Blocksize market intelligence package

Signed Oracle Feeds for agents and builders.

Methodology, provenance, and qualification requirements for signed market data used by AI agents, oracle publishers, and onchain applications.

Open Market Intelligence API Read Package JSON Live Feed Status

Designed to be found by humans, models, and agents.

Use this page to evaluate whether a price object is traceable, replayable, rights-cleared, and cryptographically signed for its intended consumer.

AMM State Price API

Cached AMM state prices for covered protocol symbols, read from Blocksize state_subscribe when available and resolved through state_instruments plus state_pool as a documented fallback.

Asset coverage

Route discovery and paid access stay separated so agents can inspect before purchase.

cryptooraclesstate-data

Definition and coverage boundary

A signed oracle feed binds a market-data payload to a timestamp, methodology version, lineage record, signer identity, key identifier, and verifiable signature. Hash-linked receipts are provenance evidence, but are not described as signed unless a signature envelope is present.

supported
Hash

receipt and provenance lookup

Audit receipts expose stable request/response hashes, timestamps, sources, and lookup URLs.

candidate
Method

oracle/state qualification

State and candidate RWA lanes expose methodology and promotion-gate evidence.

not claimed
Signature

cryptographic signature envelope

Do not infer a signature unless algorithm, key ID, payload digest, and signature are returned.

Coverage snapshot as of 2026-07-22. Candidate and catalog counts are not production claims.

Methodology

How evidence reaches production.

  1. Canonicalize the payload and bind it to an observation timestamp and methodology version.
  2. Record source endpoints, upstream timestamps, asset identity, market state, and transformation lineage.
  3. Apply freshness, deviation, depth, manipulation, independence, and market-closure checks.
  4. Generate stable request and response digests and a public provenance lookup URL.
  5. When signature delivery is enabled, sign the canonical envelope and publish algorithm, key ID, and verification instructions.

Rights boundary

Access and redistribution are separate.

  • A cryptographic signature proves signer control; it does not grant redistribution rights.
  • Source lineage and rights scope must remain attached to downstream oracle publication.
  • Key rotation, revocation, retention, and verification policy must be versioned and public before production promotion.
Named use cases

Built for decisions that need lineage.

  • Liquidation-safe perpetual and lending reference prices
  • AI-agent evidence objects and auditable market briefs
  • Cross-provider oracle independence monitoring
  • Onchain verification of timestamped market observations
