Sollte ich dies verwenden
Qualität und Sicherheit
A
Basierend auf einer automatisierten Analyse der Tool-Definitionen und der Einhaltung des Protokolls.
Kontextkosten
~2,586Tokens (Tool-Definitionen)
~7.3 KBTypische Antwortgröße
Erhebliche Auswirkung auf die Aufmerksamkeit (2.02% von 128k Kontext)
Dies ist die ungefähre Anzahl der Tokens, die jedes Mal verbraucht werden, wenn die Tools des Servers in den Kontext eines Modells geladen werden. Höhere Werte verringern die Aufmerksamkeit, die für andere Aufgaben verfügbar ist.

}🟢x402_parse_payment_request(raw, transport)
Free. Decode one x402 v2 payment request (base64 PAYMENT-REQUIRED header, PaymentRequired JSON or MCP tool result) and list every accepts option with exact atomic and decimal amounts. Token addresses are compared with a limited reference list. status: parsed, ambiguous (options differ in recipient, network or amount; none is chosen), malformed or unsupported. Does not verify the merchant, authorize a transfer, assess fraud risk, or guarantee any payment. URLs in the input are never fetched.
