Context Cost

~1,333Tokens (tool definitions)
~6.5 KBTypical response size
Moderate attention impact (1.04% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
🟢stablecoin_reserves(symbol, issuer, period, sample)

Latest parsed reserve attestation for one stablecoin issuer as JSON: as_of date, total reserves, composition by asset category, attestor, source_url, current on-chain supply (DefiLlama) and the reserve ratio. Use it when an agent needs machine-readable backing data instead of reading the issuer's PDF. Pass symbol (USDC, USDT, ...) or issuer; period=YYYY-MM selects an earlier month. Issuers without a third-party attestation return supply only with confidence 'none'. Paid: $0.02 per call; without credit you get a PAYMENT_REQUIRED result. Set sample=true for a free example response.
