Summary

This PR adds Snap-facing pricing support for Chain 138 and documents the exact integration contract for current and historical valuation.

What Changed

  • add Snap methods for:
    • current price
    • historical price
    • pricing context
  • update Snap manifest and README
  • add integrator guidance for pricing payloads and fallback behavior
  • add a dedicated requirements doc for Snap-grade pricing integration

Validation

  • verified request/response expectations against the live token-aggregation API
  • aligned docs with the deployed pricing-context flow

Notes
