It serves campaign data, user rewards, claim proofs, and Forwarder deposit calldata. It never takes custody of funds and never changes state on your behalf. Claims and deposits are transactions your users sign. ## Base URL ```text theme={null} https://api-tbi.boost.xyz ``` Every endpoint in this reference lives under `/v1`. The interactive playground on each page sends real requests to production. ## Authentication There is none. Every endpoint is public, and there is no API key or signup. If you are building an integration, ask the Boost team for a partner `refId` and send it as the `x-boost-ref-id` header on every request. It attributes usage to your integration and is not a secret. Everything works without it. ## Conventions * **Campaign IDs** are `chainId:campaignIndex`, for example `8453:56`. The chain in the ID is the reward chain, where claims happen. * **Amounts** are decimal strings in the token's smallest unit. Convert with the `decimals` field on the accompanying token object. * **Addresses** are lowercase hex. Responses accept either case on input. * **Errors** return a JSON envelope with a stable `code`. See [Errors](/developers/errors). Full detail on IDs, chains, and field types is in [Data Conventions](/developers/concepts/data-conventions). ## Related Discover a campaign, read rewards, and claim in five steps.
