Release notes

v3.19.0 renames the public API surface from Token API to Pinax API and moves x402 enforcement to the proxy layer. Also includes a Hyperliquid /markets fix that surfaces non-spot pairs.

Rebrand to Pinax API

  • Public docs, OpenAPI metadata, banner, and the agent skill identify the API as Pinax API. (#542)
  • Repository identifier renamed from token-api to pinax-api: package name, build output, README clone commands, Docker image examples, badges, and historical changelog links. (#544)
  • Plan-limit gateway headers renamed to x-pinax-api-* (batch-size, items-returned, lowest-time-parameter). The legacy x-token-api-* headers continue to work as aliases with regression tests covering each. (#544, #545)
  • Agent skill file moved to the canonical skills/SKILL.md layout; /SKILL.md, /SKILLS.md, /skills.md, /skill.md, and /skills/SKILL.md all serve or redirect to the same content. (#540)
  • Public docs links repointed at https://app.pinax.network/docs and https://app.pinax.network/help. (#547)

Proxy-layer x402 discovery

GET /.well-known/x402 returns a machine-readable payment-discovery document describing the proxy-enforced x402 contract (authentication, verification, settlement, metering). GET /x402.json is an alias. The API layer itself no longer carries x402 middleware — discovery only. (#543)

The free-routes list is kept in sync with skills/SKILL.md and public/llms.txt, including the SKILL.md alias paths so the proxy doesn't 401 them before the in-app 301 redirect can fire. (#545)

Hyperliquid /markets returns perps

state_spot_pair_names is sourced from HL's spotMeta, which only covers spot pairs. Builder-DEX perps (xyz:CL, cash:TSLA, km:US500) and core perps (BTC, ETH) had no row to JOIN against, so market_name fell back to the raw coin and base_token / quote_token were NULL — /v1/hyperliquid/markets filters missed every perp market.

The perp fields are now derived from the coin string when the JOIN misses: strip any prefix before : to get the ticker (xyz:CL → CL), use the ticker as base_token and USDC as quote_token. HIP-4 outcome markets (#N) stay NULL — labels live in outcomeMeta, which isn't ingested yet. (#546)
