Speechmatics
Based on public pricing signals, xpay verified that Speechmatics publishes per-hour STT and per-1k-character TTS rates across Free, Pro, and Enterprise tiers, with a generous 8-hour-per-month free allowance and no card required to start. Self-serve signup at portal.speechmatics.com completes the agent-ready loop for the Pro tier.

Observational summary written by xpay from the signals captured on 2026-05-03. Not a review of the product — only of its current pricing posture for agent buyers.- Pricing is publicly visible on an indexable page — agents can read tiers without scraping past auth.
- Per-unit billing is published, so an agent can budget for a single task before committing.
- API documentation is reachable without a login — discovery and integration can happen in one session.
- Per-unit rate is concrete enough that an agent can model expected spend before issuing a request.
- A free tier exists, lowering the bar for an agent builder to prototype before committing budget.
- Some tiers are sales-led; the highest-capacity surfaces are not self-serve.
- PPU requires account creation and an issued API key; a fully unauthenticated agent purchase is not yet supported.
- No /.well-known/ai-pricing.json or equivalent machine-readable pricing manifest is published — agents must rely on HTML scraping.
How Speechmatics could lift its score
Speechmatics is already Verified. Two missing points: (1) publish /.well-known/ai-pricing.json; (2) support anonymous one-shot agent PPU via xpay widget without portal signup. Both lift to 100/100.
