Tristero

Tristero is a trustless, cross-chain trading protocol backed by General Catalyst. On-chain traders use its API and Python/TypeScript SDKs to access deep liquidity across DEXs and CEXs for spot swaps of ERC-20 tokens across EVM chains (via Permit2 / EIP-712 signed orders), leveraged margin positions up to 10x, and cross-VM swaps into non-EVM assets like Bitcoin, Monero, and Litecoin through its Feather balance-sheet swap relay. Execution is non-custodial and MEV-protected, with real-time quote streaming over WebSocket, and the company's research roots are in on-chain dark pools and encrypted order matching.

Tristero publishes 6 API contracts indexed on the APIs.io network, including Assets API, Orders API, Pricing API, and 3 more. Tagged areas include Company, Cryptocurrency, Trading, DeFi, and Cross-Chain.

The Tristero catalog on APIs.io includes 1 Spectral governance ruleset.

Tristero’s developer surface includes authentication, documentation, API reference, getting-started guide, engineering blog, support, sandbox, and 18 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime (on an ambiguous tag, where no other regime matched), 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/.

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.
