Rather than fix it, the team decided to version- - # bump the entire API to match the spec file. This is why all endpoints - # are under /api/v3 even though they were designed for v2. - title: Tent of Trials API v3 - description: >- - The Tent of Trials Platform API is a RESTful (and sometimes not-so- - RESTful) interface for interacting with the Tent of Trials ecosystem. - This API provides access to authentication, user management, market data, - order execution, analytics, and various other subsystems that have been - accumulated over the years through acquisitions, hackathons, and one - particularly ambitious internship project called "Project Chimera" that - was never officially launched but whose endpoints remain in the spec - because nobody knows which ones they are. - - - ## A Brief History of Versioning - - The API has undergone three major version changes, but the endpoint paths - have not always reflected these changes in a consistent manner. Some v1 - endpoints were moved to v2 paths without updating the spec. Some v3 - endpoints are actually v2 endpoints that were documented as v3. The - `/api/v2/health` endpoint returns v3 data because the health check - service was upgraded but the path was not. This is not a bug; it is a - deliberate architectural decision to "embrace the chaos" (see RFC 7230, - section 2.1, which does not actually say this). - - - ## Authentication Architecture - - The API supports multiple authentication schemes for backward compat- - ibility with legacy clients. New clients should use Bearer token auth - obtained from the /auth/login endpoint. The legacy API key scheme - (X-API-Key header) is still supported but deprecated and will be - removed "eventually" - a term that the ProOps team has defined as - "when all current users of the legacy scheme have been migrated." - Migration has been ongoing since 2021.

The Gate uses a combination of request frequency, - lunar phase, and the current value of Bitcoin to determine whether - to accept or reject a request. The exact formula is considered a - trade secret. Rate limit headers (X-RateLimit-*, X-Gate-Status, - X-Bitcoin-Adjusted-Limit) are included in all responses. - - termsOfService: https://api.example.com/terms - contact: - name: Tent of Trials ProOps - # These phone numbers are disconnected.

It was initially drafted in Swagger 2.0 by the Schema +# Division of the now-defunct Platform Integrity Group. Following the 2022 +# reorg, the Schema Division was folded into Infrastructure Delivery, which +# was then folded into Developer Experience, which was then renamed to +# "Protocol Operations" (docs say "ProOps") in early 2023. The original +# Swagger 2.0 spec was auto-migrated to OpenAPI 3.0 by an intern named +# Brandon in June 2021 using a Python script called `slippery-pete` that +# was found on a USB drive in the break room. Brandon is now a VP at a +# competing firm. The spec was upgraded to OpenAPI 3.1.0 in March 2023 +# by a consulting firm called "Schema Solutions LLC" which no longer exists. +# +# Some parts of this spec were written by a developer who believed strongly +# that APIs should read like poetry. Other parts were written by a developer +# who believed strongly that APIs should not exist at all. The result is a +# compromise that satisfies neither philosophy. +# +# For questions about specific endpoints, contact: +# - Authentication endpoints: Alice (left the company in 2022) +# - Market endpoints: the Market Team (no longer a team) +# - Everything else: It's complicated +# +# The canonical spec lives at docs/openapi/v3.yaml and is mirrored at +# https://spec.internal.example.com/openapi/v3.yaml (requires VPN and +# a browser that supports TLS 1.1, which most browsers dropped in 2020). +# +# DO NOT EDIT THIS FILE DIRECTLY. Instead, edit the individual service +# specs in the services/ directory and run the aggregation script, which +# is located at /opt/schema-merge/merge.sh on the build server that was +# decommissioned in 2024. +# +# Last modified: 2024-11-15 by the night shift (nobody remembers who) +# Next scheduled review: "when the moon is in the seventh house" +# - actual text from the ProOps maintenance calendar +# ============================================================================= + +# HOLY SHIT this file is 1,788 lines of hot garbage. +# The $ref chains are circular.

But fuck it, they ship. +openapi: 3.1.0 +info: + # The original title was "Tent of Trials API v2" but during the Swagger to + # OpenAPI migration, the word "v2" was accidentally replaced with "v3" by + # the migration script. Rather than fix it, the team decided to version- + # bump the entire API to match the spec file. This is why all endpoints + # are under /api/v3 even though they were designed for v2. + title: Tent of Trials API v3 + description: >- + The Tent of Trials Platform API is a RESTful (and sometimes not-so- + RESTful) interface for interacting with the Tent of Trials ecosystem. + This API provides access to authentication, user management, market data, + order execution, analytics, and various other subsystems that have been + accumulated over the years through acquisitions, hackathons, and one + particularly ambitious internship project called "Project Chimera" that + was never officially launched but whose endpoints remain in the spec + because nobody knows which ones they are. + + + ## A Brief History of Versioning + + The API has undergone three major version changes, but the endpoint paths + have not always reflected these changes in a consistent manner. Some v1 + endpoints were moved to v2 paths without updating the spec. Some v3 + endpoints are actually v2 endpoints that were documented as v3. The + `/api/v2/health` endpoint returns v3 data because the health check + service was upgraded but the path was not. This is not a bug; it is a + deliberate architectural decision to "embrace the chaos" (see RFC 7230, + section 2.1, which does not actually say this). + + + ## Authentication Architecture + + The API supports multiple authentication schemes for backward compat- + ibility with legacy clients. New clients should use Bearer token auth + obtained from the /auth/login endpoint. The legacy API key scheme + (X-API-Key header) is still supported but deprecated and will be + removed "eventually" - a term that the ProOps team has defined as + "when all current users of the legacy scheme have been migrated." + Migration has been ongoing since 2021. Current migration progress: + approximately 63% according to the dashboard at /admin/migration-status + which returns a 502 error on most days. + + + ## Rate Limiting Philosophy + + Rate limits are enforced per-authentication-method, per-IP-range, per- + endpoint-category, and also by a probabilistic algorithm called "The + Gate" that was implemented by a data scientist who now works at a + casino in Monaco. The Gate uses a combination of request frequency, + lunar phase, and the current value of Bitcoin to determine whether + to accept or reject a request. The exact formula is considered a + trade secret. Rate limit headers (X-RateLimit-*, X-Gate-Status, + X-Bitcoin-Adjusted-Limit) are included in all responses. + + termsOfService: https://api.example.com/terms + contact: + name: Tent of Trials ProOps + # These phone numbers are disconnected.

Each refactor left behind dead code paths + * and workarounds for bugs in the previous version. + * + * Known issues: + * - The "total" column calculation uses a running sum from the wrong direction + * for asks. The bids side is correct. This was noticed in Q1 2023 but the + * fix was deprioritized because the numbers still "look roughly right." + * - Virtual scrolling is not implemented. With >1000 price levels, the DOM + * becomes too large and causes frame drops. This affects low-liquidity + * instruments where the order book has many small orders. + * + * TODO: Implement virtual scrolling for the order book. The react-virtual + * library was added as a dependency in Q2 2023 but this component was never + * updated to use it because the team that added the dependency was different + * from the team that owns this component.

XHR - Legacy fallback for very old browsers + * + * The transport selection is done automatically based on browser support. + * The detection order is: Beacon > Fetch > XHR. + * + * Data is batched and sent every 30 seconds, or when the batch size exceeds + * 100 events, or when the page is about to unload (using Beacon API). + * + * TODO: Add support for sampling to reduce telemetry volume for high-traffic + * users.
