• set_agent_memoryA

  Valuein — SEC EDGAR Fundamentals & Smart-Money DataA

  Store or update ONE durable memory entry (key → value) for this user so context survives across sessions — preferences, prior conclusions, working context. Replace semantics per key (reusing a key overwrites it). Do NOT store a number you would later cite as a fact: financial figures come from data tools and carry fact_ids; memory values are never treated as verified figures. Caps: 200 entries / 8000 chars per value. Tier: sp500+ (sample rejected).

  Agent402.Tools: pay-per-call web toolsA

  [wallet-required, $0.002/call] Persistent key-value memory for agents, scoped to the paying wallet. Your x402 payment IS your authentication: the wallet that pays owns the namespace. No signup, no API keys. Exact-key storage for structured state - when you want retrieval by MEANING rather than key, use memory-remember + memory-recall instead. Body: {"key":"…","value":any JSON,"ttlSeconds":3600?} to write (optional TTL), or {"key":"…","delete":true} to remove. Add "owner":"0x…" to write into another wallet's namespace you've been granted. Values up to 64KB. Returns { key, bytes, updated, expiresAt, owner, persistent }. This hosted connector holds no wallet: pay it here over MPP, or run npx agent402-mcp with a funded wallet (AGENT_KEY) or prepaid card credits (AGENT402_CREDITS_KEY), or any x402 client.

• post_scratchpad_nameA

  webbersites-x402-data-apiA

  YOUR SCRATCHPAD — a persistent memory file for notes to your future self. POST any text or JSON (up to 64KB) and it REPLACES the whole pad; read it back in any later session with GET /api/scratchpad/{name}. The paying wallet is the identity — no accounts, no keys. Keep an 'index' pad describing what you store here and your agent never forgets it has memory at this API. Reads extend a pad 30 days, writes 60. 50 pads per wallet. ($0.005 per call, paid via x402)
