# Parse a timestamp or date string into canonical forms...

`GET /api/time/parse`

## Request

- Base URL: `https://2s.io`
- URL: `https://2s.io/api/time/parse`
- Auth: API key in header `PAYMENT-SIGNATURE`

Parse a timestamp or date string into canonical forms — zero-dependency. Accepts unix seconds/millis or any standard date string (ISO-8601, RFC-2822, etc.). Returns UTC ISO, unix seconds + millis, RFC-2822, calendar components (year/month/day/hour/minute/second/weekday), ISO weekday, ISO year+week, and day-of-year. Pass an IANA timezone (tz) to also get the DST-correct local wall-clock time and UTC offset. The reliable time primitive for agents normalizing or converting timestamps.

## Query parameters

- `input` string, required
- `tz` string
- `trial` 1

## Other responses

- `200` (unresolved $ref)
- `400`: Invalid request — not charged. error.code: BAD_REQUEST or INVALID_PARAM (parameter validation; error.details.issues lists each problem), MALFORMED_JSON, or a request-specific code. Other client errors: 405 METHOD_NOT_ALLOWED (wrong verb; see the Allow header), 413 PAYLOAD_TOO_LARGE.
- `402`: Payment required. Body is the x402 PaymentRequirements envelope with a multi-network accepts array; the per-call price is in accepts[].amount (and on the operation as x-2s-price). Sign for whichever rail you hold USDC on (EIP-3009 for Base, partial SPL transfer for Solana) and retry with the PAYMENT-SIGNATURE header (X-PAYMENT also accepted for v1 clients). Also PAYMENT_SETTLE_FAILED (error envelope) when a verified payment failed to settle: error.details.chargeStatus is "not_charged" (retry with a fresh payment) or "unknown" (the authorization may still settle before its deadline — check it before retrying).
- `429`: Too many requests — RATE_LIMITED: our per-IP / per-payer limiter. Not charged; retry after Retry-After.
- `5XX`: Server-side failure. 500 INTERNAL: unexpected error; quote error.errorId (also the X-2s-Error-Id header). 502 UPSTREAM_UNAVAILABLE (or another UPSTREAM_* code): the data provider failed — composite endpoints refuse unbilled when every source fails. 503 SERVICE_PAUSED: endpoint paused by the operator kill switch, retry after Retry-After; 503 SPEND_CAP: daily upstream budget exhausted. 504 UPSTREAM_TIMEOUT. Not charged.
