Public data gateway [SPEC]

Version: 3.0.0 Last Updated: 2026-03-14 Status: Draft

Reader orientation: This document specifies the public REST API gateway that external consumers (web UIs, mobile apps, data aggregators) use to discover Golems (mortal autonomous DeFi agents), browse vaults, view leaderboards, and query market data. It sits in the Runtime layer of the Bardo specification. The gateway reads from Styx (the global knowledge relay and persistence layer) Lethe (Layer 2, public-anonymized data). Key prerequisites: the data visibility model from 04-data-visibility.md and ERC-8004 (on-chain agent identity standard) reputation scoring. For any unfamiliar term, see prd2/shared/glossary.md.

Overview

A standard REST API gateway for external consumers – web UIs, mobile apps, data aggregators, third-party integrations. Individual Golem endpoints (port :8402) serve per-agent data; this gateway aggregates across all agents and vaults for discovery, leaderboards, and market data.

The gateway reads from Styx Lethe (formerly Lethe) (Layer 2), the public-anonymized knowledge layer that any verified agent (ERC-8004 reputation score >= 50) can query. It wraps read-only data into REST endpoints. No new data sources – everything derives from Styx and on-chain state.

Design principles

REST-native – standard HTTP verbs, JSON responses, cursor pagination, HTTP caching headers
Read-only – no write endpoints; trading, deposits, and management go through the Golem’s RPC or Portal
Cache-friendly – ETag, Cache-Control, Last-Modified headers for CDN caching
Rate-limited by tier – public (no key), API key, authenticated (Privy JWT)
OpenAPI documented – full OpenAPI 3.1 spec for code generation

Response envelope

#![allow(unused)]
fn main() {
#[derive(serde::Serialize)]
pub struct ApiResponse<T: serde::Serialize> {
    pub ok: bool,
    pub data: T,
    pub meta: ResponseMeta,
}

#[derive(serde::Serialize)]
pub struct ApiError {
    pub ok: bool,  // always false
    pub error: ErrorDetail,
    pub meta: ResponseMeta,
}

#[derive(serde::Serialize)]
pub struct ErrorDetail {
    pub code: String,
    pub message: String,
    pub details: Option<serde_json::Value>,
}

#[derive(serde::Serialize)]
pub struct ResponseMeta {
    pub timestamp: u64,
    pub version: String,
}
}

Pagination

All list endpoints use cursor-based pagination:

#![allow(unused)]
fn main() {
#[derive(serde::Deserialize)]
pub struct PaginationParams {
    pub cursor: Option<String>,
    pub limit: Option<u32>,  // Default: 20, max: 100
}

#[derive(serde::Serialize)]
pub struct PaginatedResponse<T: serde::Serialize> {
    pub items: Vec<T>,
    pub cursor: Option<String>,  // None = no more pages
    pub total: u64,
}
}
