Sparring — Competitive challenge for sharp thinking under adversarial conditions.

SPC Day-N convective outlook GeoJSON (keyless). POST {day?}. Unpaid empty → 402; after settle empty/invalid → 400 charged:false. Disclose adjacency: nws-alerts-lookup / gdacs-events / weather-forecast / nhc-current.

Takes a transcript, SRT or WebVTT text and a mapping from labels to names, e.g. {"Speaker 1": "Anna Weber", "S2": "Interviewer"}, and replaces each label where it marks a speaker: at the start of a line before a colon, and inside WebVTT voice tags <v Speaker 1>. Words inside sentences that merely look like a label are not touched. The answer counts replacements per label and lists speaker labels found in the text that have no name in the mapping. Pure text processing on this machine.

Species Lookup: taxonomy, common names, IUCN status, range (GBIF). Species lookup by scientific or common name (GBIF): accepted name, full taxonomy, common names, IUCN Red List status, occurrence record count and top countries.

Most-recorded species within a radius of a location (birds, mammals, plants and more), with observation counts.

Parse a scientific name into genus, species epithet, subspecies or variety, authorship and year, and check capitalisation.

Resolve a species name (typos, old synonyms) to its accepted scientific name and full taxonomy, with match confidence.

TAP Certified referee fee for one job with a budget up to $25.00: the seller's code is judged on the buyer's hidden tests in a sealed sandbox, and the escrow pays out or refunds on the verdict.

Takes an audio or video file (up to 24 MB) and returns a spectrogram image: time on the horizontal axis, frequency on the vertical, intensity as colour, with scale and legend. It makes visible what the ear misses — mains hum as a line at 50 or 60 Hz, broadband noise, the cut-off of a phone or low-bitrate recording, and hard edits. Size, colour scheme and linear or logarithmic intensity are selectable. Rendered locally with ffmpeg; returned inline as PNG base64. Nothing leaves this machine.

Speech audio generator: reads any block of text aloud and returns the result as a downloadable WAV file, selectable across ten built-in voice presets. Pay-per-call with no subscription or stored text. Useful for narrating short-form content, generating spoken alerts, or producing sample audio for voice-agent testing.

Takes a recording of a talk, pitch, lesson or rehearsal of up to 30 minutes and returns delivery metrics computed from word timestamps: words per minute overall and for every minute, filler words (uh, um, äh, ähm) and hedge words (basically, actually, eigentlich, sozusagen) per minute with their most frequent forms, pauses over one second with position, average and longest sentences, and phrases of three or more words that recur.

Speech to text (Whisper large v3 turbo): send a public audio URL or base64 audio (mp3, wav, m4a, ogg, webm; up to about 10 minutes), get the transcript with detected language and timed segments.

Speech-to-text API: audio URL in, transcript out — a neural speech-recognition engine on our own hardware, ~99 languages, mp3/wav/m4a/ogg up to 25MB. For voicemail, podcast, meeting, and voice-agent pipelines. Audio deleted after processing.

Speech to text for AI agents, $0.30 per file: MP3, WAV, M4A, OGG, FLAC or WebM audio (max 5 MB, about 5 minutes) to a transcript with timed segments, detected language and optional WebVTT subtitles. One call: send a url or base64 — no upload step, no polling. No speech found means a 400 and you pay nothing. USDC on Base, no account, no API key.

Speech to text for agents: transcribe a voice note, meeting, podcast or call recording into text with timestamps, in about 100 languages with automatic language detection. Runs OpenAI Whisper (small by default, base for speed) on agentsvc.io itself, the audio is deleted after the call. Send audio_url or audio_base64 (mp3, mp4, m4a, wav, ogg, webm, flac), up to 10 minutes and 24 MB per call. Returns text, detected language, duration and segments with start and end seconds.

OpenAI's own transcription wire: POST multipart/form-data with a `file` part and get the transcript back. Point any Whisper-shaped SDK at this gateway and pay per call with USDC, no account and no API key. Same model and same four-minute cap as /api/transcribe, which takes a URL instead of an upload; /v1/pro/audio/transcriptions takes it to ten minutes.

OpenAI's transcription wire on the ten-minute tier: POST multipart/form-data with a `file` part. Same model as /v1/audio/transcriptions with a longer cap, for a recording a four-minute route refuses.

Takes an audio or video file and changes its tempo by a factor from 0.5 (half speed) to 2.0 (double speed) while keeping the pitch, using the Rubber Band time-stretching library through ffmpeg — good for faster listening, language learning at reduced speed, or fitting a voice-over into a slot. The new running time is measured and returned. All timestamps of the original scale by 1/factor. Runs locally with ffmpeg; nothing leaves this machine and nothing is stored.

Spell text using the NATO/ICAO phonetic alphabet (A→Alfa, B→Bravo, …), including digits and spaces (→Space). Characters with no phonetic spelling are clean 400s.

Detect elevated control-bypass risk from fragmented, delegated, wallet-hopped, near-threshold, burst, repeated, or concentrated autonomous spend.

SpendPreflight — trust and verification tools for stablecoin payments, built for AI agents and the people who run them. Base contract signals, not a safety verdict. Basic: bytecode/OFAC.

Honeypot/sellability, mint/blacklist powers, liquidity locks, holders and scam lists are unassessed. Missing data stays unknown; never safe-to-buy. Informational, not financial advice.
