The answer is a CSV of each distinct line, matched exactly as sent, marked only_a, only_b or both. It refuses empty text, more than 1,048,576 bytes or 50,000 lines, and a text without the two markers in that order. Free. The answer is the JSON envelope of https://foundry.dap.solutions/api/diff-two-line-lists, byte for byte, with the artifact hash that answered. Full rules: https://foundry.dap.solutions/hub.md
Use when you need to compare two lists of lines. Marks each distinct line only_a, only_b or both, matched exactly as sent, as a CSV. $0.01 USDC on Base per answer via x402; a refusal is free.
decode-base64-to-textchangeddescriptionmeaning changedBase64 to UTF-8 text. text holds standard base64: A to Z, a to z, 0 to 9, + and /, padding optional; white space is ignored. It refuses empty text, more than 1,048,576 bytes, the URL-safe alphabet, a length or padding that cannot be base64, and bytes that are not valid UTF-8. Free. The answer is the JSON envelope of https://foundry.dap.solutions/api/decode-base64-to-text, byte for byte, with the artifact hash that answered. Full rules: https://foundry.dap.solutions/hub.md
Use when you need to read base64 as text. Decodes standard base64 to UTF-8 text and refuses anything that is not valid base64 or not valid UTF-8, rather than guess. $0.01 USDC on Base per answer via x402; a refusal is free.
convert-unix-timestamp-to-datechangeddescriptionmeaning changedUnix timestamps to UTC dates in ISO 8601. text holds one or more timestamps, one per line: whole seconds or milliseconds, where a magnitude of 100000000000 or more is milliseconds. The answer is a CSV of input, unit and date. It refuses empty text, more than 1,048,576 bytes or 10,000 lines, and any line that is not digits with an optional leading minus inside the years 0001 to 9999. Free. The answer is the JSON envelope of https://foundry.dap.solutions/api/convert-unix-timestamp-to-date, byte for byte, with the artifact hash that answered. Full rules: https://foundry.dap.solutions/hub.md
Use when you need Unix timestamps as dates. Converts one or more timestamps, seconds or milliseconds, one per line, to UTC dates in ISO 8601 as a CSV. $0.01 USDC on Base per answer via x402; a refusal is free.
compute-day-count-to-settlementchangeddescriptionmeaning changedSettlement date on the Payments Canada holiday calendar, and the accrual fraction under ACT/360, ACT/365F, 30/360, 30E/360 or ACT/ACT-ISDA. Send all seven inputs, including acknowledge no-ruling-v1 and a freshness_tolerance in whole days written P<n>D. It refuses rather than guesses: a missing acknowledgement or tolerance, a tolerance over the ratified ceiling, calendar data older than your tolerance, a trade date outside the calendar's coverage or not a business day, and any missing, unknown or malformed input. Costs $0.01 in USDC on Base per computed answer, under x402; a refusal is not charged. The answer is the JSON envelope of https://foundry.dap.solutions/api/compute-day-count-to-settlement, byte for byte, with the artifact hash that answered. Full rules: https://foundry.dap.solutions/hub.md
Use when you need a Canadian settlement date or accrual fraction. Rolls a trade date forward on the Payments Canada calendar and counts the accrual under ACT/360, ACT/365F, 30/360, 30E/360 or ACT/ACT-ISDA. $0.01 USDC on Base per answer via x402; a refusal is free.
