M 0

M0 (M0 Foundation) is modular stablecoin infrastructure that lets organizations launch and operate a custom, brand-owned stablecoin across EVM chains and Solana. Its platform splits into configurable application, distribution, and issuance layers, and exposes two developer APIs: the Orchestration REST API for quoting and executing cross-chain stablecoin conversions between M0 extensions and stablecoins like USDC and USDT, and the Protocol GraphQL API for querying on-chain supply, holder balances, yields, and configuration. Backed by Earlybird and other crypto investors; used by MetaMask, PayPal, and MoonPay.

M 0 publishes 4 APIs on the APIs.io network, including Order API, Permit API, Quote API, and 1 more. Tagged areas include Company, Stablecoins, Cryptocurrency, Blockchain, and Payments.

M 0’s developer surface includes authentication, sandbox, changelog, documentation, API reference, engineering blog, support, and 17 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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.
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/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/m-0: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
