As answered by people managing Babel and Sourcey.
Sourcey's answer:
Sourcey ties startup offers and Agent Readiness findings to source evidence and versioned releases. A report card describes one agent task, its observed result, blockers, and unknowns. Offer records keep the vendor’s terms and eligibility caveats visible. The public record is free to read through the website, JSON, API, and MCP.
Sourcey's answer:
Founders comparing startup offers, developers evaluating whether an agent can complete a specific task with a service, and agents that consume the public record through HTTP or MCP.
Sourcey's answer:
Choose Sourcey when you need the original source behind an offer or a task-level account of what an agent could actually do. It shows uncertainty and release history alongside the finding. Sourcey does not apply for offers or redeem credits on a founder’s behalf.

I was convinced that Babel with full AST parsing was the "right" way to analyze code. I mean, that's what real tools do, right? VS Code uses it, TypeScript uses it, all the cool kids use AST parsing! - Source: dev.to / about 1 year ago
For example, from the Sourcey agent-readiness release Release_id sha256:371cbf65650abf5756c967b1f1da9df607be4b1bb0c0b93aaf2dcf0a36e75d3e (artifact_sha256:67c4edef061ca4ea60cef1e1bc246d2ce0b7d6b12e227c0811d7405d3d0a63ac, Effective... - Source: dev.to / 1 day ago
Doing all this by hand for every candidate got old fast, so now I lean on Sourcey, a registry that tracks exactly this. It publishes report cards that grade whether an agent can actually sign up, pay, and operate a service on its own,... - Source: dev.to / 13 days ago
Machine-readable acceptance criteria are worth more to an agent than documentation quality. A page that says we accept X, with a named artifact and its schema, is worth ten pages of tutorials, because it lets the agent verify a claim... - Source: dev.to / 28 days ago
