Ajaib

Ajaib is an Indonesian fintech and online brokerage founded in 2018 that gives retail investors access to Indonesian stocks, mutual funds, bonds, US stocks and crypto from a single mobile app. It operates PT Ajaib Sekuritas Asia for equities and Ajaib Kripto for digital assets, and became Southeast Asia's first investment unicorn in 2021. Its one public developer surface is the Ajaib Coin Exchange API, a REST trading interface for the crypto venue, documented on GitBook and organized into Market Info, Wallet and Spot Trading. Access is not self-service: clients generate an ECDSASHA256 keypair, email the public key to Ajaib, and sign every request with X-API-KEY, X-SIGNATURE and X-TIMESTAMP headers. Ajaib publishes no OpenAPI, no SDKs and no status page.

Ajaib publishes 3 APIs on the APIs.io network: Market Info API, Spot Trading API, and Wallet API. Tagged areas include Company, Financial-Services, Investing, Brokerage, and Trading.

Ajaib’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, authentication, sandbox, and 21 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ajaib: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →

  detail: Ajaib's public developer surface is the Ajaib Coin Exchange API, fully documented on GitBook with a verbatim llms.txt;
    the API hosts themselves (api.ajaib.co.id, api.ajaib.tech) return a Cloudflare 403 bot challenge on every path, so no
    live spec probe or well-known read was possible there.
