[oSnipe](https://www.osnipe.app) is a Discord-based NFT alerting and autosniping tool created by [0xQuit](https://twitter.com/0xQuit). It monitors supported NFT marketplaces and chains, filters events against the rules you configure, and sends matching listings, sales, transfers, mints, and other activity to your private oSnipe channel. Subscriptions can be built from collection slugs, contract addresses, wallet addresses, traits, token IDs, price thresholds, floor percentages, best-offer percentages, rarity, marketplace filters, chain filters, and event-type filters. AutoSniper can then attach to eligible listing subscriptions so matching listings can be purchased automatically. Most setup and management can happen through Discord commands or the [oSnipe website](/osnipe/overview/website.md). Programmatic snipe triggers are covered in the [API section](/osnipe/api/api.md). All links related to the project can be found in [Official Links](/osnipe/official-links.md). ## Tiers Each Sniper's Pass and Purveyor's Pass holder gets a private Discord channel for their alerts. Sniper's Passes are the core access tier. Purveyor's Passes add higher limits and advanced routing features for users who run larger alert systems, communities, dashboards, or external workflows. Current listener limits enforced by the bot: * Snipers: up to 1,000 listeners across up to 100 collection slugs. * Purveyors: up to 10,000 listeners across up to 100 collection slugs, plus up to 100 offer-based listeners. Purveyors can route alerts to external Discord webhooks, X/Twitter destinations, and external trigger systems. Purveyors also get access to best-offer percentage filters and API credential management for programmatic sniping. Observer's Pass holders can be invited into a Sniper or Purveyor channel. Invites can be view-only, or the inviter can allow the Observer to manage commands on their behalf. ## Brief history {% embed url="" %} Explainer thread on the origin of oSnipe {% endembed %} If this tool and/or Quit has helped you and you want to give back, feel free to donate to `aveline.eth`.
