens/KEVIN"

Reading the numbers

Every row carries a sources object naming the origin of each figure: stampchain, stampdex, or none. See Data provenance.
Every row carries deploy_tx, deploy_block, deploy_time, and creator. sources.identity reads stampchain when a source reported one and none when none did. deploy_tx is null in that case, and the ticker is never used in its place.
mint_progress is minted supply against max supply, as a percentage.
total_minted and max_supply are strings, so a very large supply does not lose precision.
A null or absent value means the source had no answer. It is never replaced with 0.
A market cap above 21,000,000 BTC is reported as unknown rather than repeated.
Listing prices come from real signed listings. A stored listing whose unit price contradicts its total is left off the book rather than shown at a wrong price.

Deployment resolution

curl "https://stamp.api.bitcoinuniverse.io/api/v1/market/deployments/KEVIN"

The response carries resolution with one of single, ambiguous, unknown, or unavailable, plus source, source_available, observed_at, and a deployments array. Each entry names tick, deploy_tx, deploy_block, deploy_time, creator, max_supply, and mint_limit.

Going the other way:

curl "https://stamp.api.bitcoinuniverse.io/api/v1/market/deployments/tx/23765f9bc6b87e078b1f93ed213f90b9004998336575f726e46f34ddbea5e5f3"

That returns found and the deployment. A value that is not 64 hex characters returns HTTP 400 rather than being searched for.

Fee rates

curl "https://stamp.api.bitcoinuniverse.io/api/v1/market/fees"

Five tiers: fastest, half hour, hour, economy, and minimum. If any tier is missing or is not a number, the whole response is rejected with HTTP 502. Partial fee data is never served. See Fees.

Common failures

Status	Meaning
400	A malformed parameter, such as a transaction id that is not 64 hex characters
429	Over the rate limit. See Rate limits
502	The upstream node returned fee estimates that did not validate
