Alpha Vantage
Based on public pricing signals, xpay verified that Alpha Vantage publishes five clearly priced tiers ($49.99 / $99.99 / $149.99 / $199.99 / $249.99 per month) tied to requests/min, with a free 25-requests-per-day tier requiring no card and a Stripe-backed checkout embedded directly on /premium/. Documentation at /documentation/ is fully public. The model is well-suited to autonomous agent procurement: an agent can read price, pick a tier, and complete checkout in one HTTP session. Two missing points concern unit billing (rate-tier vs true per-call) and the absence of a structured pricing manifest.

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.
- Every advertised tier is self-serve; no tier requires scheduling a call.
- API documentation is reachable without a login — discovery and integration can happen in one session.
- A free tier exists, lowering the bar for an agent builder to prototype before committing budget.
- An anonymous purchase path is advertised — an agent can transact without account creation.
- No per-unit price was advertised, so an agent has no way to estimate the cost of a single task.
- No /.well-known/ai-pricing.json or equivalent machine-readable pricing manifest is published — agents must rely on HTML scraping.
- A unit price is published but consumption per task is not declared upfront — cost predictability is partial.
How Alpha Vantage could lift its score
Alpha Vantage is Verified. Two lifts to 90+: (1) publish /.well-known/ai-pricing.json mirroring the five monthly tiers; (2) add a true per-call PAYG SKU (e.g. $0.001/call) on top of the rate-tiered subscriptions so an agent paying via xpay/x402 can settle without a monthly commitment.
