Co:Create

Co:Create (operated by Gesso Labs, Inc.) was an a16z crypto-backed web3 platform that gave brands and developers a REST API to build and run token-driven loyalty, rewards, and community programs on the Polygon blockchain. Its API-first toolkit let teams create and manage users and hosted wallets, deploy and manage ERC-20, ERC-721, ERC-1155, and Soulbound token contracts, mint and transfer tokens (with synchronous and asynchronous variants plus status polling), run reward Campaigns with built-in business logic, issue Referrals, and offer Redemptions, Auctions, and Prize Draws. It also provided NFT media/metadata hosting, fiat and crypto checkout (via a Crossmint integration), a Co:Create SDK, and Shopify/Salesforce integrations. The public developer surface (docs.usecocreate.io, api.cocrt.xyz) is now offline; this profile is reconstructed from the provider's own published documentation (archived) and preserved for the network.

Co:Create is listed with 1 API on the APIs.io network. Tagged areas include Company, Web3, Loyalty, Rewards, and NFT.

Co:Create’s developer surface includes documentation, API reference, getting-started guide, engineering blog, authentication, sandbox, and 7 more developer resources.

scored 2026-11-06 · rubric v0.27.0
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 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.
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/.

Agent readiness — checks not met, largest first (exact, from this profile):
  • Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
  • MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
  • Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
  • Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
  • Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
  • A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
12 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.
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 the provider profile at artifacts.apis.io/co-create/apis.yml: open an issue on github.com/api-evangelist/co-create to ask a question or point us at an artifact you publish.
