0x API

The 0x API v2 aggregates liquidity from on-chain DEXs and off-chain market makers across Ethereum and dozens of other EVM chains, returning the best executable price and a ready-to-sign transaction for a token swap. Two flavours are exposed: an Allowance Holder flow that uses a single approval contract, and a Permit2 flow that signs token allowances per trade. A separate Gasless endpoint set lets users trade without holding the native gas token by relaying signed messages. Designed for wallets, trading bots, and DeFi front ends that need consistent best-of-route pricing.

1Forge Finance APIs

Jentic maintains a curated, agent-optimized OpenAPI specification for 1Forge Finance APIs, validated against the live API and covering all five of its endpoints. It is not the only public specification: a third-party registry still serves a 2017 Swagger 2.0 copy of 1Forge's own document, though that copy reaches only the quote and symbol lookups and names a host 1Forge has since retired. 1Forge provides real-time forex and cryptocurrency market data through a small set of focused endpoints covering live quotes, currency conversion, supported symbol lists, and forex market status. Agents can pull bid/ask/mid prices for currency pairs such as EUR/USD or BTCUSD, convert specific amounts between currencies on demand, and check whether the forex market is currently open before placing logic. The API is designed for low-friction integration: a single API key authenticates all requests and responses are flat JSON objects.
