Forta

Forta is a decentralized, real-time detection network for monitoring the security and operational health of Web3 systems. Spun out of OpenZeppelin and backed by a16z crypto, Forta runs thousands of community-built detection bots across independent scan nodes that inspect every transaction and block on chains such as Ethereum, Polygon, BNB Chain, Avalanche, Arbitrum and Optimism, emitting alerts that DeFi protocols and security teams subscribe to via email, Slack, Telegram, Discord and webhooks. Developers query alerts and threat intelligence through a GraphQL API, build and deploy detection bots with the Forta Bot SDK and CLI (JavaScript/TypeScript and Python), and the Forta Firewall product uses the Forta Chain (a Layer 3 network) to block smart-contract exploits before they execute.

Forta publishes 1 API on the APIs.io network. Tagged areas include Company, Security, Blockchain, Web3, and Monitoring.

The Forta catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Forta’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, signup flow, authentication, and 16 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/forta: open an issue to ask a question, or submit a pull request to add artifacts.
