# Get outcome labels for up to 40 pump.fun mints, one payment

`GET /v1/outcome/batch`

## Request

- Base URL: `https://api.loopholetape.com`
- URL: `https://api.loopholetape.com/v1/outcome/batch`
- Auth: none required

Use when you grade a list of your own rug or graduation calls or backtest a signal on pump.fun memecoins; for one mint the $0.001 single lookup costs less. One payment returns the outcome labels of one to 40 caller-selected pump.fun mints in the order asked with the fields and the fixed public rule of the single lookup GET /v1/outcome/{mint} and is charged once whatever the answers. Each item: rugged by the public rule and when, rugged within 300 s of launch, true graduation and migration time, the creator's first sell, peak and last curve SOL, the mayhem flag, whether each label is settled (resolved) and the rule version. A mint we never saw answers known:false; a list with no known mint, more than 40, a malformed or a repeated mint is refused unpaid. No probabilities and no opinions.

## Query parameters

- `mints` string, nullable: One to 40 distinct mint addresses, comma-separated (MCP accepts an array).

## Response `200`

Paid response (header PAYMENT-RESPONSE carries the settlement)

- Envelope
  - `ok` boolean, required
  - `schema_version` '2.0', required
  - `generated_at` string, date-time, required
  - `t` number, required: unix seconds at generation
  - `coverage` 'full' | 'thin', required: the mint is inside our live window (created while our captur / thin = the mint is not in the live window (older than ~2 h of silen
  - `data` object, required
  - `meta` object, required
    - `source` string
    - `version` string
    - `feed_lag_s` number, nullable: seconds between the newest event in our tape and now (the age of the newest event we ingested; it does not say whether the capture runs behind the chain, see chain_lag_s)
    - `is_stale` boolean: the ingest age (feed_lag_s) exceeds the route's freshness limit (5 s for compact risk checks, 30 s otherwise); a paid or keyed pump.fun request is also refused above 5 s of estimated chain lag when the gate enforces (see chain_lag_s, tape_behind), which this flag does not show
    - `chain_lag_s` number, nullable: estimated seconds the newest slot in our pump.fun tape is behind the Solana RPC's processed tip (slots_behind x the measured slot time, to 0.1 s); null when the tip is unknown; absent on Robinhood Chain answers
    - `slots_behind` integer, nullable: estimated slots between the newest slot in our pump.fun tape and the Solana RPC's processed tip (a tip read every 30 s, carried forward by the wall time since at the slot rate our own reads measure); 0 when the tape is at or ahead of the estimate; null when the tip is unknown
    - `tape_behind` boolean, nullable: true when the estimated chain_lag_s is above 5 s, false within 5 s, null when there is no tip to compare; on pump.fun answers only
    - `last_slot` integer, nullable
    - `price_usd` number, nullable
    - `next` object: related resources worth calling next (paths relative to base_url)
    - `disclaimer` string

## Other responses

- `402`: Payment required (x402 v2): header PAYMENT-REQUIRED = base64 of the body
- `422`: Validation Error
