Deriv contracts_for
Lists the contracts that can be bought on one symbol now, with the barrier, stake and duration limits of each. On a logged in connection only the contracts that account may trade are returned.
Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

}Limits that apply at Deriv
| Limit | Value | Scope | Source |
|---|---|---|---|
| Headline limit | 80/min per logged in user (REST)Sources conflict developers.deriv.com states 60, checked . Deriv's API overview in the text form it publishes for AI tools gives REST 60 requests a minute per token, where its Limits page gives 80 a minute per logged in user. The same overview also gives 100 WebSocket requests a second per connection, 100 active subscriptions per connection and 5 concurrent WebSocket connections per user, none of which the Limits page mentions. Deriv's own pages disagree; the conflict is labelled, not resolved. Pace against 60. | user, REST | developers.deriv.comchecked |
