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.

The 1 Natural Way Public API provides access to reference data including insurance company listings, contact information submission, and US state codes for address validation. This API supports e-commerce checkout flows, prescription and supplement fulfillment systems, and health insurance integration workflows. Healthcare applications use it to validate insurance carriers for supplement benefit coverage, submit customer inquiries for follow-up, and ensure accurate address capture during order placement.

The 100Hires API connects to the 100Hires applicant tracking system, exposing endpoints to create candidate profiles, attach them to job openings or talent pools, and inspect the workflow stages defined in a hiring pipeline. It is a focused integration surface intended for syncing candidate data from external sources such as job boards, sourcing tools, and Zapier-style automations into a 100Hires workspace. Authentication is handled with an API key passed in the Authorization header, and all four endpoints exchange JSON payloads under the /zapier base path.
