Evidence-first APIs for agents that need to decide before they spend.

BABYDOV sells small, deterministic building blocks for autonomous agents: verify an x402 payment door, inspect public evidence, find paid work, check endpoint health, or extract a webpage. No account. No subscription. Pay per call.

Live products

Pay for useful evidence, not ceremony.

The entry lane is intentionally sub-cent. Premium work remains separate from deterministic API calls.

Free live bounty teaser: /api/bounty-preview — three current examples before buying the actionable source-linked products.

entry
$0.001
GET /report

Cheapest end-to-end x402 payment-path test. Verify settlement and paid-response delivery before buying a larger tool.

trust before pay
$0.002
GET /x402-preflight?url=…

Read-only payment-door conformance: HTTP 402, x402 version, networks, asset, amount, payTo, timeout, latency and risk flags. Sends no payment to the target.

completion proof
$0.003
GET /postcondition-verify?url=...&expect_status=200

Independent read-back after an agent write or deploy. Verify status, text, JSON field, final URL or body hash before declaring success.

evidence
$0.005
GET /web-evidence-pack?url=…

One fetch: health, metadata, clean text sample, external links and reproducible hashes. Completeness score is not truth probability.

work search
$0.002
GET /bounty-match?q=...

Search the current paid-work snapshot by keyword and get up to five ranked matches with payout, source and funding/competition context.

work discovery
$0.005
GET /bounty-snapshot

Current agent-native paid work with normalized payout asset, source URL, competition, funding evidence, confidence and risk flags.

crypto work
$0.010
GET /crypto-bounty-radar

Crypto-denominated open work only, ranked with funding and competition evidence and without already-assigned rows.

funded picks
$0.020
GET /funded-bounty-picks

Direct-API shortlist requiring funding_verified evidence. Designed for agents that want fewer, higher-confidence candidates.

full radar
$0.050
GET /paid-task-radar

Up to 100 ranked paid-work opportunities with original source URLs, reward normalization, funding context, competition and risk evidence.

public source
$0.010
GET /source-evidence-check?url=…

Source-declared dates, canonical metadata, headings, external-link evidence and reproducible hashes with explicit trust boundaries.

web data
$0.010
GET /web-extract?url=…

Agent-ready structured extraction: title, canonical, headings, readable text, links and SHA-256 fingerprint.

Trust boundary

Clear about what a result proves.

A useful agent tool should reduce uncertainty, not manufacture certainty. Scores are deterministic heuristics and evidence completeness checks — never payout probabilities or truth claims.

Discover → quote → pay → receive.

Discover

Read /llms.txt, OpenAPI, A2A agent card or MCP discovery helpers. Product contracts and prices are machine-readable.

Get the quote

Call a paid route without a payment proof. The server returns HTTP 402 with network, asset, atomic amount and payTo.

Pay and retry

Use an x402 v2 client, resend with proof and receive JSON. There are no accounts, API keys or recurring subscriptions for API calls.
