fix(pm): make the retired canonical-market helpers fail fast - #21
Merged
Conversation
Upstream probe (api.predexon.com direct, 3 runs each, 2026-08-04): /v1/pm/markets,
/v1/pm/markets/listings and /v1/pm/outcomes/{id} all return
410 "This endpoint has been sunset as of 2026-07-20. Market matching is
discontinued."
pmMarkets / pmListings / pmOutcome have been calling them ever since. Payment
was never charged — the gateway returns before settlement — but the caller pays
a round trip to learn the endpoint is gone, and the JSDoc still advertised them
as live Tier 1 endpoints.
Kept as throwing stubs rather than deleted: removing a public method breaks
property access on upgrade, and this is a patch release. They now throw
RetiredEndpointError (new, exported, extends BlockrunError so existing catch
blocks still catch it) naming the sunset date and `pm("markets/search", { q })`
as the replacement — before any network I/O.
pmSportsCategories / pmSportsMarkets keep working but gain a note: every
sports/* path is returning a consistent upstream 500 as of 2026-08-04. That is a
partner bug, not a sunset, so the helpers stay callable for when it recovers.
eslint gains the standard argsIgnorePattern: "^_" so a deliberately unused
parameter can keep the signature intact without a disable comment.

Companion changes: BlockRunAI/blockrun#336 (gateway), BlockRunAI/blockrun-llm#40 (Python SDK),
BlockRunAI/awesome-blockrun#33 (docs).
241 tests pass, including 5 new ones pinning that the stubs throw rather than call.
