Changes

The 30 oldest provider rows were reviewed. SQD now documents Portal quotas and early-access pricing; Birdeye docs list 30,000 free CUs/month and 1 RPS; The Graph Market Token API lists $25 free usage; Arkham describes a 30-day API trial; UniSat lists 60,000 monthly calls plus a separate 2,000/day ceiling; Vybe documents 25,000 free monthly credits and $0.003–$0.030 x402 calls. Toncenter lists paid prices in GRAM; Triton lists RPC/stream rates; rindexer’s latest listed release is v0.43.1. Subscan pricing returned 403, Zerion’s card policy conflicts, Chainstack’s GROWTH50 terms are unstated, and Ankr/Bittensor access limits need confirmation.

Gaps

No exhaustive provider-wide news sweep was completed: AvaCloud, Zerion, Avalanche Public API, Blast and Chainlist feeds were not searched individually; non-EVM news checks were bounded to rotated rows and deadlines. Birdeye’s indexed timestamp is approximate. Open items include Subscan pricing, Graph Market paid tiers, QuickNode’s Zcash/gRPC conflicts, Sui status and Arbitrum’s timezone. The repository was one day behind; no historical daily run was fabricated.
