What makes it different

Every tool returns a combined evidence payload with 4 layers simultaneously:

4 layers in one payload

Layer	Fields
API cleanness	`price`, `quote_currency`, `market_status`, `rwa_tokens` as objects
Verifiability	`signature`, `signer_public_key`, `content_hash`, `verify_url`
Evidence snapshot	`source_timestamp`, `valid_until`, `evidence_type`, `reference_benchmark`
ReserveOracle differentiation	`reserve_relevance`, `mica_relevance`, `mica_context`, `rank_context`

Two payload types — cleanly separated

	Asset-Level	Token-Level
Tool	`reserve_gold`, `reserve_silver`	`reserve_token_context`
Focus	Gold/Silver as reserve asset	PAXG/XAUT/BUIDL issuer + structure
`evidence_type`	`reserve_reference_snapshot`	`token_reserve_context`
Includes	Live price, LBMA benchmark, rwa_tokens	Custody, LEI, vault location, audit frequency

Tools

Tool	Credits	Description
`reserve_gold`	2u	Live XAU — full combined evidence payload
`reserve_silver`	2u	Live XAG — full combined evidence payload
`reserve_metals`	2u	Gold + Silver + ratio in one signed call
`reserve_token_lookup`	2u	Full RWA profile: PAXG, XAUT, BUIDL, USDC, RLUSD...
`reserve_gold_tokens`	3u	All gold-backed RWA tokens + live XAU spot
`reserve_mica_assets`	3u	All MiCA-relevant assets, filter by type
`reserve_asset_types`	1u	Browse 80+ protocols by asset type
`reserve_issuer`	2u	Issuer deep-profile: LEI, regulator, custody
`reserve_snapshot`	3u	Full reserve evidence snapshot
`reserve_token_context`	2u	Token-level: custody, vault location, audit frequency, regulatory status
`health_check`	free	Status

PAXG vs XAUT — instant risk differentiation

PAXG: vault_location=London, audit=monthly, regulatory_status=["NYDFS regulated", "qualified custodian"], lei="549300BHQGE3I4ZVKW46"
XAUT: vault_location=Switzerland, audit=quarterly, regulatory_status=["BVI registered", "unregulated issuer"], lei=null

Cryptographic verification

Algorithm: ES256K (secp256k1) — same as Ethereum
Public key: 0x0205705c9c2d2da037af7304164f7037e72b5fba8aae5ff6ff4e2ee848ada2f39f
JWKS: https://feedoracle.io/.well-known/jwks.json
Every payload: content_hash + real signature + verify_url with request ID

Registry Coverage

80+ protocols including gold tokens, stablecoins, tokenized treasuries, money market funds. PAXG, XAUT, BUIDL (BlackRock), OUSG (Ondo), USDC, USDT, EURC, RLUSD, EURCV, EURe, Midas (BaFin), Spiko (AMF).
