API

caution

Our API is still in alpha — things may change or break at any time!

If you have questions, come chat with us on Discord. We’d love to hear about what you build!

General notes​

Some APIs are not associated with any particular user. Other APIs require authentication.

APIs that require authentication accept an Authorization header in one of two formats:

  • Authorization: Key {key}. A Manifold API key associated with a user account. Each account may have zero or one API keys. To generate an API key for your account, visit your user profile, click "edit", and click the "refresh" button next to the API key field at the bottom. You can click it again any time to invalidate your existing key and generate a new one.

  • Authorization: Bearer {jwt}. A signed JWT from Firebase asserting your identity. This is what our web client uses. It will probably be annoying for you to generate and we will not document it further here.

API requests that accept parameters should either have the parameters in the query string if they are GET requests, or have a body with a JSON object with one property per parameter if they are POST requests.

API responses should always either have a body with a JSON result object (if the response was a 200) or with a JSON object representing an error (if the response was a 4xx or 5xx.)

Endpoints​

GET /v0/user/[username]​

Gets a user by their username. Remember that usernames may change.

Requires no authorization.

GET /v0/user/by-id/[id]​

Gets a user by their unique ID. Many other API endpoints return this as the userId.

Requires no authorization.

GET /v0/me​

Returns the authenticated user.

GET /v0/groups​

Gets all groups, in no particular order.

Requires no authorization.

GET /v0/groups/[slug]​

Gets a group by its slug.

Requires no authorization.

GET /v0/groups/by-id/[id]​

Gets a group by its unique ID.

Requires no authorization.

GET /v0/markets​

Lists all markets, ordered by creation date descending.

Parameters:

  • limit: Optional. How many markets to return. The maximum and the default is 1000.
  • before: Optional. The ID of the market before which the list will start. For example, if you ask for the most recent 10 markets, and then perform a second query for 10 more markets with before=[the id of the 10th market], you will get markets 11 through 20.

Requires no authorization.

POST /v0/bet​

Places a new bet on behalf of the authorized user.

Parameters:

  • amount: Required. The amount to bet, in M$, before fees.
  • contractId: Required. The ID of the contract (market) to bet on.
  • outcome: Required. The outcome to bet on. For binary markets, this is YES or NO. For free response markets, this is the ID of the free response answer. For numeric markets, this is a string representing the target bucket, and an additional value parameter is required which is a number representing the target value. (Bet on numeric markets at your own peril.)
  • limitProb: Optional. A number between 0.001 and 0.999 inclusive representing the limit probability for your bet (i.e. 0.1% to 99.9% — multiply by 100 for the probability percentage). The bet will execute immediately in the direction of outcome, but not beyond this specified limit. If not all the bet is filled, the bet will remain as an open offer that can later be matched against an opposite direction bet.
    • For example, if the current market probability is 50%:
      • A M$10 bet on YES with limitProb=0.4 would not be filled until the market probability moves down to 40% and someone bets M$15 of NO to match your bet odds.
      • A M$100 bet on YES with limitProb=0.6 would fill partially or completely depending on current unfilled limit bets and the AMM's liquidity. Any remaining portion of the bet not filled would remain to be matched against in the future.
    • An unfilled limit order bet can be cancelled using the cancel API.

Example request:

$ curl https://manifold.markets/api/v0/bet -X POST -H 'Content-Type: application/json' \
-H 'Authorization: Key {...}' \
--data-raw '{"amount":1, \
"outcome":"YES", \
"contractId":"{...}"}'

POST /v0/bet/cancel/[id]​

Cancel the limit order of a bet with the specified id. If the bet was unfilled, it will be cancelled so that no other bets will match with it. This is action irreversable.

POST /v0/market​

Creates a new market on behalf of the authorized user.

Parameters:

  • outcomeType: Required. One of BINARY, FREE_RESPONSE, or NUMERIC.
  • question: Required. The headline question for the market.
  • description: Required. A long description describing the rules for the market.
    • Note: string descriptions do not turn into links, mentions, formatted text. Instead, rich text descriptions must be in TipTap json.
  • closeTime: Required. The time at which the market will close, represented as milliseconds since the epoch.
  • tags: Optional. An array of string tags for the market.

For binary markets, you must also provide:

  • initialProb: An initial probability for the market, between 1 and 99.

For numeric markets, you must also provide:

  • min: The minimum value that the market may resolve to.
  • max: The maximum value that the market may resolve to.

Example request:

$ curl https://manifold.markets/api/v0/market -X POST -H 'Content-Type: application/json' \
-H 'Authorization: Key {...}'
--data-raw '{"outcomeType":"BINARY", \
"question":"Is there life on Mars?", \
"description":"I'm not going to type some long ass example description.", \
"closeTime":1700000000000, \
"initialProb":25}'

POST /v0/market/[marketId]/resolve​

Resolves a market on behalf of the authorized user.

Parameters:

For binary markets:

  • outcome: Required. One of YES, NO, MKT, or CANCEL.
  • probabilityInt: Optional. The probability to use for MKT resolution.

For free response markets:

  • outcome: Required. One of MKT, CANCEL, or a number indicating the answer index.
  • resolutions: An array of { answer, pct } objects to use as the weights for resolving in favor of multiple free response options. Can only be set with MKT outcome.

For numeric markets:

  • outcome: Required. One of CANCEL, or a number indicating the selected numeric bucket ID.
  • value: The value that the market may resolves to.

Example request:

# Resolve a binary market
$ curl https://manifold.markets/api/v0/market/{marketId}/resolve -X POST \
-H 'Content-Type: application/json' \
-H 'Authorization: Key {...}' \
