CurlShip

CurlShip (curlship.com) is a bot-friendly product directory built by indie developer Marcin Dudek that treats automated submissions as a feature: developers and AI agents can list a product with a single curl command against its REST API, through its MCP server, or via x402 USDC payment, with no account and no approval queue. Listings index OG tags automatically and are grouped by tier, from a free tier through paid plans starting at $1/month up to Platinum at $49/year and a bid-based Featured slot; the site publishes an OpenAPI reference, llms.txt, agents.md and agents.json for machine consumers.

CurlShip publishes 6 API contracts indexed on the APIs.io network, including Badge API, Billing API, Edits API, and 3 more. Tagged areas include Company, Directory, Product Listings, Developer Tools, and MCP.

The CurlShip catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

CurlShip’s developer surface includes changelog, authentication, API reference, documentation, pricing, support, and 33 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
