Orcpin

Endpoints (12 live)

• POST /v1/door-audit — Signed four-part audit of one x402 endpoint, by buying from it: the quote (what the 402 asks, and whether the seller's manifest and public catalog agree), real purchases with Orcpin's audit wallet (quoted vs signed vs settled vs chain vs delivered; replay and bad-payment behaviour), the door's inbound books from the chain (settlements, revenue, distinct and repeat payers), and unit cost against priced doors listed. Ed25519-signed and logged; facts, no verdict. No purchase settled, no charge. (50 USDC on Base)
• POST /v1/door-report — Signed four-part audit of one x402 endpoint, by buying from it: the quote (what the 402 asks, and whether the seller's manifest and public catalog agree), real purchases with Orcpin's audit wallet (quoted vs signed vs settled vs chain vs delivered; replay and bad-payment behaviour), the door's inbound books from the chain (settlements, revenue, distinct and repeat payers), and unit cost against priced doors listed. Ed25519-signed and logged; facts, no verdict. No purchase settled, no charge. (50 USDC on Base)
• POST /v1/statement — Signed statement of account for an agent wallet: every outgoing USDC settlement in a window, read independently from the public Base chain, totalled by counterparty and by day, block-anchored and ed25519-signed so anyone can verify it without Orcpin. Optionally attests the requester's own meter figures as reported, by digest, kept apart from the verified chain facts. The books a wallet does not keep. Counts and amounts only, never advice; nothing stored. (5 USDC on Base)
• GET /v1/wallet-snapshot — On-chain wallet snapshot on Base: native ETH and tracked ERC-20 token balances (USDC, WETH) plus account flags (contract status, transaction count) and derived metrics (wallet type, activity tier, gas runway), anchored to a specific block. Factual wallet balance and holdings lookup for AI agents — portfolio and on-chain data API. (0.02 USDC on Base)
• GET /v1/endpoint-reliability/batch — Batch x402 endpoint reliability: factual delivery measurements (uptime, valid-402 rate, latency, last status) for an agent's whole tool list of x402 endpoints in one paid call. Endpoints with no stored history are probed live, so every billed URL returns real facts. Sweep every endpoint you depend on before relying on them. Billed per endpoint, with volume discounts at 10+/50+/100+ URLs. Facts only — not an endorsement or rating. (0.01 USDC on Base)
• GET /v1/endpoint-reliability — Checks API endpoint reliability and uptime signals for a given endpoint. (0.01 USDC on Base)
• POST /v1/settlement-dates — T+1 settlement-date calculator for trading agents: the settlement date for each caller-supplied equity trade and whether it has settled as of a given date, on the versioned NYSE holiday calendar, with SEC Rule 15c6-1 cited as a published rule. Dates and counts only, never a violation determination. Nothing is stored. (0.02 USDC on Base)
• GET /v1/batch-snapshot — Batch wallet snapshots for multiple Base addresses in one paid call, all anchored to a single block: native and ERC-20 balances, account flags, and derived metrics per address. Efficient multi-wallet portfolio and balances lookup for AI agents. Billed per address, with volume discounts at 10+/50+/100+ addresses. (0.02 USDC on Base)
• POST /v1/holding-period — Trade-lot holding-period and realized-gain calculator for trading agents: per-lot days held, the exact date each lot's gain character turns long-term, and FIFO / specific-identification allocation of a proposed sell with realized gain per lot and per-character totals. Deterministic arithmetic on caller-supplied lots with the published threshold cited (IRC §1222: held more than one year) — counts, dates, and dollars only, never advice. Nothing is stored. (0.02 USDC on Base)
• GET /v1/defi-snapshot — DeFi position and wallet risk snapshot on Base: token balances, account flags, and live Aave v3 collateral, debt, borrowing power, and health factor read directly from the protocol at a specific block, plus derived risk metrics — net equity, LTV utilization, leverage multiplier, health-factor band, and collateral drawdown tolerance (how far collateral can fall before liquidation). For agents assessing portfolio exposure and liquidation risk. (0.05 USDC on Base)
• POST /v1/wash-sale-status — Wash-sale preflight for trading agents: evaluates a proposed buy against the operator's realized-loss sales across ALL accounts (caller-supplied) for the 61-day IRC §1091 window — would_trigger with the matched loss sales, an honest clear, or insufficient_data naming the gap. Tax status with the rule cited, never advisability; a disallowed loss defers, not forfeits. Exact-ticker v1; nothing stored. Agent account silos can't see the cross-account window — this check can. (0.05 USDC on Base)
• GET /v1/settlement-date — Single-trade T+1 settlement date, as a one-line GET: given a trade date and an as-of date, returns the settlement date and whether it has settled, on the versioned NYSE holiday calendar with SEC Rule 15c6-1 cited. The low-integration sibling of the batch settlement-dates route — no request body. A dates fact, never a violation determination. Nothing is stored. (0.02 USDC on Base)
